| 1 | Synthesis of an AIE-active fluorogen and its application in cell imaging显示文摘A fluorogen named 1-decyl-1-methyl-2,5-bis{4-[(N,N-diethylamino)methyl]phenyl}-3,4-diphenylsilole (3) was synthesized. It emitted weakly as isolated molecule but strongly as supramolecular aggregate, showing a characteristic behavior of aggregation-induced emission (AIE). The molecules of 3 formed highly emissive nanoparticles in aqueous media, which quickly and selectively marked cytoplasm of HeLa cells and posed no toxicity to the living cells. The fluorogen is thus a promising candidate mate-rial for cell imaging as a sensitive, selective and cytocompatible biosensor. | LAM Jacky Wing Yip FAISAL Mahtab NG Ka Ming LUO Kathy Qian | 2009 | Science China Chemistry2009，52，1： | 12 |
| 2 | 硝基苯衍生物结构与其淬灭聚(2,5-二戊氧基对亚苯基亚乙炔基)荧光效率的关系显示文摘The poly(2,5-dipentyloxy-para-phenylene ethynylene)(P) was synthesized by Pd-catalyzed Sonogashira coupling reaction.Due to causing energy transfer between the nitrobenzene’s quenchers and the polymer chains through the charge-transfer interaction,the fluorescence quenched properties of P varied obviously with the para-substituting group’s structure in the nitrobenzene derivatives.The fluorescence quenching efficiency of quenchers improved with increasing of electron repulsion capability of the para-substituting group.The fluorescence quenching efficiency increased nonlinearly with the concentration of the quenchers and had,however,no relation with the quenching time. | 徐宏丽 佟斌 石建兵 刘旸 田旭玲 董宇平 LAM Jacky Wing Yip 唐本忠 | 2007 | 高分子学报2007，17，3： | 8 |
| 3 | HYPERBRANCHED CONJUGATIVE MACROMOLECULES CONSTRUCTED FROM TRIPLE-BOND BUILDING BLOCKS显示文摘Polycyclotrimerization and polycoupling of acetylenic monomers respectively furnish hyperbranched polyarylenes and polyynes with high molecular weights (up to 1 × 106) in high yields (up to 99.9%). The polymers possess low intrinsic viscosities and high thermal stabilities, losing little of their weights when heated to > 400℃. Upon pyrolysis at > 800℃, the polymers graphitize with high char yields (up to 86%). Hyperbranched polyarylenes efficiently emit deep-blue to blue-green lights with fluorescence quantum yields up to 98% and strongly attenuate intense laser pulses with optical power-limiting performances superior to that of C60, a well-known optical limiter. Poly(alkenephenylenes), poly(aroylarylenes) and polyynes are readily cross-linkable by UV irradiation, serving as excellent photoresist materials for the generation of patterns with nanometer resolution. Thin films of hyperbranched polyynes exhibit very high refractive indexes (n up to 1.86). The internal and terminal acetylene moieties of the polyynes readily form complexes with cobalt carbonyls, which can be transformed into soft ferromagnetic ceramics with high magnetic susceptibilities (Ms up to ca. 118 emu/g) and near-zero magnetic losses. | Matthias HaeuBler Hong-chen Dong Jacky Wing Yip Lam Rong-hua Zheng An-jun Qin Ben-zhong Tang | 2005 | Chinese Journal of Polymer Science2005，23，6： | 7 |
| 4 | LINEAR AND HYPERBRANCHED POLYMERS WITH HIGH THERMAL STABILITY AND LUMINESCENCE EFFICIENCY显示文摘New acetylene monomers, 6-{[(1-naphthylethynyl-4-phenyl)carbonyl]oxy}-l-phenyl-l-hexyne (1), 2,5-diethynylthiophene (3), and 4,4′-diethynylbiphenyl (6) were synthesized. Homopolymerization of 1 and copolycyclotrimerizations of 3and 6 with 1-heptyne and l-octyne have been achieved with WCI6- and TaC15-Ph4Sn catalysts, respectively, giving soluble linear disubstituted polyacetylene (2) and hyperbranched polyarylenes (5 and 8) with high molecular weights (up to 1.2 ×105) in high yields (upto 98%). The structures and properties of the polymers are characterized and evaluated by IR, NMR,TGA, UV, photoluminescence (PL), and electroluminescence (EL) analyses. All the polymers possess high thermal stability and emit strong blue light upon photoexcitation. The intensity of the emitted light is greater than that of poly(1-phenyl-1-octyne), a well-known highly luminescent disubstituted polyacetylene. Little aggregation-induced red shift in the PL was observed in the thin films of the polymers. By constructing a multi-layer EL device, high EL quantum yield (0.18%) has been achieved in 2, which are the best results for substituted polyacetylenes attainable so far. | Jacky Wing Yip Lam Jing-dong Luo Han Peng Zhi-liang Xie Kai-tian Xue Yu-ping Dong Lin Cheng Cheng-feng Qiu Hoi Sing Kwok Ben-zhong Tang Departments of Chemistry and Electrical & Electronic Engineering Hong Kong University of Science & Technology Clear Water Bay, Kowloon, Hong Kong China | 2001 | Chinese Journal of Polymer Science2001，19，6： | 2 |
| 5 | Theoretical study of substituent effect on the charge mobility of 2,5-bis(trialkylsilylethynyl)-1,1,3,4-tetraphenylsiloles显示文摘The theoretical calculation of the charge mobility of 2,5-bis(trialkylsilylethynyl)-1,1,3,4-tetraphenylsiloles is presented.B3LYP/6-31* calculations demonstrated that these silole molecules possessed large coupling matrix elements and reorganization energies for electron and hole transfers and high electron mobilities.The bulkiness of the trialkyl substituents influenced the charge mobility of the silole molecules,with the smaller trimethyl group imparting higher charge mobility than triethyl and triisopropyl substituents. | LAM Jacky Wing Yip | 2010 | Science China Chemistry2010，53，11： | 1 |

| 7 | A facile design for multifunctional AIEgen based on tetraaniline derivatives显示文摘Aniline oligomers have been widely used in many fields due to their excellent physicochemical properties. Owing to strong intermolecular interactions, their emission is always weakened or quenched when they are in high concentration or aggregated state, which greatly limits their fluorescent applications. Inspired by the concept of aggregation-induced emission(AIE), herein we introduced large steric groups onto the aniline oligomer to prevent the formation of packing structure. In particular, diphenyl vinyl group was bonded with oligomeric tetraaniline by a facile synthetic procedure with high yield. The obtained aniline oligomer derivative exhibited typical AIE features, which was also confirmed by density functional theoretical calculation. More importantly, this AIE oligomer was able to detect Fe^(3+) ions selectively and quantitatively. The fluorescence intensity decreased linearly along with the increment of Fe^(3+) concentration. Moreover, we demonstrated that this AIE oligomer could stain live bacteria, such as E. coli and S. aureus efficiently. All these results suggest that such a readily accessible and multifunctional tetraaniline derivative provides a new platform for the construction of fluorescent materials. | Beibei Liu Wei He Hao Lu Kun Wang Mingming Huang Ryan Tsz Kin Kwok Jacky Wing Yip Lam Longcheng Gao Jiping Yang Benzhong Tang | 2019 | Science China Chemistry2019，62，6： | 1 |

| 11 | 重氮树脂-聚(4-羧酸苯基)乙炔自组装膜与光电转换显示文摘A novel multiplayer film was assembled from poly[(4 carboxyphenyl)acetylene](PCPA) and diazoresin(DR) in aqueous solution via electrostatic attraction. Under UV irradiation, following the decomposition of diazonium group between the adjacent interfaces of the multiplayers, the ionic bonds of the self assembly film convert to covalent bonds and the film becomes very stable toward electrolyte solutions. Thus the photoelectric conversion property of poly[(4 carboxyphenyl)acetylene] containing film can be measured in conventional three electrode photoelectrochemical cell, and 0.5 mol/L KCl solution can be used as the supporting electrolyte. The photocurrent spectroscopy responses coincide with the absorption spectrum of the irradiated self assembly film, which indicates that the irradiated DR/PCPA film is responsible for the photocurrent generation. | 姚桂君 董宇平 曹廷炳 杨书明 Jacky Wing Yip Lam 唐本忠 | 2002 | 高等学校化学学报2002，23，6： | 0 |
| 12 | Aptamer-Anchored Rubrene-Loaded Organic Nanoprobes for Cancer Cell Targeting and Imaging显示文摘Fluorescence imaging has become an indispensable technique in cancer research because it can reveal informative molecular,cellular,anatomical,and func-tional insights.Development of advanced fluores-cent probes with superior sensitivity and biological selectivity for fluorescence imaging is thus impera-tive.To move forward in this direction,we developed an easy self-assembly method for fabricating apta-mer-anchored rubrene-loaded organic fluorescent nanoprobes.The aptamer-modified organic nanop-robes integrated the best features of the organic light-emitting materials and the aptamers,thus endowing them with excellent cell-targeting capabil-ity,high stability,and good biocompatibility.By using this general method,a variety of biocompatible and highly bright organic fluorescent nanoprobes based on novel organic light-emitting materials with specific recognition could be easily constructed for real-time biosensing and long-term biomedical imaging. | Yuanyuan Li Chuansheng Li Tao Jiang Lihua Zhou Pengfei Zhang Ryan T.K.Kwok Jacky Wing Yip Lam Ping Gong Lintao Cai Ben Zhong Tang | 2019 | CCS Chemistry2019，1，3： | 0 |
