| 1 | Highly sensitive and selective ratiometric fluorescent copper sensors: Different binding affinities modulated by three separate side chains of naphthalimide显示文摘A series of compounds 1-11 with different side chains of naphthalimide as fluorescent copper sensors were designed and synthesized. Compounds 1, 9, 10 and 11 presented a high selectivity to Cu2+ in a neutral aqueous environment. Here 1, 9 and 10 showed selectivity and affinity to Cu2+ with an association constant of about ~106. It gave somewhat response to Ag+, Co2+, Ni2+ and Fe2+ while 1 detected copper. 9 and 10 displayed better selectivity by changing their hydrophobic side chains to the hydrophilic ones on imide moieties. 11, with one flexible side chain, showed high selectivity and an association constant (Ka = 2.2 × 108), which were much higher than those of 1, 9 and 10. These results indicated that the selectivity and affinity could be improved by changing side chains of naphthalimide. That might provide a novel strategy or method for the development of fluorescent sensors. | XU YuFang LU Feng XU ZhaoChao CHENG TanYu QIAN XuHong | 2009 | Science China Chemistry2009，52，6： | 4 |
| 2 | Reversible fluorescent probes for chemical and biological redox process显示文摘Oxidation and reduction are important chemical and biological processes. The redox state is related with physical functions and health. Thus, it is meaningful to develop tools for study the redox process.Fluorescence is a powerful method to connecting the microcosm and macrocosm. In this review, we discuss the recent progress of reversible fluorescent probes for chemical and biological redox process according to different active centers. | Biao Li Zhaoshuai He Hanxin Zhou Han Zhang Tanyu Cheng | 2017 | Chinese Chemical Letters2017，28，10： | 1 |

| 5 | Acid-induced tunable white light emission based on triphenylamine derivatives显示文摘A series of triphe nylamine(TPA)derivatives with various substituent groups were prepared and showed different absorption and fluorescence characteristics due to the substituent effect.On account of the existence of pyridine units,these TPA derivatives exhibited acid-induced tunable multicolor fluorescence emission including white light emission.In addition,acid-induced fluorescence regulation of these compounds has been also realized in the solid state,which enable them to be successfully constructed the stimuli-responsive fluorescent films and fluorescent inks for inkjet printing. | Xi Liu Yi Qin Junlong Zhu Xiaoli Zhao Tanyu Cheng Yanrong Jiang Haitao Sun Lin Xu | 2021 | Chinese Chemical Letters2021，32，4： | 1 |

| 7 | Fluorescence-resonance energy transfer(FRET)within the fluorescent metallacycles显示文摘During past few years,the construction of fluorescent metallacycles featuring the fluorescenceresonance energy transfer behavior has attracted extensive attention due to their diverse applications such as real-time monitoring the dynamics of coordination-driven self-assembly,photoswitching fluorescence-resonance energy transfer,and light-controlled generation of singlet oxygen for cancer therapy.This review focuses on the recent advances on the design principles,preparation methods,optical properties,and the wide applications of fluorescent metallacycles with the FRET property. | Qinghui Ling Tanyu Cheng Shaoying Tan Junhai Huang Lin Xu | 2020 | Chinese Chemical Letters2020，31，11： | 0 |
| 8 | One-pot enantioselective construction of 3,4-dihydro-2H-1,4-oxazines over Ru/Au relay catalysis and its mechanistic serendipity显示文摘The preparation of enantiomerically pure 1,4-oxazines remains a continuous challenge in synthetic chemistry because of their potential application in the total synthesis of morpholines.Herein,a one-pot asymmetric transfer hydrogenation/cyclization enantio-relay process catalyzed by Ru and Au bimetallic catalysts was developed.This enantio-relay process firstly allows the asymmetric transfer hydrogenation of alkynones to form chiral alkynols in the presence of(S,S)-mesityleneRuClTsDPEN(TsDPEN=N-(p-toluenesulfonyl)-1,2-diphenylethylenediamine)and then the chiral alkynols could be converted into 3,4-dihydro-2H-1,4-oxazines in moderate to good yields with excellent enantioselectivity retention accompanied by AuCl(PPh_(3))/AgNTf_(2) and HCOOH.A series of sulfonamide-tethered alkynones were well tolerated in this process.Mechanistic studies indicated that the alkynols formed in the first step were initially transformed into a methylenemorpholine intermediate when AuCl(PPh_(3))/AgNTf_(2) and HCOOH were added,which can be further isomerized into chiral 3,4-dihydro-2H-1,4-oxazines with the addition of a second HCOOH.This protocol offers not only a practical method to access 3,4-dihydro-2H-1,4-oxazines from alkynones in an enantioselective version,but also enriches the arsenal of gold chemistry from a mechanistic point of view. | Dongfeng Yang Chengyi Wang Yu Wang Guohua Liu Tanyu Cheng Rui Liu | 2022 | Organic Chemistry Frontiers2022，9，1： | 0 |
