Synthesis and Cellular Imaging Studies of Three Compounds with D-A-π-A Configuration
In this study,three compounds A1,A2 and A3 with D-A-π-A configuration were synthesized using triphenylamine,carbazole and coumarin as building blocks,respectively.The structures of the three compounds were characterized by mass spectrometry,infrared spectroscopy,hydrogen nuclear magnetic resonance spectroscopy and carbon spectroscopy.Combined with theoretical calculations,the optical properties of compounds A1,A2 and A3 were investigated using UV-visible absorptionand fluorescence emission spectroscopy systems.The results showed that the three compounds have favorable optical characteristics.MTT assay and laser confocal imaging indicated that the three compounds had low cytotoxicity and could be used for cellular imaging.
