1,2,5-噻二唑-[3,4-g]喹喔啉衍生物近红外荧光发射特性研究
Study on near-infrared fluorescence emission characteristics of 1,2,5 -thiadiazole-[3,4-g]quinoxaline derivatives
摘要
Abstract
The application of near-infrared fluorescence of organic molecules in nonlinear optical devices and biological imaging are very important.The near-infrared fluorescence emission nonlinear optical properties of the two organic dyes 1,2,5-thiadiazole-[3,4-g]quinoxaline derivatives(TQ1 and TQ2)were studied.At the excitation wavelength of 532nm,the chromophoric group(TQ2)with thiadiazolyl as the donor was observed to exhibit a pronounced saturated absorption behavior,but no observation was observed in the derivative of bi-phenyl(TQ1)as a donor.Saturated absorption behavior;the chromophore(TQ2)with thiadiazolyl as a donor exhibits a larger two-photon absorption cross section in the second biological window and has stronger near-in-frared fluorescence properties.Such thiazole-quinoxaline derivatives will have very broad application prospects in solid state optoelectronic devices and bioimaging.关键词
