摘要通过一步反应合成了一系列结构简单的2,5-二氨基对苯二甲酸酯,通过溶剂蒸发法得到了大尺寸且表面光滑的棒状单晶。这些晶体显示出明亮的发射,荧光量子产率高于0.2。它们显示出波导特性,并且已针对一种化合物的晶体确定了波导的低光损耗系数。另外,该晶体可以引起从其发出的光的线性偏振,其偏振对比度为0.70。最重要的是,这些晶体可以实现放大的自发发射(ASE),包括红色ASE,其能量阈值为72–198 kW / cm 2,并且增益系数高,

Single benzene-based fluorophore (SBBF) is a representative small-size fluorescent dye which has an electron push-pull structure within a benzene backbone. In this work, we disclosed a new amino-SBBF (ASBBF) library that has various alkyl-amines and aromatic-amines on the electron-donating site. The synthesis, photophysical properties, quantum chemical calculation, two-photon responsiveness, and bioimaging
A new molecular design of organic emitters exhibiting efficient solid-state fluorescence, which involves planarity breaking of N,N-diorganoquinacridones, is presented. The new design principle led to the development of dimethyl 2,5-diaminoterephthalates and 2,5-diamino-1,4-diaroylbenzenes, which emitted green to yellow and yellow to red light with high-to-excellent quantum yields, respectively. In addition, the photoluminescence properties of the diaroylbenzenes were dependent on the morphology and reversibly variable by thermal and solvent vapor stimuli. (C) 2011 Elsevier Ltd.
