设计并合成了四个含有N,N-二甲基芳基胺单元作为供电子基团的三芳基胺衍生物(XS6 – 9)。通过标准操作将这些染料应用于纳米晶TiO 2染料敏化太阳能电池。对于典型的设备,最大的单色入射光子-电流转换效率(IPCE)可以达到93%,而短路光电流密度(J sc)为10.8 mA cm -2,开路光电压(V oc)690 mV和填充因子(FF)0.61,对应于4.54%的总转换效率。
Synthesis of triphenylamine (TPA) dimers and applications in cell imaging
摘要:
A variety of triphenylamine (TPA) are shown to undergo C-C bond formation using quinone-based chloranil/H+ reagent as the metal free oxidative system to afford triphenylamine dimers very conveniently. Then, TPA dimers have been further converted to the emission color tunable compounds via simple chemical transformations. Importantly, we established the primary relationship between chemical structures with the optical behaviors from the aspect of emission (lambda(em)) wavelength, fluorescence life time (tau) and aggregation-induced-emission (AIE) property in this work. The further application of these compounds to cell imaging was fully demonstrated.
