In the present paper a novel way of symmetric conjugation extension along molecular axes of perylene dianhydride chromophore has been devised to achieve lengthy delocalized electronic species exhibiting red shifted absorption and emission of UV-Visible radiations. During synthetic pathway free amino Schiff bases of novel aldehydes with 4-amino acetanilide have been condensed with perylene dianhydride
在本文中,已经设计了一种新颖的沿per二酐发色团沿分子轴对称共轭扩展的方法,以实现长的离域电子物种,表现出红移吸收和发射紫外可见辐射。在合成途径中,将新型醛与4-氨基乙酰苯胺的游离氨基席夫碱在高温条件下与ylene二酐在喹啉中缩合。合成了双per二酰亚胺席夫碱(5a-e),其在461-526 nm处吸收λmax,在525-550 nm处显示发射。新获得的化合物的结构已通过1 H和13确认C-NMR研究。这些染料的循环伏安分析显示出氧化峰和还原峰,这间接证明了它们作为用于太阳能电池中半导体敏化的n型材料的潜在用途。发现LUMO和HOMO能级分别在-4.21至-5.20和-6.75至-7.57 eV的范围内。 具有Schiff碱的多色双轴双联per生色团,合成表征和电化学研究。Ghulam Shabir,Aamer Saeed,Muhammad Arshad和Muhammad Zahid。
