Azulenocyanine, having four azulene units fused to a tetraazaporphyrin skeleton, is a structural isomer of naphthalocyanine. We synthesized the first example of an azulenocyanine from 1,3-di-tert-butyl-5,6-dicyanoazulene. The macrocycle exhibits broad absorption over the visible and near-IR regions far beyond 1000 nm. Theoretical calculations and electrochemical experiments show the LUMO energy level
具有四个与四氮杂卟啉骨架融合的 azulene 单元的 Azulenocyanine 是萘酞菁的结构异构体。我们从 1,3-二叔丁基-5,6-二氰基蕈烯合成了菘蓝花青的第一个例子。大环在远超过 1000 nm 的可见光和近红外区域表现出广泛的吸收。理论计算和电化学实验表明 LUMO 能级显着降低。Azulenocyanine 代表了一种新型的氧化稳定近红外染料。
