合成了一系列含6或7个侧位稠合六元环的二氢和四氢四氮杂并苯二酰亚胺。表现出卤致变色和氧化还原可切换的可见-近红外光学特性。获得了二氢四氮杂并苯衍生物的五元互变异构体，并对其进行了表征，其表现出足够的稳定性，并与更常见的苯型互变异构体平衡存在。
A series of dihydro- and tetrahydro-tetraazaacene diimides containing 6 or 7 laterally fused six-membered rings were synthesized. Halochromic and redox-switchable vis-NIR optical characteristics were exhibited. Quinonoid tautomers of dihydrotetraazaacene derivatives were obtained and characterized, which exhibited adequate stability and existed in equilibrium with the more commonly observed benzenoid tautomer.
