合成了一类新的二氨基取代π扩展吩嗪化合物，并对其光物理性质进行了研究。U型二氨基吩嗪在溶液中表现出光致发光，量子产率适中。二氨基芳香族化合物适用于与甲醛的缩聚反应，形成Tröger碱梯聚合物。所得到的微孔梯形聚合物对氮气具有较高的CO2吸附选择性，这很可能是由于吩嗪环上存在碱性氮原子所致。
A new class of diamino‐substituted π‐extended phenazine compound was synthesized, and its photophysical properties were investigated. The U‐shaped diaminophenazine displayed photoluminescence in solution with moderate quantum yield. The diamino aromatic compound was found applicable to the poly‐condensation with formaldehyde to form Tröger's base ladder polymer. The obtained microporous ladder polymer features high CO2adsorption selectivity against N2, most likely due to the presence of basic nitrogen atoms in the phenazine rings.
