在刚性n -聚吲哚链之间构建了金属配位交联，交联膜具有高抗拉强度、高耐热性和优异的极性耐溶剂性。非共价交联可以通过外焦磷酸盐进一步去除，使交联聚合物具有可回收性。利用金属配位对相邻联吡啶结构的荧光猝灭效应，可以对聚合物的抗拉强度和玻璃化转变温度进行无损检测。
Metal coordination crosslinking between stiff N-polyindole chains was constructed, and the crosslinked films exhibited high tensile strength, high heat resistance and excellent polar solvent resistance. The noncovalent crosslinking can be further removed via external pyrophosphate, which endows the crosslinked polymer with a recyclable behavior. The tensile strength and glass transition temperature of the polymers can be nondestructively detected by taking advantage of the fluorescence quenching effect of metal coordination to the adjacent bipyridine structure.
