Wafer-sized multifunctional polyimine-based two-dimensional conjugated polymers with high mechanical stiffness
One of the key challenges in two-dimensional (2D) materials is to go beyond graphene, a prototype 2D polymer (2DP), and to synthesize its organic analogues with structural control at the atomic- or molecular-level. Here we show the successful preparation of porphyrin-containing monolayer and multilayer 2DPs through Schiff-base polycondensation reaction at an air-water and liquid-liquid interface, respectively. Both the monolayer and multilayer 2DPs have crystalline structures as indicated bydoi:10.34657/9014 fatcat:is3ds5ymojg2vbzipwgkta6syi
