Synthesis of crystalline two-dimensional conjugated polymers through irreversible chemistry under mild conditions.

ABSTRACT: Two-dimensional conjugated polymers (2DCPs) are a class of monolayer to multilayer crystalline polymeric materials with conjugated linkages at two-orthogonal directions that promise applications from membranes to electronics. Current interfacial synthesis methods have succeeded in constructing 2DCPs from dynamic covalent chemistry, e.g., imine linkages. However, these methods are unsuitable for fabricating the 2DCPs of robust olefin linkages due to the inadequate reversibility. Here we report the synthesis of 2DCPs linked by olefin bonds via amphiphilic-pyridinium-assisted aldol-type interfacial polycondensation. The synthesis is achieved by an alkyl-quaternized trimethylpyridine that can self-assemble into ordered monolayer at water interface and further react in situ with multifunctional
