Decoding the Morphological Diversity in Two Dimensional Crystalline Porous Polymers by Core Planarity Modulation

Abstract

Abstract Two new chemically stable triazine‐ and phenyl‐core‐based crystalline porous polymers (CPPs) have been synthesized using a single‐step template‐free solvothermal route. Unique morphological diversities were observed for these CPPs [2,3‐DhaTta (ribbon) and 2,3‐DhaTab (hollow sphere)] by simply altering the linker planarity. A detailed time‐dependent study established a significant correlation between the molecular level structures of building blocks with the morphology of CPPs. Moreover, a DFT study was done for calculating the interlayer stacking energy, which revealed that the extent of stacking efficiency is responsible for governing the morphological diversity in these CPPs.
