The connectivity of building units for 3D covalent organic frameworks (COFs) has long been primarily 4 and 6, which have severely curtailed the structural diversity COFs. Here we demonstrate successful design synthesis a porphyrin based, 8-connected block with cubic configuration, could be further reticulated into an unprecedented interpenetrated pcb topology by imine condensation linear amine monomers. This study presents first case high-connectivity bearing nodes, thus greatly enriching topological possibilities
