Zinc…nitro recognition is used as a tool to generate porous coordination polymers based on 44 networks and dinitrophenyl substituted porphyrin molecules. These polymers are soluble in organic solvents and show high selectivity for the inclusion of aromatic guests. The relative weakness of the zinc…nitro recognition enabled the modification of network structure by the incorporation of ligands that have higher binding affinity for zinc. Use of ditopic ligands led to the formation of porphyrin dimers some of which have the octupolar charge distribution with potential as nonlinear optical materials. The crystal design principles used in the selection of materials, their synthesis, crystal structures and thermal properties are described in this presentation.
