Supramolecular materials with robust and tunable channels constructed from tin (IV) porphyrin phenolates

Three robust molecular porous materials (MPMs) constructed from Sn (IV) TTP (bisphenolates) were reported. They all possess 1D hourglass-shaped channels within their crystal structures. Functionalisation of the channel lining through judicial choice of substituted phenol was demonstrated, which also allowed for a change in the pore diameter. TGA investigations revealed that these novel supramolecular systems are thermally stable over 550 K.
