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
