Microporous porphyrin and metalloporphyrin materials

The diverse efforts to rationally construct microporous solids using porphy rins and metalloporphyrins as molecular building blocks are reviewed. Porph yrin-based molecular crystals, hydrogen-bonded networks, and metal ion coor dination polymer networks are examined in detail. Recurring geometrical mot ifs observed in the structural frameworks of different porphyrinic solids a re emphasized, and the influences of solvates and guest molecules are explo red. Attempts to construct porphyrin-siloxane networks are also reviewed. ( C) 2000 Academic Press.
