Recent advances in the synthesis of covalently linked multiporphyrin arrays are summarized with particular emphasis on those with well-defined geometries and with novel and interesting properties. Of these, 1) aromatic-group bridged porphyrin arrays have been proved to be useful for defining geometries of the porphyrin arrays without alternation of physical properties of porphyrin subunits, 2) ethynyl-group bridged porphyrin arrays that are relatively easy to make by palladium-catalyzed reactions display significant changes in their optical and electrochemical properties particularly when the ethynyl groups are attached at the meso-positions of porphyrins, and 3) meso-meso linked multiporphyrin arrays are promising in view of their unique optical properties, easy extension to higher oligomers, and relatively high solubility.
