PROBLEM TO BE SOLVED: To provide a compound useful as an optically functional material making the best use of porphyrin characteristics. SOLUTION: The compound is composed of a dendrimer structure with porphyrins expanded in a three-dimensional manner, for example, being a wheel-shaped multiporphyrin dendrimer compound of the formula[wherein, n is an integer of 1-10(preferably 1-3); X is e.g. an ester linkage; Z is e.g. a benzyl ether linkage; Y is e.g. H; and M is e.g. a zinc atom]. This compound has very high light-absorbing ability in the visible light region and also exhibits high solubility to organic solvents. COPYRIGHT: (C)2006,JPO&NCIPI
