PROBLEM TO BE SOLVED: To provide a two-photon absorption material which has a sufficient two-photon absorption characteristics. SOLUTION: This is a two-photon absorption material, using a compound whose structure, is a polymer made by connecting porphyrin frames at least at two positions directly or via another unit. In this polymer molecule, the angle of two adjoining porphyrin surfaces is controlled to 10-80°on the average. COPYRIGHT: (C)2006,JPO&NCIPI |
