A new porphyrin-perinaphthothioindigo composite, where porphyrin and perinaphthothioindigo dye are connected though a triple bond, was synthesized. In UV-vis absorption spectra of the composite, absorption originating from the trans-isomer appeared at 655

A porphyrin-perinaphthothioindigo conjugate having two-photon absorption cross-sections of ～2000 GM and ～700 GM for trans- and cis-isomers, respectively, was synthesized and exhibited clear photochromic behavior upon one-photon and two-photon excitation.

Compounds that are suitable to be used for three-dimensional optical recording materials, etc. The compounds each have a structure that allows pi-electron conjugation to be achieved by linking a porphyrin ring and a perinaphthothioindigo ring to each other with a straight-chain atomic group. The compounds of the present invention are suitable to be used for three-dimensional optical recording materials, etc. since they have a high two-photon absorption efficiency and undergo photochromism effectively through optical absorption.
