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.

hioindigo composite in which two porphyrins are connected to a perinaphthothioindigo dye through ethynyl linkages. The UV-vis absorption spectra of the composite showed an absorption peak originating from the trans-isomer at around 730 nm. Upon photoirradiation at 760 nm, the intensity of this absorption decreased with increasing absorption of the cis-isomer around 500 nm. The HOMO–LUMO absorption
