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.
适用于用作三维光学记录材料等的化合物。这些化合物的结构通过直链原子团将
卟啉环和周
萘并
噻吩吲哚环相互连接,从而实现π电子共轭。由于这些化合物具有高的双光子吸收效率和通过光学吸收有效进行光致变色,因此它们适合用作三维光学记录材料等。
