Abstract

L'invention a pour but de pourvoir à un procédé propre et efficace de fabrication d'un complexe métallique d'un composé qui a un squelette de porphyrine, qui n'utilise pas du tout de solvant organique pendant la synthèse et est apte à séparer facilement un complexe métallique dans un état solide à partir d'une solution aqueuse d'un sel métallique après la réaction, et qui place un fardeau extrêmement petit sur l'environnement. A cet effet, selon l'invention, le problème décrit ci-dessus est résolu par un procédé de fabrication d'un complexe métallique d'un composé qui a un squelette de porphyrine, dans lequel un composé ayant un squelette de porphyrine et un sel métallique sont amenés à réagir l'un avec l'autre dans l'eau à une température de réaction de 200-450˚C (inclus). On préfère que la tétraphénylporphyrine et un sel métallique soient amenés à réagir l'un avec l'autre dans l'eau à une température de réaction de 300-400˚C (inclus).
