SOLVATOCHROMIC DYE COMPOSED OF COMPOSITE OF PORPHYRIN COMPOUND AND PHYLLOSILICATE

摘要

PROBLEM TO BE SOLVED: To provide a solvatochromic dye which has sufficient durability and can be simply repeatedly used. SOLUTION: The solvatochromic dye is composed of a composite obtained by intercalating a porphyrin compound into the layers of a phyllosilicate. Preferably, the porphyrin compound is a solvatochromic dye of a cationic porphyrin or a cationic metalloporphyrin. COPYRIGHT: (C)2007,JPO&INPIT
