The photofading of 6'-nitroquinophthalone was accelerated in the presence of sensitizer of singlet oxygen, e.g. Rose Bengal, and retarded by adding effective singlet oxygen quencher, such as nickel (II) chloride. That of 8'-nitroquinophthalone was accelerated in the presence of sensitizer of singlet oxygen and retarded by adding singlet oxygen quencher similar to 6'- nitro-delivertive, and also retarded by adding radical scavenger, e. g. 2, 6-di-t-butylphenol. It is suggested that the photofading of 6-nitroquinophthalone delivertive in solution may be due to a self-sensitized photo-oxidation involving singlet oxygen and in the case of 8-nitro-delivertive, may be due to both self-sensitized photo-oxidation involving singlet oxygen and specific intramolecular redox reaction."}, pages = {147--152}, title = {染料の光退色 : キノフタロンの光退色におよぼす置換基の影響}, volume = {28}, year = {1982} }
