PURPOSE:To prevent the attack of radicals, and to obtain optical bleaching resistance by inserting a dithiolate complex group pigment among bases in deoxyribonucleic acid DNA and forming a dithiolate complex group pigment/DNA complex. CONSTITUTION:A dithiolate complex/deoxyribonucleic acid complex, in which a dithiolate complex group pigment is inserted among base pairs in deoxyribonucleic acid, or a dithiolate complex group pigment/caffeine complex having sandwich structure in which the dithiolate group pigment is held among caffiene of two molecules is used. Consequently, the attack of radicals can be prevented. The attack of radicals will be obviated for the reason that the dithiolate complex group pigment 2 is probably inserted between base pairs 3 (A represents adenine, C cytosine, G guanine, T thymine and 1 a nucleic acid phosphoric acid group) arranged in parallel and a radical generating agent cannot easily approach to the dithiolate complex group pigment 2 in the dithiolate complex group pigment/DNA complex. |
