     View Summary

    光安定性に問題があるUV-A吸収分子であるブチルメトキシジベンゾイルメタン(BMDBM)からUV-B吸収分子であるオクチルメトキシケイ皮酸エステル(OMC),2-ethylhexyl 2-cyano-3,3-diphenylacrylate(OCR)および新規UV-B吸収分子dioctyl 4-methoxybenzylidenemalonate(DOMBM)への三重項-三重項エネルギー移動速度定数,kT–T,をパルス励起時間分解りん光の実験により評価した。その結果,kT–T (BMDBM–DOMBM) > kT–T (BMDBM–OMC) ≥ kT–T (BMDBM–OCR),すなわち,DOMBMへのエネルギー移動速度定数が最も大きいことが判明した。
