Abstract：A acid-controlable triplet photosensetizer (BR-1) enhanced with the fluorescence resonance energy transfer (FRET) effect was prepared. Rhodamine was used as an intramolecular energy donor as well as acid-controlable unit, and iodo-styryl-Bodipy was used as an intramolecular energy acceptor/spin converter. The intramolecular energy transfer from open-formed Rhodamine unit to iodo-styryl-Bodipy unit was studied upon the addition of acid (trifluoroacetic acid, TFA) at different time. The fluorescence quenching and excitation spectra indicated that the FRET efficiency is significantly enhanced from 0.0% to 56.1%. Our results are useful to design the triplet photosensitizers with controlable triplet state property .

摘要：本文合成了基于共振能量转移机理调控的三重态光敏剂BR-1。罗丹明作为分子内的能量给体，同时作为酸控基团。碘化氟硼吡咯衍生物作为分子内能量受体和自旋转换单元。在加入酸（三氟乙酸）后，我们研究了从开环罗丹明到氟硼吡咯染料的分子内共振能量转移。通过对荧光发射光谱和激发光谱的测试，得出共振能量转移效率可以明显的从0.0%增加到56.1%。这对将来设计新型的具有可控性质的三重态光敏剂有着重要意义。
