    Switching of the Triplet Excited State of Styryl 2,6-Diiodo-Bodipy and Its Application in Acid-Activatable Singlet Oxygen Photosensitizing
    摘要:
    IodoBodipy-styrylBodipy dyads triplet photosensitizers were prepared (B-1 and B-2) which contain acid-responsive moiety. Both compounds show broadband visible light absorption, due to the resonance energy transfer (RET) between the two different visible light-harvesting Bodipy units. The photophysical properties of the dyads were studied with steady-state and nanosecond time-resolved transient absorption spectroscopy. The production of triplet excited state is switched ON or OFF by protonation/deprotonation of the amino group in the dyads. In the neutral form, the excited state is short-lived (<10 ns) and no singlet oxygen (O-1(2)) photosensitizing was observed. Upon protonation, a long-lived triplet excited state was observed (tau(T) = 3.1 mu s) and the O-1(2) quantum yield (Phi(triangle)) is up to 73.8%. The energy levels of the components of the dyads were changed upon protonation and this energy level tuning exerts significant influence on the triplet state property of the dyad. Acid-activated shuffling of the localization of the triplet excited state between two components of a dyad was observed. Furthermore, we observed a rare example that a chromophore giving shorter absorption wavelength is acting as the singlet energy acceptor in RET. The experimental results were rationalized by density functional theory (DFT) and time-dependent DFT (TDDFT) calculations.

    共振能量转移增强的罗丹明–苯乙烯基Bodipy dyad三重态光敏剂†
    摘要:
    制备了通过共振能量转移(RET)作用增强的有机三线态光敏剂(R-1和R-2)。罗丹明用作分子内能量供体,碘代-苯乙烯基-Bodipy用作分子内能量受体/自旋转换器。R-1和R-2中的能量供体和能量受体在可见光区域均具有强吸收性,但在不同的波长下(例如,对于R-1,在557 nm处ε = 120 000 M -1 cm -1,对于能量供体并且ε = 73300 M -1 cm -1对于能量受体在639 nm处)。结果,光敏剂在可见光谱区域显示宽带吸收。相比之下,传统的三重态光敏剂仅包含一种可见光收集生色团;因此,在可见光谱区域通常只有一个主要吸收带。使用稳态和时间分辨光谱,我们证明了在能量供体中的光激发之后是分子内单线态能量转移,然后通过能量受体(自旋转换器)的系统间交叉(ISC),产生了位于碘-苯乙烯基-Bodipy上的三重态激发态,这通过纳秒时间分辨的瞬态差吸收光谱法得到了证实。将有机二
