  有机三重态敏化剂库，其衍生自具有长寿命三重态激发态的单发色团（BODIPY），用于基于三重态-三重态An灭的上转换

  摘要：

  基于三重态-三重态an灭（TTA）的上转换很有吸引力，因为它们易于调节的激发/发射波长，低激发功率密度和高上转换量子产率。对于TTA上转换，将三重态敏化剂和受体结合起来以收集辐射能，并通过三重态-三重态能量转移（TTET）和TTA工艺获得更高能量的发射。目前，三重态敏化剂仅限于磷光过渡金属络合物，因为它们的UV-vis吸收和T 1的调节激发态的能级很困难。在此，我们首次提出了基于硼二吡咯亚甲基（BODIPY）单一生色团的有机三重态敏化剂库。有机增敏剂在510-629 nm（ε高达180,000 M –1 cm –1）下表现出强烈的UV-vis吸收。长寿命的三线态激发态（τ Ť高达66.3微秒）在所述敏化剂的激发被填充，通过纳秒时间分辨瞬态差吸收光谱和DFT计算证明。与苝或1-氯-9,10-双（苯基乙炔基）蒽（1CBPEA）作为三重态受体，显著上变频（Φ UC对于溶液样品和聚合物薄膜，观察到高达6

• Switching of the Triplet Excited State of Styryl 2,6-Diiodo-Bodipy and Its Application in Acid-Activatable Singlet Oxygen Photosensitizing

  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.
