Panchromatic RuII sensitizers TF‐30–TF‐33 bearing a new class of 6‐quinolin‐8‐yl‐2,2′‐bipyridine anchor were synthesized and tested under AM1.5 G simulated solar irradiation. Their increased π conjugation relative to that of the traditional 2,2′:6′,2′′‐terpyridine‐based anchor led to a remarkable improvement in absorptivity across the whole UV–Vis–NIR spectral regime. Furthermore, the introduction
合成了带有新型6-喹啉-8-基-2-2,2'-联吡啶锚的全色Ru II增感剂TF-30-TF-33,并在AM1.5 G模拟太阳辐射下进行了测试。相对于传统的基于2,2':6',2''-吡啶的锚,它们增加的π共轭导致整个UV-Vis-NIR光谱范围内的吸收率显着提高。此外,在喹啉基片段上引入大体积的叔丁基取代基,不仅 由于抑制了染料聚集而导致J SC值增加,而且显着也没有导致V OC损失与含有三羧基吡啶的锚定剂的参比敏化剂相比。在DSC装置中的敏化剂冠军被发现是TF-32的性能Ĵ SC =19.2毫安厘米-2,V OC = 740毫伏,FF = 0.72,和η = 10.19%。因此,这种6-喹啉-8-8基-2,2'-联吡啶锚钉可作为带有任何三齿附属物的下一代Ru II敏化剂的原型。
