work, the syntheses and characterization of four new TPA-BODIPY dyads as hole-transporting layers (HTLs) are reported. The photophysical and electrochemical properties of the dyads BTPA-I, BTPA-II, BTPA-III and BTPA-IV are investigated in solution and compared with the reference compounds BDP, BDP1, BDP2, TPA, A (triphenylamine) and B (4,4′-dimethoxitriphenylamine). The TPA-BODIPY derivatives strongly
在这项工作中,报道了作为空穴传输层(HTL)的四个新的TPA-BODIPY二元化合物的合成和表征。在溶液中研究了二联体BTPA-I,BTPA-II,BTPA-III和BTPA-IV的光物理和电化学性质,并与参考化合物BDP,BDP1,BDP2,TPA,A(三苯胺)和B进行了比较。(4,4'-二甲氧基三苯胺)。TPA-BODIPY衍生物强烈吸收可见光,并且在BODIPY单元上进行光激发后,这些二重化合物进行光诱导的电子转移,形成相应的电荷分离物,这通过荧光的溶剂化变色法得到了证实。它们的氧化还原电势和光物理性质表明,新的BTPAs衍生物显示出比释放三苯胺更好的电离势,这使其有希望用作空穴传输层(HTL)。
