A novel tetrabenzotriazaporphyrin (TBTAP) bearing an anchoring carboxy‐phenyl group at the meso‐carbon position (TT260) was synthesized by an efficient method, which involves the crossover condensation between phthalonitrile and aminoisoindoline precursors. Its optical and electrochemical properties were also investigated together with its use as sensitizer in dye‐sensitized solar cells (DSSCs). The performance of TT260 was compared with a benchmark molecule TT1, bearing similar bulky tert‐butyl groups at the periphery. The device, which is the first ever example of meso‐substituted TBTAP‐based DSSC, exhibits a modest maximum power conversion efficiency of 2.4±0.1 % under one‐sun conditions.

中观取代的四苯并三氮杂卟啉用于染料敏化太阳能电池

一种新颖的tetrabenzotriazaporphyrin（TBTAP）在轴承的锚固羧基-苯基基团的内消旋-碳位置（TT260）通过一种有效的方法，它涉及邻苯二甲腈和aminoisoindoline前体之间的交叉缩合合成。还研究了其光学和电化学性质，以及其在染料敏化太阳能电池（DSSC）中用作敏化剂的用途。将TT260的性能与基准分子TT1进行了比较，后者在外围带有类似的大体积叔丁基。该设备，这是介观的第一个例子在日晒条件下，基于TBTAP的已取代TBDS DSSC表现出2.4±0.1％的适度最大功率转换效率。
