To develop efficient sensitizers for dye-sensitized solar cells(DSSCs),we recently reported doubly concerted companion(DCC)dye XW83 with a wrapped porphyrin sub-dye unit linked to an organic sub-dye unit through a flexible chain,which exhibits panchromatic absorption and excellent anti-aggregation *** further improve the absorption,we herein report XW87 and XW88 by inserting an ethynyl group into the organic sub-dye unit of XW83 near the donor and acceptor,*** the corresponding organic dyes Z3 and Z4,the introduced ethynyl group improves their absorption,but induces aggravated charge recombination,leading to lowered power conversion efficiencies(PCEs).Similar to the organic dyes,the introduced ethynyl group improves the absorption of DCC dyes XW87 and XW88 as *** addition,the ethynyl group near the acceptor of the organic sub-dye unit can be well protected by the long wrapping chains from the porphyrin *** a result,XW88 affords the highest JSC(21.84 mA/cm^(2)),V_(OC)(782 mV)and PCE(12.2%)among the DCC *** results provide an effective method for developing efficient DSSC dyes by inserting an ethynyl group at a suitable position of a DCC dye.

To develop efficient concerted companion(CC)dyes for fabricating high-performance DSSCs,three organic dyes XL1-XL3 have been designed by varying the position and number of theβ-hexylthiophene(HT)bridges,and these organic dye units are covalently linked with our previously reported porphyrin dye XW10 to construct the corresponding CC dyes *** the organic dyes,XL3 contains twoβ-hexylthiophene units at both the donor and acceptor parts and thus possesses stronger light-harvesting capability in the green light *** of the most complementary absorption between XL3 and XW10 as well as the excellent photovoltaic behavior of the individual XL3 dye,the corresponding CC dye XW76 affords the best PCE(10.78%)among all the CC *** coadsorption with CDCA,XW76 affords a highest PCE of 11.35%,which outperforms the previous cosensitization system of XW10+*** work provides an approach for developing efficient DSSCs based on CC dyes composed of an organic dye unit with suitableπspacers inserted at appropriate positions.

卟啉作为自然界的关键功能染料,在光合作用、呼吸载氧等过程中扮演着重要角色。卟啉具有独特的配位空腔和二维共轭骨架,光电性质优异,成为构建有机功能染料的重要平台。然而,常规卟啉的共轭回路为18π,近红外区的光谱响应弱,在一定程度上限制了应用拓展。为此,研究人员开发了多种在卟啉外围稠合芳环的方法,来扩展分子共轭并提升长波长区域吸收与发光。本文总结了β,β-和meso,β-两类芳香稠环卟啉的典型合成方法,对比了稠环种类、数目、方式等对长波长光谱响应的调控作用。同时,本文还简要介绍了芳香稠环卟啉在自组装、芳香性/反芳香性调控、稳定自由基、自旋电子学应用等方面的研究进展。最后,从合成与应用角度展望了芳香稠环卟啉的未来研究方向。
