Control of Molecular Orientation and Arrangement of Fluorescent Dyes and Development of Colorful Dye-Sensitized Solar Cells(DSSCs)

作为一类新的给体-π-受体(D.π。A)染料敏化太阳能电池（dye - sensitized Solar Cells, DSSCs）的染料敏化剂，我们设计并合成了一系列的D.π。一种荧光染料，在发色团骨架的不同位置上含有羧基或以吡啶环吸电子。注射锚固组。在实验结果和MO计算的基础上，我们提出，为了开发高性能的DSSCs，有必要创建一个时代。使得分子设计不仅能够控制染料本身的光物理和电化学性能，还能够控制染料在TiO2表面的分子排列和/或取向，从而在染料和TiO2电极之间提供良好的电子通信。

As a new class of donor-π-acceptor(D.π. A) dye sensitizers for Dye-Sensitized Solar Cells(DSSCs), we have designed and synthesized a series of D.π. A fluorescent dyes with carboxyl groups on different positions of a chromophore skeleton or with pyridine ring as electron-withdrawing. injecting anchoring group. On the basis of experimental results and MO calculations, we propose that, for developing high performance DSSCs, it is necessary to create an epoch. making molecular design capable of controlling not only photophysical and electrochemical properties of the dyes themselves but also molecular arrangement and/ or orientation of the dyes on TiO2 surface to provide a good electron communication between the dyes and TiO2 electrode.
