Three small molecule organic compounds based on conjugated acetylene-linked methoxy triphenylamine terminal groups with different substituted thiophene cores were synthesized and firstly applied as hole-transporting materials (HTMs). The electron-deficient acetylene linkers can tune the energy levels of frontier molecular orbitals. The physical property measurements show that the HTMs (, and ) possess good stability, hydrophobicity, and film-forming ability. Further, the HTMs were applied in the MAPbI-based perovskite solar cells (PSCs), and the best power conversion efficiency (PCE) of 6.04%, 6.77%, and 6.48% was achieved, respectively, which implies that they exhibit great potential in photovoltaic applications.
基于共轭乙炔连接的甲氧基三苯胺末端基团和不同取代噻吩核心的三种小分子有机化合物被合成出来，并首次用作空穴传输材料（HTMs）。缺电子的乙炔连接体可以调节前沿分子轨道的能级。物理性质测量表明，HTMs（，和）具有良好的稳定性、疏水性和成膜能力。此外，HTMs 被应用于基于 MAPbI 的钙钛矿太阳能电池（PSCs）中，分别实现了 6.04%、6.77%和 6.48%的最佳功率转换效率（PCE），这表明它们在光伏应用中具有巨大的潜力。
