Soluble phthalocyanine tetraimides (PcTIs) with hydrophobic side chains were designed and synthesized via three routes. Their absorption, fluorescence, electrochemistry, stability, charge mobility, and geometries were investigated. These planar conjugation compounds with intense absorption in 550–850 nm, deep lowest unoccupied molecular orbitals of −3.92 to −3.98 eV, decomposition temperature higher
设计并通过三种途径合成了具有疏水性侧链的可溶性酞菁四酰亚胺(PcTIs)。研究了它们的吸收,荧光,电化学,稳定性,电荷迁移率和几何形状。这些平面共轭化合物具有在550-850 nm处的强烈吸收,-3.92至-3.98 eV的最深最低未占据分子轨道,高于400°C的分解温度和最高4.88×10 -4 cm 2 V -1 s的电子迁移率-1(SCLC)是出色的溶液可处理受体。基于受体CuPcTI-C11的块状异质结太阳能电池的功率转换效率为1.17%,是酞菁衍生物中的最高值。
