Ten subphthalocyanine triimides (SubPcTI) with different substituents at imide sites and B atoms were designed and synthesized. These compounds with low-lying lowest unoccupied molecular orbital energy levels (from -3.91 to -3.98 eV), strong absorption in the range of 450-650 nm, and adjustable solubility are expected to be excellent electron acceptors. Non-fullerene bulk heterojunction organic solar cells based on acceptor 8c showed power conversion efficiency of 4.92%, which is the highest value among subphthalocyanine derivatives.
设计并合成了十种在酰亚胺位点和硼原子处具有不同取代基的亚酞菁三酰亚胺（SubPcTI）。这些化合物具有较低的最低未占据分子轨道能级（-3.91至-3.98电子伏特）、在450-650纳米范围内有强吸收且溶解性可调节，有望成为优异的电子受体。基于受体8c的非富勒烯本体异质结有机太阳能电池的功率转换效率为4.92%，这是亚酞菁衍生物中的最高值。
