The synthesis of 1,10-dihydroxyperylene bisimides by nucleophilic substitution of brominated perylene bisimide is described. 1,10-Dihydroxyperylene bisimides formed J aggregates in nonpolar solvents and showed a clearly redshifted absorption band. The solvent polarity also influenced the hydrogen bond with the hydroxyl group, and thus, the photophysical properties of perylene bisimide. The photophysical properties of these dihydroxyperylene perylene bisimides can also be tuned by changing charge transfer from the hydroxyl groups to the perylene core through the introduction of metal ions.
本文描述了通过溴代苝二酰亚胺的亲核取代合成 1,10-二羟基苝二酰亚胺。1,10-二羟基苝二酰亚胺在非极性溶剂中形成 J 聚集体，表现出明显红移的吸收带。溶剂极性也影响与羟基的氢键，从而影响苝二酰亚胺的光物理性质。通过引入金属离子，从羟基到苝核的电荷转移可以调节这些二羟基苝二酰亚胺的光物理性质。
