基于Suzuki偶合反应合成新型9-取代基N-正辛基-苝-3,4-二羧酸单酰亚胺衍生物：9-苯基-N-正辛基-苝-3,4-二羧酸单酰亚胺（C1）,9-（4-甲氧基苯基）-N-正辛基-苝-3,4-二羧酸单酰亚胺（C2）,9-{4-（二苯基胺基）苯基}-N-正辛基-苝-3,4-二羧酸单酰亚胺（C3）,对化合物分子结构进行表征,用紫外可见（UV-Vis）光谱、荧光（PL）光谱研究其光化学性质;在典型溶剂乙酸乙酯中,目标化合物的紫外最大吸收波长（λmaxabs）在490~550nm,相比于C1,化合物C2,C3最大吸收波长都红移了;在典型溶剂乙酸乙酯中,荧光最大发射波长（λmaxf）在525~625nm,与C1相比,化合物C2,C3的荧光最大发射波长（λmaxf）也发生了红移。

Three novel perylene monoimide derivatives, i. e. 9-phenyl-N-octyl-perylene-3,4-dicarb-oximide （C1）, 9-（4-methoxyphenyl）-N-oetyl-perylene-3,4-dicarboximide （C2） and 9-（N, NCdiphenylaminophenyl）- N-Octyl-perylene-3,4-dicarboximide （C3）are synthesized via Suzuki coupling reaction. Their structures are effectively characterized via hydrogen nuclear magnetic resonance（NMR）,while their optical properties are investigated by ultraviolet-visible spectroscopy （UV-Vis）and fluorescence spectrum（PL）. It＇s found that the UV-Vis maximum absorptionO, （λabs max）of the three studied compounds in ethyl acetate ranges from 490 nm to 550 nm,and compared with Cl,the maximum absorptions of compounds C2 and C3 show red shift. While,their maximum emissions （λfmax）range from 525 nm to 625 nm in ethyl acetate,and compared with C1 ,the maximum emissions （λfmax）of compounds C2 and C3 also show red shift.
