8-naphthalimide derivatives containing thiophene and pyrazole moities were synthesized by direct Pd-catalyzed C–H arylation and then characterized by 1H NMR, 13C NMR, MALDI–HRMS, and elementary analysis. The photophysical and electrochemical properties of the derivatives were also investigated. All compounds have green emission both in diluted CH2Cl2 solution and solid film. The cyclic voltammetry (CV)
通过直接Pd催化的C–H芳基化反应合成了一系列包含噻吩和吡唑基团的新型1,8-萘二甲酰亚胺衍生物,然后通过1 H NMR,13 C NMR,MALDI–HRMS和元素分析对其进行了表征。还研究了衍生物的光物理和电化学性质。所有化合物均在稀释的CH 2 Cl 2中均发出绿色光溶液和固体膜。循环伏安法(CV)测量表明目标化合物的最低未占据分子轨道(LUMO)范围为-3.49 eV至-3.29 eV,最高占据分子轨道(HOMO)范围为-6.04 eV至-5.81 eV。进行量子化学计算以获得最佳的基态几何形状以及化合物的HOMO,LUMO含量的空间分布。
