A new series of aromatic cyanovinyl compounds were synthesized via one-pot reactions of tri- or tetracyanoethylenes with nucleophilic reagents. The ground-state geometries and UV–vis absorption spectra of the compounds were computationally analyzed by means of density functional theory (DFT) and time-dependent density functional theory (TDDFT) calculations, respectively. None of the compounds were
通过三或四氰基乙烯与亲核试剂的一锅反应,合成了一系列新的芳族氰基乙烯基化合物。分别通过密度泛函理论(DFT)和时变密度泛函理论(TDDFT)计算对化合物的基态几何形状和UV-vis吸收光谱进行了计算分析。这些化合物在溶液中均不发荧光,但有些在固态时显示出强烈的发射。使用完整的活性空间SCF(CASSCF)计算化合物探索了第一激发单重态(S 1)势能面(PES),以阐明考虑了圆锥形交叉点(CI)的非辐射衰变机理。
