The organic compounds with donor-π-bridge-acceptor type of architecture are of great interest for application as semiconductors. The synthesized compounds are obtained from 4-morpholino naphthalene-1,2-dione and 4-(4-(diethylamino) phenyl)naphthalene-1,2-dione and mono substituted ortho-phenylene diamines by condensation reaction. The donor groups are morpholinyl and N,N-diethylamino phenyl moieties, whereas acceptors are substituted phenazines. The synthesized molecules were characterized by spectral analysis.. The effect of the substitution has been studied on the basis of photophysical properties of the molecules. The halochromism behaviour of the molecule shows that at low to moderate acidity they respond differently with two types of donors. DFT computations were used in conjunction with NMR analysis to determine the ratio of the positional isomers.
具有供体-π桥-受体结构类型的有机化合物在用作半导体方面具有重大意义。这些合成化合物是由 4-吗啉基萘-1,2-二酮和 4-(4-(二乙基氨基)苯基)萘-1,2-二酮以及单取代邻苯二胺通过缩合反应得到的。供体为吗啉基和 N,N-二乙氨基苯基,受体为取代的吩嗪。合成的分子通过光谱分析进行了表征。根据分子的光物理特性研究了取代的影响。分子的卤色行为表明,在中低酸度条件下,它们对两种供体的反应是不同的。DFT 计算与 NMR 分析相结合,确定了位置异构体的比例。
