A series of polyaromatic hydrocarbons with anthracene, phenanthrene and pyrene units connected with Schiff base junctions were synthesized via condensation of p-phenylenediamine and hydrazine with selected aldehydes. The effect of both hydrocarbon structures and presence of N-N- or phenyl- linked diimines on properties of the prepared azines and azomethines was analyzed. The obtained compounds were soluble in common organic solvents and melted in the range of 226-317°C. Their photophysical and electrochemical properties were investigated by UV-vis, photoluminescence spectroscopies and cyclic voltammetry (CV), respectively. Moreover, a density functional theory (DFT) was applied for calculation of their electronic and geometric structures as well as absorption and emission spectra. Additionally, their electron acceptor activity was preliminary tested in photovoltaic experiment.
通过对苯二胺和肼与选定醛的缩合反应，合成了一系列具有蒽、菲和芘单元并通过席夫碱连接的多环芳烃。分析了烃结构以及N-N-或苯基连接的二亚胺的存在对所制备的嗪和偶氮甲碱性质的影响。所得到的化合物可溶于常见有机溶剂，熔点在226 - 317°C范围内。分别通过紫外可见光谱、光致发光光谱和循环伏安法（CV）研究了它们的光物理和电化学性质。此外，应用密度泛函理论（DFT）计算它们的电子和几何结构以及吸收和发射光谱。另外，在光伏实验中对它们的电子受体活性进行了初步测试。
