(E)-(4-(2-(benzo[d]thiazol-2-yl)hydrazono)-3-methyl-2,6-diphenylpiperidin-1-yl)(phenyl)methanone [EPHDPM] and its derivatives were synthesized and characterized by FT-IR, (1)H NMR, (13)C NMR and elemental analysis. The target compound [EPHDPM] was computed using density functional theory (DFT) method. The ground-state molecular geometry and vibrational frequencies were calculated by using B3LYP/6-31G
合成了(E)-(4-(2-(2-苯并[d]噻唑-2-基)肼基)-3-甲基-2,6-二苯基哌啶-1-基)(苯基)甲酮[EPHDPM]及其衍生物并通过FT-IR,(1)H NMR,(13)C NMR和元素分析进行表征。使用密度泛函理论(DFT)方法计算目标化合物[EPHDPM]。利用B3LYP / 6-31G(d,p)的理论水平来计算基态分子的几何形状和振动频率。实验观察到的FT-IR和FT-Raman谱带被分配给分子的不同正常模式。还通过自然键轨道(NBO)分析研究了分子的稳定性和电荷离域。HOMO-LUMO能量描述了电荷在分子内发生的转移。分子静电势已被分析。已报道的EPHDPM分子具有高μβ0值,因此可用作潜在的NLO材料。计算出诸如熵和焓之类的热力学参数,并且由于振动强度的增强,这些值随着温度的升高而增加。
