Charge-transfer (CT) complexes of pyrimidine Schiff bases, derived from condensation of 2-aminopyrimidine and substituted benzaldehydes, with some aromatic polynitro compounds were prepared and investigated using IR, UV, visible and (1)H NMR spectroscopy. For all solid complexes, the main interaction between the donor and acceptor molecules takes place through the π-π* interaction. Strong and some
制备了由2-氨基嘧啶和取代的苯甲醛缩合而成的嘧啶Schiff碱与一些芳香族多硝基化合物的电荷转移(CT)配合物,并使用IR,UV,可见光和(1)H NMR光谱进行了研究。对于所有固体配合物,供体和受体分子之间的主要相互作用是通过π-π*相互作用发生的。强和弱酸性受体还通过质子从受体分子转移到电子供体的基本中心进行相互作用。此外,在某些复合物中还检测到n-π*跃迁。
