摘　　要：用分子激子理论分析了分子间及分子内酞菁二聚体中发色团的距离和相对取向,说明了乙烷的1,2位被酞菁取代后,在溶液中的构象接近顺式.表明非链相互作用可克服空间阻碍导致有序结构形成.The relative orientation and distance between phthalocyanine chromophores linked by carbon chain were analyzed by the molecular exciton theory. It was shown that the predominant relative orientation of ethylene substituted by phthalocyanine at 1,2 position is similar to trans-conformation. Thus the non-bonding interaction between chromophores may induce th formation of ordered structure.
