摘　　要：合成了体系中含一个苯环、二个苯环的γ-取代-β二酮二羰基合铑棒状金属有机化合物,并对其介晶性进行了表征.探讨了分子长宽比、刚性实和结构对液晶性质的影响.同时表明了向列相有机液晶分子的模型设计同样能很好地指导金属有机液晶分子的设计、合成及介晶性行为的研究.Rodlike organometallic liquid crystals of γ- substituted β- diketonate dicarbonyl rhodium(Ⅰ) complexes containing one or two benzene rings were synthesized and characterized. The effects of rigid cores, structure and the ratio of molecular length to width on the liquid crystalline properties were also studied. The results show that the model design of nematic organic liquid crystal can also direct the molecular design and synthesis of organometallic liquid crystals.
