摘　　要：以简单化合物为原料,经过多步反应合成出一种新型的、带有12条肉豆蔻酰氧基取代柔性长链的卟啉配体,并通过与过渡金属盐反应,得到卟啉金属锌、铜配合物。所合成的化合物经红外光谱、紫外-可见吸收光谱、~1HNMR等进行表征。通过荧光发射光谱、荧光寿命等进行了光学性质研究,并通过差示扫描量热法和偏光显微镜研究了化合物的液晶性质。结果表明,卟啉配体与铜配合物是双变液晶,而锌配合物在升温时呈现液晶相。化合物液晶相的相变温度较低,相变区间较窄。After a series of reaction,a new porphyrin ligand and its transition metal zinc and copper complexes with 12 myristoy- loxy substituted long flexible chains were synthesized and confirmed by UV-Vis spectra,infrared spectra and 1HNMR spectra.The liquid-crystalline behaviors of these compounds were also investigated by differential scanning（DSC） and polarizing optical mi- croscopy （POM）.Research showed that porphyrin ligand and copper complex are dual variable liquid crystals,while zinc porphy- rin complex shows liquid crystalline phase when heated.The phase transition temperatures of these compounds are low and the temperature ranges of liquid crystal are narrow.
