摘要
用邻烷氧基苯甲醛与吡咯缩合合成meso-四(邻烷氧基苯基)卟啉,再与醋酸锌配合反应合成了meso-四(邻烷氧基苯基)卟啉合锌配合物10个,其中未见文献报道的配合物9个,得到该系列配合物的晶体或固体.用1HNMR,MS,IR,UV,元素分析等表征确证了该系列配合物的结构.用差示扫描量热法和偏光显微镜研究了该系列配合物的液晶性能,发现6个配合物具有液晶性,其液晶行为表现为升温单变液晶.
meso-Tetrakis（2-alkoxyphenyl）porphyrin [meso-T（2-ROP）PH2] obtained by condensation of 2-alkoxybenzaldehydes with pyrrole, reacted with zinc acetate to form corresponding complexes [meso-T（2-ROP）PZn], while nine of them were new compounds. For the first time, meso-T（2-ROP）PZn were generated as crystals or solids. Molecular structures of all synthesized compounds were confirmed by IR, UV, ^1H NMR, MS spectra and elemental analysis. Differential scanning calorimetry and polarizing microscope were used to probe the liquid crystal properties of the serial complexes. Six of them were found to exhibit liquid crystal properties. However they displayed as heated monotropic liquid crystals.
