含联萘基团的旋光性聚喹啉的合成与性质
Synthesis and Properties of Optically Active Polyquinolines Containing 1,1’-Binaphthyl Unit
【摘要】 由 2 ,2 -二甲氧基 -1 ,1 -联萘制备了旋光活性的 2 ,2 -二甲氧基 -6,6 -二乙酰基 -1 ,1 -联萘(DMDABN) .经元素分析 ,NRM,IR和 MS等方法对其进行结构表征 ,DMDABN与 3 ,3 -二苯甲酰基-4,4 -二氨基 -二苯基醚通过 Friedlander反应合成了旋光性聚喹啉 .所制备的聚喹啉具有较高的玻璃化转变温度 (4 74~ 5 78K)、热分解温度 (70 3~ 770 K)、很好的耐溶剂性能和较强的旋光活性
【Abstract】 Optically active 2,2\|dimethoxy\|6,6\|diacetyl\|1,1\|binaphthyl(DMDABN) was prepared from 2,2\|dimethoxy\|1,1\|binaphthyl, and its structure was comfirmed by elemental analysis, NRM, IR and MS. Optically active polyquinolines were synthesized with DMDABN and 4,4\|diamino\|3,3\|dibenzoyldiphenyl ether by Friedlander reaction. These polyquinolines showed high glass transition temperatures(474\578 K), high decomposition temperatures(703\770 K), insolubility in many common organic solvents and strong chiral activity.
