摘　　要：以3,9-苝二酰氯、双酚A、对苯二甲酰氯和间苯二甲酰氯为原料,通过相转移界面缩聚法合成了一系列苝结构单元含量不同的聚芳酯PAR-Pn(n分别为0.05%、0.10%、0.15%、0.20%,表示3,9-苝二酰氯的含量,以双酚A的物质的量为基准计算得到,下同)。通过DSC、TGA、DMA、UV-Vis及PL对材料的热稳定性、动态力学性能及光学性能进行了测试。结果表明,所制备的聚芳酯在N_(2)氛围中起始分解温度均在468℃以上,由DMA测得的玻璃化转变温度均在211℃以上,具有较高的耐热性。所有聚芳酯均具有光致发光的特性,其氯仿溶液的发射峰位于480~540 nm,且荧光强度随苝结构单元含量的增加而增强。另外,所制备的聚芳酯在常用有机试剂中均具有良好的溶解性。A series of polyarylates PAR-Pn(n is 0.05%,0.10%,0.15%and 0.20%respectively,indicating the content of 3,9-perylene diacyl chloride,calculated based on the amount of substance of bisphenol A,the same below)with different content of perylene were synthesized via interfacial condensation of perylene-3,9-dichloride,bisphenol A,isophthalic chloride and terephthaloyl chloride.The thermal stability,dynamic properties and optical properties of the polyarylates obtained were characterized by DSC,TGA,DMA,UV-Vis and PL spectra.The results showed that the initial thermal decomposition temperature and the glass transition temperature were above 468℃and 211℃,respectively,indicating high thermal stability of polyarylates.Furthermore,all the polyarylates exhibited photoluminescent characteristics with photoluminescent peaks at 480~540 nm,with the fluorescence intensity increasing with the increase of perylene content.In addition,the polyarylates showed good solubility in common organic reagents.
