摘要
以2,5-二溴烷氧基苯为起始原料,设计并合成了以烷氧基取代苯环为核,双氰基茚满二酮为端基,噻吩或并噻吩为π桥的两个新型非共价键构象锁定型有机小分子PTIC和PTTIC,其结构和性能经^(1)H NMR,^(13)C NMR,UV,CV,DSC和GIWAXS表征。结果表明:在分子内非共价键作用力作用下,PTIC和PTTIC均表现出良好的共平面性和结晶性。
Using 2,5-dibromoalkoxybenzene as starting material,two novel noncovalent conformation locked organic small molecules PTIC and PTTIC were designed and synthesized with alkoxy substituted benzene ring as core,dicyanidinone as end group and thiophene or thienothiophene asπbridge.The structures and performances of PTIC and PTTIC were characterized by ^(1)H NMR,^(13)C NMR,UV,CV,DSC and GIWAXS.The results show that the existence of non-covalent bond forces makes the two small molecules show good coplanarity and crystallinity.
