以对-溴甲苯、对苯二酚、1-溴己烷、1,4-对苯二异氰酸酯等为原料,通过Williamson反应、溴化反应、格氏反应、氧化反应、Suzuki反应等一系列反应合成了用于合成梯形聚合物的两种重要单体:2,5-二[4'-N-(1,1-二羟甲基)丙胺基甲酰苯基]-1,4二己氧基苯和2,5-二{4'-N-[1,1-二(对异氰酸酯基苯胺甲酸酯基)丙胺基甲酰苯基]}-1,4二己氧基苯,并利用元素分析、红外光谱(IR)、核磁共振氢谱(1HNMR)和质谱(MS)等手段对其进行了结构表征.
As important monomers for preparation of ladder-like polymers, two new types of structurally ordered ladder-like compounds, 2,5-his [ 4'-N- ( 1,1-dihydroxylmethyl ) -propylamidocyanogen-methylaeylphenyl]-1, 4-bishexyloxybenzen ( M1 ) and 2, 5-bis-{ 4'-N-[ 1, 1-bis ( 4-isocyanatephenylamidocyanogenformylester)propylamidocyanogen-methylacylphenyl] }-1,4-bishexyloxybenzene(M2), were synthesized by a series of reactions such as Williamson reaction, bromination reaction, Grignard reaction, oxidation reaction, and Suzuki coupling reaction with p-bromotoluene, 1,4-hydroquinone, 1-bromohexane, toluene diisoeyanate etc. as starting materials. The compositions and structures of M1 and M2 were characterized via elemental analysis, infrared resonance (IR) spectroscopy, proton nuclear resonance ( 1H NMR) and mass (MS) spectroscopy.
