【摘要】：设计并合成了一种以偶氮基呋喃(EFNFC)为共轭桥结构的新型生色团分子,将这种分子分别与乙烯基呋喃(EFFC)和偶氮基苯(EFNC)的分子进行对比.通过对这三种生色团的光学性能和热性能对比研究,发现EFNFC生色团分子在DMSO中的最大吸收波长λmax=573 nm,透光性比EFFC更好,但稍弱于EFNC;EFNFC通过溶致变色法实际测试得到的μgβ1064nm值为4.479×10~(-49) esu,比EFFC有所提升,但略低于EFNC分子;三种分子的热稳定性均较好,5%热失重温度(Td)值均在250℃以上,其中EFNFC的Td值最高,达到270℃.
[Abstract]:A novel chromophore molecule with azo furan (EFNFC) as conjugate bridge was designed and synthesized. The molecule was compared with that of vinyl furan (EFFC) and azobenzene (EFNC), respectively. By comparing the optical and thermal properties of the three chromophore groups, it is found that the maximum absorption wavelength 位 max=573 nm of EFNFC chromophore molecules in DMSO is better than that of EFFC. The 渭 g 尾 1064nm value obtained by discoloration method was 4.479 脳 10 ~ (-1) -49) Eu, which was higher than that of EFFC, but slightly lower than that of EFNC, and the thermal stability of the three kinds of molecules were all above 250 鈩，
