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℃. A novel chromophore molecule with the conjugate bridge of azo furan (EFNFC) was designed and synthesized. The molecules were compared with the molecules of vinyl furan (EFFC) and azo benzene (EFNC) respectively By comparing the optical properties and thermal properties of the three chromophores, we found that the maximum absorption wavelength λmax of the EFNFC chromophore in DMSO is 573 nm, which is better than that of EFFC but slightly weaker than that of EFNC. The value of μgβ1064nm was 4.479 × 10 ~ (-49) esu, which was slightly higher than that of EFFC, but slightly lower than that of EFNC. The thermal stability of the three molecules were good, and 5% of the heat Weight loss temperature (Td) values ​​?? are above 250 ℃, which EFNFC highest Td, reaching 270 ℃.
