【摘要】：設(shè)計并合成了一種以偶氮基呋喃(EFNFC)為共軛橋結(jié)構(gòu)的新型生色團分子,將這種分子分別與乙烯基呋喃(EFFC)和偶氮基苯(EFNC)的分子進行對比.通過對這三種生色團的光學性能和熱性能對比研究,發(fā)現(xiàn)EFNFC生色團分子在DMSO中的最大吸收波長λmax=573 nm,透光性比EFFC更好,但稍弱于EFNC;EFNFC通過溶致變色法實際測試得到的μgβ1064nm值為4.479×10~(-49) esu,比EFFC有所提升,但略低于EFNC分子;三種分子的熱穩(wěn)定性均較好,5%熱失重溫度(Td)值均在250℃以上,其中EFNFC的Td值最高,達到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，
