利用一步酯化法并进一步通过重结晶纯化法成功地合成了含螺吡喃基团的丁二炔衍生物,并对其进行了
1
H NMR、质谱、元素分析、DSC、TGA和红外表征。测试结果表明,样品的熔点为55℃,具有较好的热稳定性,直到282℃才开始分解。接着对样品进行了光学测试,紫外光谱表明,经254 nm紫外光照射后,其最大吸收峰大约位于564 nm。荧光光谱表明,其最大荧光发射波长位于大约650 nm。化合物膜的耐疲劳测试表明,样品具有很好的耐疲劳性。
The spiropyran functionalized diacetylene derivative was prepared by esterification reaction between 10
12-pentacosadiynoic acid and 3'
3'-Dimethyl-6-nitro-spiro[2H-1-benzopyran-2
2'-indoline]-1'-ethanol. Then
it was purified
via
recrystallization and characterized through

IR. The results show that the melt point of the sample is 55℃. It has good thermal stability and begins to decompose until to 282℃. The absorption spectrum shows only one absorption peak (
max
=564 nm) irradiated by UV light (
=254 nm). The fluorescence spectra indicate the fluorescence peak position is at about 650 nm when the excitation light wavelength varying from 560 to 580 nm. The photoreaction reversibility of the target compound doped in PMMA film is detected
and the results confirm that it has good fatigue resistance.
