| 摘 要： | 1968年,Becker和Kolc合成出第一个吲哚啉螺苯井噻喃以及在77 K下观察到它的光致变色现象以后,一系列螺噻喃化合物的合成及性能研究工作相继报道。这些研究表明,螺噻喃化合物在溶液和高分子介质中,光致变色开环体的最大吸收一般都在600～800nm之间。而且,当螺噻喃化合物中苯并噻喃环上6位引入硝基后,室温下就能够观察到开环体的

| Abstract: | Seven new indolinospirobenzothiopyrans with 1'-long chain alkyl group substi-tutions have been synthesized. Their melting points, elemental analyses, ~1H NMR and MSspectra are studied to identify the structure of these new compounds. The photochromic pro-perties of all these compounds in solution and polymer media. as well as the absorptionspectral properties of the title compounds and their ring opened form (merocyanines) arestudied. The effects of the substituent and media on the spectral properties and the stabilityof merocyanines are also discussed. |
