  Optimizing the photochromic performance of naphthopyrans in a rigid host matrix using poly(dimethylsiloxane) conjugation

  摘要：

  一系列甲氧基取代的2,2-二芳基-2H-萘并吡喃光致变色染料被合成并通过引入羟基功能性，以便随后将其固定到柔性的聚二甲基硅氧烷低聚物中。研究了生成的PDMS-萘并吡喃共轭物在热固性基质中的光致变色性能，并与非共轭、电子等效的对照染料进行了比较。发现着色和褪色的速度都大幅提高，关键的褪色半衰期T1/2减少了42-80%。PDMS共轭在刚性基质中提供的类似溶液性能的程度，参考了对照染料在溶液中的褪色性能进行了考察，发现范围从20%到90%不等。这些测量结果被认为受到光致变色染料的电子性质和立体相互作用的影响。

  A series of methoxy substituted 2,2-diaryl-2H-naphthopyran photochromic dyes were assembled incorporating hydroxy functionality to allow their subsequent attachment to flexible poly(dimethylsiloxane) oligomers. The photochromic performance of the generated PDMS–naphthopyran conjugates was studied in a thermoset host matrix and compared to non-conjugated, electronically equivalent control dyes. Both coloration and decoloration speeds were found to be greatly improved with critical T1/2 decoloration times reduced by 42–80%. The extent of solution-like performance provided by PDMS conjugation in the rigid host was examined with reference to the fade performance of control dyes in solution, and found to range from 20 to 90%. These measures are believed to be influenced by the electronic nature and steric interactions of the photochromic dyes.
