  • Optimizing the photochromic performance of naphthopyrans in a rigid host matrix using poly(dimethylsiloxane) conjugation
    作者:Francesca Ercole、Nino Malic、Thomas P. Davis、Richard A. Evans

    日期:——
    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.
    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。

  • Modulation of the fading kinetics of lactone-fused naphthopyran UV photoswitches
    作者:Vânia Graça、Céu Sousa、Paulo J. Coelho
    DOI:10.1016/j.dyepig.2022.110301
    日期:2022.6
    A set of new lactone-fused naphthopyrans substituted with aryl or arylethynyl groups were synthesized using an acid-catalyzed one-pot reaction. These colorless dyes exhibit photochromic activity at 20 °C acquiring intense reddish hues under UV light, that fades completely, in the dark within a few minutes. The introduction of the arylethynyl group increases the thermal stability of the reddish photoisomers

  • Joining High Coloration and Fast Color Fading with Photochromic Fused-Naphthopyrans
    作者:Céu M. Sousa、Paulo J. Coelho
    DOI:10.1002/ejoc.201901814
    日期:2020.2.28
    An easy synthesis of photochromic naphthopyrans with a fused lactone ring is described. UV irradiation of these uncolored compounds, in solution or dispersed in polymeric materials, provide a single photoisomer with an intense orange coloration that returns completely to the initial uncolored state in less than 2 min at room temperature.

  • Synthesis of Photochromic Heterocyclic-Fused Naphthopyrans. Tuning the Color and Fading Speed

    DOI:10.1246/bcsj.20230057
    日期:2023.7.15
    Abstract

    New photochromic 3-thienyl-3H-naphtho[1,2-b]pyrans fused to lactone and indole rings were efficiently prepared using a one-pot acid-catalyzed reaction, at room temperature, as the key step. These colorless photoswitches acquire intense red/brown shades under UV light and return spontaneously to the colorless state in the dark. The combination of the 3 heterocyclic rings assures a broad and intense absorption in the visible region and it allows a full switch between the two states in less than 1 min, at room temperature.

    摘要 以室温下的单锅酸催化反应为关键步骤,高效地制备了与内酯和吲哚环融合的新型光致变色 3-噻吩基-3H-萘并[1,2-b]吡喃。这些无色光开关在紫外光下会呈现强烈的红色/棕色,在黑暗中会自发恢复到无色状态。3 个杂环的组合确保了它们在可见光区域具有广泛而强烈的吸收,并能在室温下不到 1 分钟的时间内实现两种状态的完全切换。
