最近,二芳基苯 (DAB) 已被开发为一个新的 T 型光致变色分子家族。在这项工作中,我们新设计并合成了 DAB,用于创建具有高光反应性和快速热反应性的分子。利用分子内 CH-N 氢键和活性碳上的庞大取代基导致光反应性增强和热回反应速率加快。此外,我们证明即使在较低浓度下,与先前报道的 DAB 相比,高光反应性也能产生更好的着色。这些结果不仅为分子设计提供了一种策略,而且对于开发环境负荷较小的材料也很有用。

The present invention provides a carbostyril compound represented by General Formula (1)
or a salt thereof, wherein A is a direct bond, a lower alkylene group, or a lower alkylidene group; X is an oxygen atom or a sulfur atom; R
4
and R
5
each represent a hydrogen atom; the bond between the 3 and 4 positions of the carbostyril skeleton is a single bond or a double bond; R
1
is a hydrogen atom, etc; R
2
is a hydrogen atom, etc; and R
3
is a hydrogen atom, etc. The carbostyril compound or salt thereof of the present invention induces the production of TFF, and thus is usable for the treatment and/or prevention of disorders such as alimentary tract diseases, oral diseases, upper respiratory tract diseases, respiratory tract diseases, eye diseases, cancers, and wounds.
