可见或近红外（NIR）光响应的快速光开关分子用于实时、非接触地控制物理和化学性质的发展由于对材料和生物组织的非侵入性特征而受到越来越多的关注。我们报道了一种新的分子设计，以加速负性光致变色联萘桥咪唑二聚体，BN ImD的热逆反应。我们还发现，用可见光照射的BN-ImD衍生物与桥接联萘单元上的甲基产生了前所未有的光反应产物，具有独特的八元环结构。这些观察结果为快速负光致变色分子的未来发展提供了有趣的线索。
The development of visible or near-infrared (NIR) light-responsive fast photoswitchable molecules for the real-time, non-contact control of physical and chemical properties has received increased attention because of the non-invasive features to materials and biological tissues. We report a new molecular design to accelerate the thermal back-reaction of the negative photochromic binaphthyl-bridged imidazole dimer, BN-ImD. We also found that irradiation of the BN-ImD derivative with methyl groups on the bridging binaphthyl unit with visible light produced an unprecedented photoreaction product with a unique eight-membered ring structure. These observations provide fascinating clues for the future development of fast negative photochromic molecules.
