设计并构建了一种基于超分子有机凝胶的人工捕光系统（ALHS），该超分子有机凝胶由简单的酰肼官能化苯并咪唑衍生物（HB）和荧光染料罗丹明B（RhB）组成。RhB作为一个很好的受体，以实现能量转移过程具有良好的效率的基础上HB/RhB组件，这表明相当大的荧光共振能量转移（FRET）效率为53%的能量转移过程。值得注意的是，所获得的系统显示出上级的颜色转换能力，将蓝光转换成橙子光。通过适当调节供体与受体的比例，获得了明亮的橙子光发射，具有35.5%的高荧光量子产率。该系统显示出与可见光光转换有关的应用前景。
An artificial light-harvesting system (ALHS) has been designed and constructed based on supramolecular organogels made of a simple hydrazide-functionalized benzimidazole derivative (HB), as well as the fluorescent dye rhodamine B (RhB). RhB acted as a good acceptor to realize the energy-transfer process with good efficiency based on a HB/RhB assembly, which showed considerable fluorescence resonance energy transfer (FRET) efficiency of 53% for the energy transfer process. Remarkably, the obtained system showed superior color conversion abilities, converting blue light into orange light. By properly tuning the donor to acceptor ratio, bright orange light emission was achieved with a high fluorescence quantum yield of 35.5%. This system exhibited promise for applications relating to visible-light photo-transformation.
