The design and construction of an artificial light-harvesting system in water by mimicking the energy transfer cascade in natural photosynthesis are of significant importance. Herein, we report an efficient two-step sequential energy transfer system based on quadruple hydrogen-bonded supramolecular polymeric nanoparticles. By loading two types of hydrophobic dyes as energy acceptors, excitation energy from the supramolecular polymer could be funneled efficiently to the final acceptor through the relay acceptor. The system exhibits tunable multicolor emission from blue through yellow to red, as well as white light emission.
通过模拟自然光合作用中的能量传递级联来设计和构建水中的人工光捕获系统具有重要意义。在此，我们报告了一种基于四重氢键超分子聚合物纳米粒子的高效两步顺序能量转移系统。通过负载两种类型的疏水性染料作为能量受体，超分子聚合物的激发能量可以通过接力受体有效地传递到最终受体。该系统表现出从蓝色到黄色再到红色的可调多色发射以及白光发射。
