In the present work, artificial light-harvesting systems with a fluorescence resonance energy transfer (FRET) process were successfully obtained in the aqueous solution. We designed and synthesized an amphiphilic pyrene derivative with two 4-vinylpyridium arms (Pmvb), which can interact with cucurbit[8]uril (CB[8]) to form supramolecular polymer through host-guest interactions in aqueous solution. The formation of supramolecular polymers results in a significant enhancement of fluorescence, which makes Pmvb-CB[8] an ideal energy donor to construct artificial light-harvesting systems in the aqueous solution. Subsequently, two different fluorescence dyes Rhodamine B (RhB) and Sulforhodamine 101 (SR101) were introduced as energy acceptors into the solution of Pmvb-CB[8] respectively, to fabricate two different artificial light-harvesting systems. The obtained artificial light-harvesting systems can achieve an efficient energy transfer process from Pmvb-CB[8] to RhB or SR101 with high energy transfer efficiency.

在目前的工作中，成功地在水溶液中获得了具有荧光共振能量转移 (FRET) 过程的人工光捕获系统。我们设计并合成了一种具有两个4-乙烯基吡啶臂（Pmvb）的两亲芘衍生物，它可以与葫芦[8]脲（CB[8]）在水溶液中通过主客体相互作用形成超分子聚合物。超分子聚合物的形成导致荧光显着增强，这使得Pmvb -CB[8] 成为在水溶液中构建人工捕光系统的理想能量供体。随后，将两种不同的荧光染料罗丹明 B (RhB) 和磺基罗丹明 101 (SR101) 作为能量受体引入Pmvb溶液中-CB[8] 分别制造两种不同的人工采光系统。所获得的人工光捕获系统可以实现从Pmvb -CB[8]到RhB或SR101的高效能量转移过程，具有很高的能量转移效率。
