模仿自然的“能量级联”结构,我们提出了一个基于圆柱形聚合物刷的单分子棒状纳米光采集器(NLH)。嵌段共聚物侧链携带(9,9-二乙基芴-2-基)甲基丙烯酸甲酯单元作为光吸收天线(能量供体),连接到含有9-蒽甲基丙烯酸甲酯单元作为发射基团(能量受体)的线性聚合物主链上。这些NLH表现出非常有效的能量吸收和转移。此外,我们通过调节给体-受体距离来控制能量转移。
Imitating the natural “energy cascade” architecture, we present a single‐molecular rod‐like nano‐light harvester (NLH) based on a cylindrical polymer brush. Block copolymer side chains carrying (9,9‐diethylfluoren‐2‐yl)methyl methacrylate units as light absorbing antennae (energy donors) are tethered to a linear polymer backbone containing 9‐anthracenemethyl methacrylate units as emitting groups (energy acceptors). These NLHs exhibit very efficient energy absorption and transfer. Moreover, we manipulate the energy transfer by tuning the donor–acceptor distance.
