天然光合系统利用大量的光收集发色团来收集阳光，这些发色团将吸收的能量引导到一个单一的反应中心。最近，人们已经意识到树突大分子可以表现出类似的性质，尽管规模更小。树突结构和组件的制备是由许多收集光的发色团组成的，这些发色团将它们的能量转移到核心的单个能量“汇”中，这是通过许多不同的和创造性的方式实现的。这些新颖的结构被用作发光二极管、信号放大器、荧光传感器、变频器和其他光子器件的模型系统。
Natural photosynthetic systems collect sunlight using a vast array of light-harvesting chromophores that channel the absorbed energy to a single reaction center. Recently, it has been realized that dendritic macromolecules can exhibit similar properties, though on a more modest scale. The preparation of dendritic structures and assemblies composed of numerous light-collecting chromophores that transfer their energy to a single energy 'sink' at the core has been achieved in a number of diverse and creative ways. These novel structures are being used as model systems in light-emitting diodes, signal amplifiers, fluorescent sensors, frequency converters, and other photonic devices.
