保留了光化学特性-一种简单的卟啉-聚DMA结合物，能够在水中自组装成大的（约1 μm）囊泡。光动力学显着保存，尽管广泛的聚集。单个发色团的光化学性质的保留是生物捕光复合物的关键特征。尽管发色团的广泛聚集，这在合成的发色团组件中经常产生光谱特性的变化，但这是实现的。作为一种替代的方法，对模仿生物捕光复合物，我们报告的卟啉组件的合成保留的光化学性质的个别发色团单元，尽管他们的大量聚集。这些新材料强调了一种新的自下而上的方法，用于设计和理解更复杂的仿生和自然发生的生物系统。
Retained photochemical properties – a simple porphyrin–polyDMA conjugate with the ability to self assemble into large (∼1 μm) vesicles in water. The photodynamics are remarkably preserved despite the extensive aggregation. The retention of photochemical properties of individual chromophores is a key feature of biological light harvesting complexes. This is achieved despite extensive aggregation of the chromophores, which in synthetic chromophore assemblies often yields a change in spectral characteristics. As an alternative approach towards mimicking biological light harvesting complexes, we report the synthesis of porphyrin assemblies which retained the photochemical properties of the individual chromophore units despite their substantial aggregation. These new materials highlight a new bottom-up approach towards the design and understanding of more complex biomimetic and naturally occurring biological systems.
