[reaction: see text] We have designed and synthesized difunctionalized dendrimers containing two donors in the periphery and an acceptor at the core to serve as scaffolds for comparison with linear analogues to investigate the advantage of dendritic scaffolds for energy and charge transfer. Comparison of these dendrimers with the fully decorated dendrimers provides information on the advantage of chromophore density in energy/charge transfer from periphery to the core.
[反应:见正文] 我们设计并合成了在其外围含有两个供体且在核心含有一个受体的双功能树枝状大分子,用作支架以与线性类似物进行比较,从而研究树枝状支架在能量和电荷转移方面的优势。将这些树枝状大分子与完全修饰的树枝状大分子进行比较,可提供有关发色团密度在从外围到核心的能量/电荷转移中的优势的信息。
