Artificial light‐harvesting systems have attracted great interest in biological photosynthesis and photo‐voltaic devices areas due to their unique structures, easy purification, low‐cost, and convenient processing abilities. Here, two dendritic molecules based on triphenylamine and naphthalimide have been designed and synthesized, their structures were confirmed by ¹H NMR, ESI‐MS, and high resolution mass spectrometry. In these molecules, triphenylamine units perform as the electron donor moiety, and naphthalimide units perform as the electron acceptor. The obvious quenched fluorescence intensity and considerably shortened lifetime of the dendritic molecules combined with the molecular frontier orbital energy levels proved that the dendritic molecules not only are good candidates as hole‐transporting materials but also are two excellent photo‐induced electron transfer materials. Therefore, it is believed that these dendritic molecules have potential application value in photo‐voltaic devices.

两种基于萘二甲酰亚胺和三苯胺的树枝状分子的合成和荧光性质

人工采光系统由于其独特的结构，易于纯化，低成本和便捷的处理能力，在生物光合作用和光伏设备领域引起了极大的兴趣。在此，设计并合成了基于三苯胺和萘二甲酰亚胺的两个树枝状分子，其结构由¹确证。H NMR，ESI-MS和高分辨率质谱。在这些分子中，三苯胺单元用作电子给体部分，萘二甲酰亚胺单元用作电子受体。树枝状分子明显的猝灭荧光强度和明显缩短的寿命，再加上分子前沿的轨道能级，证明树枝状分子不仅是空穴传输材料的良好候选者，而且还是两种优异的光诱导电子转移材料。因此，人们认为这些树枝状分子在光伏器件中具有潜在的应用价值。
