Combining carbon dots (CDs) with π-extended chromophores is an attractive way to study the electronic and energy processes of the former as a key step to many applications, including photosensing, photocatalysis, or photosensitization. CDs, in conjugation with chromophores, can have value in preparing donor–acceptor hybrids, and can also be used as scaffolds to support electronic communication between dyes. In this work, we conjugate two different rylene diimides, naphthalene and perylene diimides (NDI and PDI, respectively), with amorphous nitrogen-doped carbon dots. We take advantage of the imidization reaction between the amine-rich surface of the carbon dots and the monimide monoanhydride precursors of NDIs and PDIs, under microwave assisted conditions. The resulting (nano)hybrids were characterized also by spectroscopic methods. In particular, time-resolved spectroscopy for the multichromophoric array, consisting of CDs and both rylene diimides, allowed us to elucidate the complex inter-chromophoric interactions taking place in the excited state.

含富胺碳点和不对称亚芳基二酰亚胺的阵列的合成和激发态过程

将碳点（CD）与π扩展发色团结合在一起是研究前者的电子和能量过程的一种有吸引力的方法，这是许多应用（包括光敏，光催化或光敏化）的关键步骤。CD与发色团结合，在制备供体-受体杂体中可能具有价值，也可以用作支架来支持染料之间的电子通讯。在这项工作中，我们将两种不同的萘二甲酰亚胺，萘和per二酰亚胺（分别为NDI和PDI）与无定形氮掺杂碳点共轭。在微波辅助条件下，我们利用了碳点的富胺表面与NDI和PDI的一酰亚胺单酐前体之间的酰亚胺化反应。所得（纳米）杂化物也通过光谱法表征。尤其是，
