Heterogeneous photocatalysis is less common but can provide unique avenues for inducing novel chemical transformations and can also be utilized for energy transductions, i.e., the energy in the photons can be captured in chemical bonds. Here, we developed a novel heterogeneous photocatalytic system that employs a lead-halide perovskite nanocrystal (NC) to capture photons and direct photogenerated holes to a surface bound transition metal Cu-site, resulting in a N-N heterocyclization reaction. The reaction starts from surface coordinated diamine substrates and requires two subsequent photo-oxidation events per reaction cycle. We establish a photocatalytic pathway that incorporates sequential inner sphere electron transfer events, photons absorbed by the NC generate holes that are sequentially funneled to the Cu-surface site to perform the reaction. The photocatalyst is readily prepared via a controlled cation-exchange reaction and provides new opportunities in photodriven heterogeneous catalysis.

The invention discloses a method for preparing secondary aromatic amine or tertiary aromatic amine by conducting amination on aryl halide or alkyl halide. That is to say, the alkyl halide or the arylhalide and organic amine are mixed according to a certain ratio, and under light irradiation, C-N coupling reaction is carried out, so that a corresponding target product is generated for preparing the secondary amine or the tertiary amine. Compared with existing synthesis technologies, the method has the advantages that the aryl halide or the alkyl halide which is cheap and easy to get is selected as a reaction substrate, the method has good universality for different organic amine separately, moreover, the product selectivity is high, and separation and purification are easy; moreover, the synthesis method does not need to be conducted under severe conditions of high temperature and the like, a green and sustainable light source is adopted as driving force, the atom economy is high, andthe method has wide application prospects.
