摘 要：Covalent organic frameworks(COFs),due to its high stability,large surface areas,good molecular tenability and excellent optical properties,has become a promising heterogenous photocatalyst for visible-light-driven organic transformations. Benefited from its inherent heterogenous nature,it can be readily removed from the organic reaction system,which is suited for the industrial application. In this context,a visible-light-driven protocol for the syntiesis of diverse 6-substituted-phenanthridines from 2-aryl phenyl isocyanides has been developed, in which the hydrazonc-based two-dimensional covalent organic frameworks(2 D-COF-1) was used as the heterogeneous *** protocol features excellent catalyst recyclability and high ***,it opens up doors to uncover more new photocatalytic organic approaches catalysed by covalent organic frameworks.
