The compounds (I) have good solubility in different organic solvents so that the compounds can be purified and formed into films conveniently; a plurality of diazo-aromatic condensed ring compounds can be obtained by introducing different substituent groups. The compounds (I) are expected to be widely applied in the fields of organic field effect tubes, organic light-emitting diodes, photovoltaic cells, organic nonlinear optics, fluorescence probes and laser dyes.

Description

technical field [0001] The invention relates to a class of azaaromatic condensed ring compounds based on carbazole and quinoline and a synthesis method thereof, in particular to the preparation of 14-hexyl-carbazolophenanthridine compounds by using a photocatalytic ring-closing reaction method, and belongs to the technical field of chemical industry. Background technique [0002] Aromatic fused ring compounds are formed by the fusion of multiple aromatic rings; these compounds have a large conjugated system, planarity and rigid structure. Aromatic fused ring compounds are widely used in fields such as organic field effect transistors, organic light-emitting diodes, photovoltaic cells, organic nonlinear optics, fluorescent probes, and laser dyes because of their special structures and physical and chemical properties. For example, CN103108875A provides a nitrogen-containing aromatic heterocyclic compound useful as an organic semiconductor material and an organic electronic de...
