摘要 <正> An effective method of synthesizing polyaromatic hydrocarbons with high selectivity was developed through our research work on the photocoupling reactions between several haloaromatic hydrocarbons and aromatic compounds. The structures of polyaromatic hydrocarbons synthesized were determined by IR, UV, ~1H NMR, MS and elemental analysis, and the crystal structure of 3-(1-naphthyl)-coumarin was established by an crystallographic analysis. Further study of the regioselectivity, orientational effect of substituents, solvent effect, sensitizing and quenching effect supported the proposed mechanism of this type of reaction involving election transfer process under excited triplet state.
