Five PAHs haptens 3 a~3 e were synthesized from naphthalene, anthracene, chrysene, pyrene and acenaphthene via two steps including Friedel-Crafts acylation and WolffKishner-Huang reduction. The sixth hapten 4-(acenaphthylen-3-yl)butanoic acid(3 f) was prepared from hapten 3 e via three steps including esterification, bromination and elimination. Their structures were confirmed by melting point, ~1H NMR and ^(13)C NMR. Their optical properties and crystal structures were also investigated. The results of density functional theory(DFT) calculation provided the supports that the size, shape(geometry) and electronic properties at the corresponding parts of 3 a~3 f did not change significantly, compared to those of PAHs. The haptens 3 a~3 f were coupled with bovine serum albumin(BSA) to make antigens. The coupling ratios were 1:20~1:38. These results show that the haptens could be used to induce specific antibodies for PAHs. 展开更多
