摘　　要：Four new 1,8-naphthyridine derivatives were synthesized by reacting the parent molecules with aldehydes and characterized. Two of the compounds have completely new and unusual skeletons, and display red-fluorescence emissions and two-photon absorption. Their structures were determined using MS, 1D and 2D NMR, and density functional theory calculations. The structural investigations of 2-methyl-l,8-naphthyridine hydrochloride and hydrobromide showed that abundant hydrogen-bonds and π-π interactions lead to extended networks.Four new 1,8-naphthyridine derivatives were synthesized by reacting the parent molecules with aldehydes and characterized.
