Abstract: 2, 6-Distyryl-benzo[l,2d; 4,5d']bisoxazoles, 2,6-Distyryl-benzoCl ,2d; 5, 4d/]bisoxazoles, and some of their para substituted derivatives were treated with HMO method. The relevant energy levels and molecular diagrams were obtained. The substituent effect on UVabsorption spectra and FLemission spectra were analyzed and approached by some quantum chemistry methods on the basis of HMO theory.
