Abstract: On the basis of ZINDO, according to the sum over state expression, we designed the program for calculating the first hyperpolarizability β . The structures, electron spectra and β (-2ω,ω,ω), β (0,0,0) of a series of babituric acid derivative molecules have been studied.The influence of donor, π-conjugated bridge, acceptor, D-π-A, D-A, D-A-Dstructures on the β was examined.At last, we designed some molecules with excellent NLOproperties and good thermal stability, which have a prospect of practical applications

Key words: Nonlinear optical materials, Molecular design, First hyperpolarizability, Babituric acid derivatives
