Abstract

By AM1 method, the interactions between 1, 3-N, N’ -Bis-4-(4’ -nitro benzenediazo) phenyl squaraine (BNBPS) and several oxoacid anions have been studied on the basis of the proposed model. The mechanism of the color reactions is suggested and the answers to the question of whether or not BNBPS colorates with HCO -3 , CO 2-3 , NO2, NO3 etc. are given. It is theoritically predicted that BNBPS might be used as the color reagent for SO 24 .
