| 摘 要： | 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_3~(2-), NO_2~(-), NO_3~-, etc. are given. It is theoretically predicted that BNBPS might be used as the color reagent for SO_4~(2-).

| 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 HCO3- , CO32- , NO2- , NO3- , etc. are given. It is theoretically predicted that BNBPS might be used as the color reagent for SO_4~(2-). |
