Abstract

[anti-B18H22] is a potential blue laser material. In order to study the stability of [anti-B18H22] in aqueous solution, the hydrolytic reaction kinetic of [anti-B18H22] at various pH values and temperatures was studied by fluorescence spectroscopy. The results showed that [anti-B18H22] hydrolysis rate was accelerated by increasing temperature, and the trend showed that [anti-B18H22] hydrolyzed faster in low pH than in high pH solutions at the same temperature. The hydrolysis of [anti-B18H22] solution is second-order reaction at lower temperature (300.15–323.15 K), the activation energy is 52.37 kJ mol–1 and pre-exponential factor (A) is 7.9 × 1010. The work described here is significant for future studies of the properties of [anti-B18H22] in aqueous solution.
