  • The detection of explosives is crucial for civilian safety and environmental protection. The detection in harsh conditions, such as different pH values, is rarely reported. In this paper, using an AIE-active hyperbranched polymer (hb-P1a), the pH effect on explosive detection in aqueous was first studied. The hb-P1a aggregates are highly sensitive to explosive in acid to basic media, indicating that they are tolerant to various pH conditions. Improved detection e±ciency of the polymer was recorded in the acid solution (K up to 8.26 *10^4 M-1. Furthermore, the prototype devices of hb-P1a infilter papers could sense the PA in varying pH solutions. These advantages make the polymer a good candidate for explosive detection in various practical applications.
