主　　题：Polyhedral oligomeric silsesquioxane(POSS) Network polymer Hypoxia Luminescent probe 

摘      要：There are numerous numbers of hypoxia-selective luminescent probes based on oxygen quenching of *** show a unique design for luminescent probes to detect hyperoxia utilizing hybrid networks consisting of aggregation-induced emission(AIE)-active dyes and disulfide *** the initial state,emission from the AIE-active dyes is inducible by suppressing energy-consumable intramolecular motions in the hybrid matrices,while the decrease in intensity was detected by releasing molecular motions corresponded to bond scission at the disulfide ***,it was shown that this process selectively proceeds in *** a result,positive luminescent signals were obtained in hyperoxia.
