a Molecular structure of TBSMP, and TBSMSPy+. b UV-vis spectra of TBSMP and TBSMSPy+. c Normalized PL spectra of films of compounds. d The plots of the αAIE versus the composition of the toluene mixture of TBSMP and TBSMSPy+ αAIE = I/I0, I0 = PL intensity in pure DMSO. e, f Plots of relative PL intensity of DCFH (for general ROS detection) in the presence of TBSMP and TBSMSPy+ upon exposure to 450 nm laser (10 mW•cm−2) in air-saturated (e) and deoxygenated (f) solution. I0 and I are the PL intensities of the indicator before and after irradiation, respectively. g Electron spin resonance (ESR) curves of TBSMP and TBSMSPy+ in DMF before and after exposure to 450 nm laser (10 mW•cm−2) in deoxygenated solution.
