“…[60][61][62][63] 52,66,74,75 Such systems constitute so-called ratiometric or self-referenced sensors, which are not affected by fluctuations of the excitation light intensity. While the well-established AIE has been exploited for the realization of oxygen sensors, 76,77 to the best of our knowledge, this is the first example of reporter where aggregation-enhanced dual emission with two different emitting excited states ( 3 MP-LC from monomers and 3 MMLCT from aggregates) is exploited in this field. An overview of the detailed Stern-Volmer analyses of the PS(PtLF-series) is given in the SI (Table S21).…”

“…Their applications include monitoring air quality, detecting hazardous gases, and clinical diagnosis. The target gases vary between volatile organic compounds 3 (VOCs), explosive gases, 4 highly-toxic gases, 5 and the other common gases, 6,7 depending on different scenarios. The analytical methods behind these sensors can be primarily divided into mass spectrometry, 8 electrochemical methods, 9 IR absorption, 10 and colorimetric/fluorescent methods.…”

“…An extremely fast response time and recovery time of oxygen sensing films were obtained in 4.0 s and 6.0 s, respectively. A very first example of a switchable AIE-active luminogen 59 ( Figure 14 ) has been recently reported that showed excellent sensitivity towards O 2 [ 94 ]. A complex-embedded EC polymer 59 exhibited fast quenching/recovering cycles ( Figure 15 C).…”
