Fig. 3. (a) Response intensity of the BODIQU-tBuCZ film to DCP vapor of different concentrations (0.001 ppt–1 ppm). (b) The comparison of DCP sensing performance of representative methods reported in the literature. (c) Response intensity of the sensor to the presence of DCP and other vapors. (d) Two-dimensional PCA score plot based on fluorescence response intensity, recovery time, and response time for discrimination of chemical analytes (n = 6 replicates per analyte). (e) Results from continuous recyclability tests using the film-based sensor in the presence of the vapors of 10 ppb DCP (50 cycles).
