摘要：Developing an easy-molding luminescent thermometer for low-temperature monitoring is significant in science and regular life. By combination of vibration-induced emission (VIE) and thermal expansion mechanisms, a ratiometric fluorescent polymeric thermometer is manufactured by dispersing bent N,N'-diphenyl-dihydrodibenzo[a,c]phenazine (DPAC) into moldable poly(dimethylsiloxane) (PDMS) for low-temperature detection from 177 to 277 K. Preliminary studies have shown that temperature-dependent emission can be visually detected and ratiometrically quantified. Moreover, this transparent-flexible thermometer can be not only coated on substrates but also molded into desired shapes. This work provides an innovative fabrication method for developing low-temperature ratiometric fluorescent polymeric sensors with visualization, transparency, flexibility, and moldability.
