Owing to the intriguing light driven molecular switch, photochromic compounds have been extensively investigated as key materials in switching and sensor devices. For effective functioning of a fluorescence-coupled spiropyran photoswitch, it must incorporate a FRET system in which emission from the fluorophore is absorbed efficiently by the MC form of the photochromic molecule. In this regard, P3HT are very attractive substances. We observed MC form of the spiropyran is able to absorb the emission from P3HT efficiently. As a consequence, the spiropyran-P3HT system is ideally suited for incorporation into a FRET based photoreversible switching system. Encouraged by the photophysical properties related to the donor emission and acceptor absorption of spiropyran and PT, we designed a photoswitchable spiropyran-polythiophene conjugate P(TSP/3HT). The spiropyran-polythiophene conjugate system can also be used to detect cyanide anion in a highly selective and sensitive manner. |
