December 2016Fluorescence Abstract:The fluorescence spectra and photostability under 532 nm laser excitation of four different common photoswitches (an azobenzene, spiropyran, indolylfulgide, and a diarylperfluorocyclopentene) was investigated in a silica microstructured optical fibre. An example of each photoswitch was examined both in solution as well as physically adsorbed to the silica fibre surface. This comparison was made to determine any fluorescence behavioral differences as a result of each solution and the optical fibre fluorescence sensing platform, and to determine which photoswitch has the best performance in this light intense microenvironment. It was found that the azobenzene and the spiropyran showed the most favorable behavior; showing a stronger fluorescence response and the least degradation of the fluorescence signal.

Surface Functionalization of Exposed Core Glass Optical Fiber for Metal Ion Sensing

“…The background fluorescence in both wet and dry state was similar, therefore, all the background signals reported in this paper are in dry state. The presence of the azobenzene moiety in the fluorophore molecule causes unavoidable background fluorescence [14,33]. All fibers pieces used for the sensing experiments were 15 cm long and were obtained by sectioning a 45 cm long fiber into three parts of equal length.…”

5′-Substituted Indoline Spiropyrans: Synthesis and Applications

“…This SP301 was designed on the basis of 5 -carboxy-SP coupled with a suitable ionophore fragment of the bis(2-pyridylmethyl)amine at C8-position that is capable of complexing with a metal ions. SP-based Zn +2 sensor SP301 is integrated into the surface of liposome [165,166].…”

Fundamentals and utilization of solid/ liquid phase boundary interactions on functional surfaces

“…However, there are drawbacks to overcome related to photoswitch-decorated surfaces, for example, the possible photodegradation [143] and the difficulties in achieving a surface coverage or complete control, sufficient for considerable wetting transitions. The preparation of photoswitch-decorated surfaces is usually an at least two-step process: at first, the elaboration of the base or substrate, then the subsequent binding of the photoswitches takes place [141].…”
