meso-Tetraarylporpholactones as high pH sensors
The Analyst, 2010The ability of meso-tetra(pentafluorophenyl)porpholactone (T(F)PL) and its Pt(II) complex [meso-tetra(pentafluorophenyl)porpholactonato]Pt(II) (T(F)PLPt) to function as optical high pH sensors is described. Under strongly alkaline or high methoxide conditions, their UV-vis spectra undergo dramatic and reversible red-shifts.

Model For An Optical Fiber Ph Sensor
SPIE Proceedings, 1987The present paper is concerned with the design of a model of fiber optic sensor for pH measurement in the physiological range (7. 0-7. 5). Up to now a few pH fiber optic sensor have been developed. The model here described makes use of a liquid optrode, formed by a dye solution contained within a membrane, attached to the end of a couple of optical ...

Dynamic photonic structures can be modulated by changing the periodic structure and/or the index of refraction. These dynamic photonic structures allow responsive capability for sensing external stimuli to control the properties of light and act as optical transducers.
