Photodynamic ion sensor systems with spiropyran: photoactivated acidity changes in plasticized poly(vinyl chloride).
نویسندگان
چکیده
We aim to introduce photoactivated optical ion sensors based on a triggered ion exchange process as novel dynamic tools. The quantification of the acidity change upon photoactivation of spiropyran within an organic membrane phase during photoexcitation is described here for the first time, suggesting a large pK(a) change of more than 6 orders of magnitude.

Reversible Photodynamic Chloride-Selective Sensor Based on Photochromic Spiropyran
We report here for the first time on a reversible photodynamic bulk optode sensor based on the photoswitching of a spiropyran derivative (Sp). The photoswitching of Sp induces a large basicity increase in the polymeric phase, which triggers the extraction of Cl(-) and H(+). Cl(-) is stabilized by a lipophilic chloride-selective ionophore inside the membrane, while H(+) binds with the open form ...

A new poly(vinylchloride) membrane sensor for Cr3+ ions based on di (benzylamino)glyoxime asan ionophore was prepared. The electrode has a linear dynamic range 1×10-6-1×10-1 mol l-1,with aNernstian slope of 20.3 ± 0.5 mV per decade and a detection limit of 2×10-7. It has a fast responsetime of
متن کاملThe Plasticizing Mechanism and Effect of Aluminium Chloride and Glycerin on Poly(vinyl alcohol) Films
Poly(Vinyl Alcohol) (PVA) films were prepared with AlCl3·6H2O/glycerin and AlCl3·6H2O/poly glycerin as two kinds of complex plasticizer. The micromorphology of pure PVA film and PVA films plasticized with complex plasticizer was observed by Scanning Electron Microscope (SEM). The interaction between complex plas...
متن کاملComparison of new optical sensor based on triazene ligand immobilized on PVC and triacetylcellulose membranes for Hg (II) Ion
For spectrophotometric analysis of Hg (II) ions, we have used and compared two membranes preparation methods using different polymer; one is poly(vinyl chloride) (PVC) and the other is triacetylcellulose (TAC). In the case of TAC membrane, it was treated with a ligand solution (1.166 × 10-3 mole L-1) in ethylenediamine at the ambient temperature for almost 2-5 min. However, in the case of PVC m...
متن کاملFlow-Injection Coulometric Detection Based on Ion Transfer and Its Application to the Determination of Chlorpromazine
A flow-injection coulometric method for the determination of chlorpromazine based on ion transfer into a plasticized poly(vinyl chloride) (PVC) membrane, was developed. The detector used consists of a flow-through cell that incorporates a plasticized poly(vinyl chloride) (PVC) membrane which contains tetrabutylammonium tetraphenylborate as electrolyte. The membrane is located between the flowin...
