Abstract
Embodiments of the present disclosure provide for methods for detecting the presence and/or concentration of anions in a solution, systems for detecting the presence and/or concentration of anions in a solution, anion sensor systems, and the like.
Claims15
A method of detecting anions, comprising:
- contacting a solution including an anion with a Pt(II) porphyrin;
- irradiating the solution with visible light;
- measuring a photoluminescence signal from the Pt(II) porphyrin;
- and
- determining the concentration of the anion;
- wherein the Pt(II) porphyrin is 5, 10, 15, 20-tetra(1-methyl-4-pyridino)-porphyrin Pt(II) tetrachloride, an analogue thereof, or a derivative thereof.
3 more elements
A sensor system, comprising:
- a structure having a Pt(II) porphyrin disposed on the surface;
- a compartment including a solution including an anion, wherein the anion and Pt(II) porphyrin interact to quench the photoluminescence of the Pt(II) porphyrin once the structure is placed in the compartment with the solution;
- a system for irradiating the solution with visible light;
- and
- a system for measuring a signal selected from a photoluminescence signal, UV-Vis signal, or a combination thereof, wherein a change in the signal relative to a signal without the anion present is correlated to the presence of the anion in the solution.
2 more elements
A method comprising, comprising:
- placing a structure having a Pt(II) porphyrin disposed on the surface in a compartment including a solution including an anion, wherein the anion and Pt(II) porphyrin interact to quench the photoluminescence of the Pt(II) porphyrin;
- irradiating the solution with visible light;
- and
- measuring a signal selected from a photoluminescence signal, UV-Vis signal, or a combination thereof, wherein a change in the signal relative to a signal without the anion present is correlated to the presence of the anion in the solution.
