Abstract
Chlorogenic acid (CGA) is widely used for biological and pharmacological activities. CGA can be harmful in high concentrations, so its control in wastewater became essential. Indicators or optical sensors are a practical and convenient way to detect CGA. In this context, porphyrins are widely used as optical receptors since they have a strong visible absorbance and may be fluorophores. Here, the UV-vis and fluorescence spectra revealed that meso-tetra (N-methyl-4-pyridyl) porphyrin (TMPyP) interacts with CGA at low molar ratios, suggesting its potential use for an optical sensor.
