Abstract

The introduction of innovative sensing approaches is of increasing interest in the development of analytical platforms and methodologies for the colorimetric, fluorimetric, and/or optical detection of important analytes. Herein, the synthesis of a novel squaraine derivative is reported, as well as its successful utilization in the colorimetric and fluorimetric determination of thiols. The reported squaraine was also evaluated as a pH sensor. In addition, a promising paper-based colorimetric method for mercury detection was developed and evaluated.
