METHOD FOR THE DETECTION OF THIOLS IN AQUEOUS SOLUTION

摘要

The invention relates to a method for the detection of nucleophilic species with excess electronic charge, particularly thiol groups. The invention also relates to a series of squaraine-derived compounds. The inventive method is advantageous in that the thiols can be detected in aqueous solution from a simple, easily-noticeable change in colour. In this way, said method can be used to quantify the thiol concentration in the analysed solution.
