H-Chromophores have technically useful oxidation-reduction properties, which have been exploited for thousands of years in textile dyeing by the “vatting” process. Thus indigoid-type dyes can be reduced in a two-stage process to the so-called “leuco dianions”, which unlike the original dyes are readily soluble in water and have a high affinity for cellulosic fibres. In recent years this redox behaviour has also found use in the area of functional dyes, particularly where the colour change associated with reduction/oxidation can be employed in sensors and indicators, e.g. in enzyme assay and diagnostic systems. |
