The colorimetric and fluorometric detection of D-fructose was achieved by employing a two component sensing system composed of an arylboronic acid as the host molecule and a pH sensitive spirocyclic rhodamine dye as the indicator molecule.
Infrared dyes soluble in methylene chloride and having an infrared absorption maximum above 1100 nm are disclosed which have minor discolouration in the visual spectrum. The infrared dyes are especially useful for producing multicolour laser marked security documents having reduced background discoloration and enhanced colour gamut.
