The Huisgen’s cycloaddition of BODIPY acetylene and ferrocene azides in supercritical CO2

The copper-catalyzed azide–alkyne cycloaddition of BODIPY acetylene derivative and ferrocene azides in supercritical CO2 at 80 °C and 81 bar affords the corresponding triazole-containing BODIPY–ferrocene conjugates in high yields. The fluorescent and electrochemical properties of the compounds thus obtained were explored.
