Synthesis of a Multichromophoric Array by Sequential CuAAC Reactions

Abstract : An easily synthesized α-hydroxy-β-azidotetrazole scaffold was used to build a three dimensional polychromic system. Different chromophores (coumarin, BODIPY and distyryl BODIPY) were incorporated into the structure by using sequential CuAAC reactions to form a series of dyads and a triad. A computational study of the resulting arrays showed that the predominant conformations brought the substituents into close spatial proximity. The triad exhibited FRET behaviour with notably efficient energy transfer values.
