Novel cassettes capable of energy transfer involving simple synthetic methods viz., copper catalyzed azide–alkyne cycloaddition (click reaction) at the C-8 position and palladium catalyzed Suzuki–Miyaura cross coupling at the C-6 position have been represented. The resulting imidazo[1,2-a]pyrazine-triazole bridged coumarin cassettes are capable of energy transfer from a donor core to an acceptor moiety.
