Azamacrocyclic fluorophores
containing piperazine units were synthesized using
sequential rhodium-catalyzed regioselective hydroformylation-reductive amination.
A piperazine unit is introduced into the macrocycles to act simultaneously as electron donor and
binding site. The macrocycles chelate
divalent cations, either Zn2+ or Co2+,
which considerably enhanced fluorescence. Complexation
with Zn2+ was additionally confirmed by NMR.
