Photophysical behaviour of BODIPY-phenylacetylene macrocyclic dyads for light-harvesting applications†
Abstract
The synthesis and study of a family of BODIPY-phenylacetylene macrocycles where donor groups have been added to the macrocycle in order to tune the physicochemical properties and absorption profile is reported. Energy transfer is observed between this phenylacetylene antennae and BODIPY core and fluorescence emission from the BODIPY, at any excitation wavelength, is consistent with energy transfer from the macrocycle.
