- Abstract
Bodipy building: meso ‐ Alkynyl BODIPY monomers and dimers were synthesized and their crystal structures, photochemical properties, and electronic structures disclosed. The meso ‐ arylethynyl group is coplanar with the BODIPY core. The resulting efficient π ‐ conjugation red ‐ shifts the intense absorption and bright fluorescence by about 40–70 nm. Cyclic voltammetry and DFT calculations revealed that the LUMO level is stabilized by meso ‐ alkynylation, while the HOMO level remains constant.
