Synthesis of new BODIPY derivatives including terpyridine and phenantroline, preparation of their metallosupramolecular complexes and energy transfer

In this study, terpyridine BODIPY and phenantroline BODIPY derivatives were synthesized for the preparation of their multicomponent metallosupramolecular Zn(II) self assemblies. For heteroleptic self agregation of the terpyridine BODIPY and phenantroline BODIPY derivatives along with the HETTAP approach, a sterically hindered phenantroline BODIPY derivative was made. In order for the metallosupramolecular complex architecture synthesis, phenantroline BODIPY derivate (26) was first complexed with Zn(OTf)2 at the same stoichiometry. Then, the metallosupramolecular complex structures were synthesized with the reaction of terpyridine BODIPY derivates ((15), (17), (31)) with this complex. After preparation of these aggregates, energy transfer properties were investigated by fluorescence and absorbance measurements. All synthesized metallosupramolecular aggregates showed efficient energy transfer from donor molecule to the acceptor molecule.
