Heteroleptic metallosupramolecular complexes of bodipy dyes as energy transfer cassettes.
نویسندگان
چکیده
Bodipy dyes with integral phenanthroline and terpyridine units heteroleptically assemble in the presence of zinc(II) ions to form energy transfer cassettes. These discrete complexes exhibit an approach to modularly designed efficient energy transfer and light harvesting systems through metal ion coordination.

Enhancing the Stokes' shift of BODIPY dyes via through-bond energy transfer and its application for Fe(3+)-detection in live cell imaging.
Two energy transfer cassettes that exhibit a large pseudo Stokes' shift (up to 400 nm) due to efficient through-bond energy transfer (up to 99%) have been constructed. Selective binding of Fe(III) with the donor entity significantly suppresses the excitation energy transfer resulting in fluorescence quenching in aqueous solution and in living cells.
متن کاملSpiranic BODIPYs: a ground-breaking design to improve the energy transfer in molecular cassettes.
Boosted excitation energy transfer in spiranic O-BODIPY/polyarene cassettes, when compared with the parent non-spiranic (flexible) system, is highlighted as a proof for the ability of a new structural design to improve the energy transfer in molecular cassettes.
متن کاملUnprecedented laser action from energy transfer in multichromophoric BODIPY cassettes.
A cassette molecule, featuring direct integration of two donor BODIPY units to one acceptor BODIPY unit, was conveniently developed as the first highly "through-bond energy transfer" (TBET) laser dye. This multicolor absorbing dye exhibited highly efficient and photostable laser action under drastic pumping conditions.

In search of viable strategies to identify selective inhibitors of protein kinases, we have designed a binding assay to probe the interactions of human phosphoinositide-dependent protein kinase-1 (PDK1) with potential ligands. Our protocol is based on fluorescence resonance energy transfer (FRET) between semiconductor quantum dots (QDs) and organic dyes. Specifically, we have expressed and puri...

As sensitizers take part in the absorption of solar radiation and injection of electrons into the conduction band of semiconductors, extensive research has been focused on the design of efficient and durable sensitizers. Several dyes have ...
