Ultrafast dynamics of a new class of highly fluorescent boron difluoride dyes.
The first ultrafast study of the dimeric fluorescent BF2 dye BOPHY is presented. When compared to a structurally related BODIPY dye, similar photophysical dynamics are observed, including an intermediate kinetic component present in both dye types.
متن کاملBoron difluoride complexes of 2′-hydroxychalcones and curcuminoids as fluorescent dyes for photonic applications
The field of fluorescent boron complexes has witnessed tremendous developments in recent years. In that context, we have investigated two series of boron difluoride complexes based on 2′-hydroxychalcone and curcuminoid ligands that represent naturally occurring pigment structures. The dyes display significantly large Stokes shift values, indicating that an ICT state is involved as lower-energy ...
متن کاملStructural diversity of new solid-state luminophores based on quinoxaline-β-ketoiminate boron difluoride complexes with remarkable fluorescence switching properties.
A series of structurally simple yet highly tunable organoboron luminophores was designed and synthesized. The solid-state fluorescence quantum yields exhibit nearly exponential growth by decorating the luminophore with additional sterically demanding substituents. Uniquely, the luminescence of these organoboron dyes can be easily switched on/off by acidic/basic vapors, yielding a solid-state fl...
متن کاملSynthesis, structures and electrochemical and photophysical properties of anilido-benzoxazole boron difluoride (ABB) complexes.
A new series of four-ring-fused π-conjugated anilido-benzoxazole boron difluoride (ABB) dyes were synthesized by employing an unsymmetrical bidentate ligand under a mild reaction condition. X-ray structural analysis demonstrated that the four-ring-fused π-conjugated skeleton is nearly coplanar, and almost orthogonal to the side anilido phenyl group with dihedral angles of 74-86°. The synthesize...
متن کاملEvaluation of Anisole-Substituted Boron Difluoride Formazanate Complexes for Fluorescence Cell Imaging.
Evaluation of three subclasses of boron difluoride formazanate complexes bearing o-, m-, and p-anisole N-aryl substituents (Ar) as readily accessible alternatives to boron dipyrromethene (BODIPY) dyes for cell imaging applications is described. While the wavelengths of maximum absorption (λmax ) and emission (λem ) observed for each subclass of complexes, which differed by their carbon-bound su...
