pyridyl/isoquinolyl-imine-isoindoline (L1 and L2), have been selected as ancillary ligands to form two novel neutral cyclometalated heterolepticiridiumcomplexes (Ir(III)(dfppy)2(LN^N)), in which dfppy is the cyclometalated ligand 2-(2′,4′-difluorophenyl)pyridine. Both complexes exhibit broad emission spectra at red-visible region. By fusion with benzene ring of the ancillary ligand, further bathochromic
The synthesis of boron-pyridyl-imino-isoindoline dyes, a novel type of BODIPY analogue, involves a facile and scalable two-step reaction. Broad envelopes of intense vibrational bands are observed for the main spectral bands in the absorption and emission spectra. High fluorescence quantum yields are obtained in solution, with significant intensity also observed in the solid-state.
A small series of keto-isoindolinyl and pyridyl-containing boron complexes with significant large Stokes shifts and solvatochromic fluorescence are reported.
