چکیده

Anchoring a BODIPY onto Ga(III)corrole via a meso-β linkage facilitated PeT in polar solvents, which quenched the fluorescence, and is further confirmed by electrochemical studies. The triad exhibits unprecedented crystal emission, which is not known for a corrole derivative, due to unique packing. Compound 4 hosts the first example of a novel B-F∙∙∙F interaction as well.

Photophysical Responses of Benzimidazolic and Benzoxazolic HydroxyCoumarin Dyes

We synthesized four novel benzoxazolic and benzimidazolic derivatives of 6-hydroxycoumarin and their photophysical properties were studied. The products with brilliant yellow color shades declared green fluorescence. The emission peaks of the products appeared 456–474 nm. The important characteristic for fluorescent compounds, the Stokes shift νA-νF, oscillator strength f, and fluorescence quan...

Near-IR phosphorescence of iridium(III) corroles at ambient temperature.

The photophysical properties of Ir(III) corroles differ from those of phosphorescent porphyrin complexes, cyclometalated and polyimine Ir(III) compounds, and other luminescent metallocorroles. Ir(III) corrole phosphorescence is observed at ambient temperature at wavelengths much longer (>800 nm) than those of most Ir(III) phosphors. The solvatochromic behavior of Ir(III)-corrole Soret and Q abs...

Synthesis and Crystal Structure of a Novel Six-Coordinate Gallium (III) Complex

The reaction of gallium (III) nitrate octahydrate with the proton transfer compound (pydaH2)2+ (pydc)2– ( where  pyda  is 2,6-pyridinediamine and pydcH2 is 2,6-pyridinedicarboxylic acid) leads to the formation of (C5H8N3) [Ga(C7H3NO4)2] · 4H2O · CH3OH. The crystal system of the anionic complex is triclinic with space group Pī and two molecules per unit cell. The unit cell parameters are a=10.23...

Tumor detection and elimination by a targeted gallium corrole.

Sulfonated gallium(III) corroles are intensely fluorescent macrocyclic compounds that spontaneously assemble with carrier proteins to undergo cell entry. We report in vivo imaging and therapeutic efficacy of a tumor-targeted corrole noncovalently assembled with a heregulin-modified protein directed at the human epidermal growth factor receptor (HER). Systemic delivery of this protein-corrole co...

Excitation Energy Delocalization and Transfer to Guests within MII4L6 Cage Frameworks

We have prepared a series of MII4L6 tetrahedral cages containing one or the other of two distinct BODIPY moieties, as well as mixed cages that contain both BODIPY chromophores. The photophysical properties of these cages and their fullerene-encapsulated adducts were studied in depth. Upon cage formation, the charge-transfer character exhibited by the bis(aminophenyl)-BODIPY subcomponents disapp...
