Efficient electrochemiluminescence of a readily accessible boron difluoride formazanate dye.

چکیده
Electrochemiluminescence (ECL) of a boron difluoride formazanate dye was investigated in the presence of tri-n-propylamine as a reductive co-reactant. The ECL mechanism was studied using ECL-voltage curves, spooling ECL, and accumulative ECL spectroscopy. The ECL occurs at 724 nm by three distinct, voltage-dependent mechanisms of light emission.

Evaluation 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...

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 ...

Two series of novel boron difluoride adducts (BDFs), namely [BF(2)(OO(R(n)))] (type I) and [BF(2)(OO(2R(n)))] (type II) (R = C(6)H(4)OC(n)H(2n+1); n = 10-18), containing β-diketonate ligands bearing 4-alkoxyphenyl substituents in position 1 or in positions 1,3 of the β-diketonate core, respectively, have been prepared. All of them display a strong interaction between the ligand and the BF(2) gr...
