Electrogenerated chemiluminescen 71.photophysical, electrochemical, and electrogenerated chemiluminescent properties of selected dipyrromethene-BF (sub 2)dyes

Article Abstract:

The photochemistry, electrogenerated chemiluminescence (ECL) properties of five boron-containing dipyrromethene-BF (sub 2) PM-BF (sub 2) dyes was investigated. Dyes with a lower degree of substitution showed higher fluorescence efficiencies, as exemplified by BODIPY and PM 546 (8-Me), however the lack of electron-donating substituents in positions 2,6and 8 caused a decrease in the stability of the cation and anion radicals, leading to irreversible electrochemical oxidation and reduction.

Scanning electrochemical microscopy and conductive probe atomic force microscopy studies of hydrogen-terminated boron-doped diamond electrodes with different doping levels

Article Abstract:

The pattern of conductivity and electrochemical activity at the surfaces of hydrogen-terminated boron-doped diamond electrodes is calculated using conductive probe atomic force microscopy (CP-AFM) and scanning electrochemical microscopy (SECM). CP-AFM indicates that the surface is predominantly insulating, with discrete conducting areas of less than two macrometer in diameter and nonuniformly distributed on the surface.

Demonstration of electrochemical generation of solution-phase hot electrons at oxide-covered tantalum electrodes by direct electrogenerated chemiluminescence

Article Abstract:

A study was conducted to investigate the electrochemical generation of solution-phase hot electrons at oxide-covered tantalum electrodes using direct electrogenerated chemiluminescence. Polarographic grade tetra-n-butylammonium perchlorate was utilized as the supporting electrolyte. The Princeton Applied Research model 173/175 potensiostat/universal programmer was then used to carry out electrolysis experiments.
