Self-enhanced multicolor electrochemiluminescence by competitive electron-transfer processes

Abstract

Controlling electrochemiluminescence (ECL) color(s) is crucial for many applications ranging from multiplexed bioassays to ECL microscopy.

Utilizing Selective Chlorination to Synthesize New Triangulenium Dyes with Redshifted Absorption and Emission

“…[8][9][26][27] Finally, the chlorinated systems are obvious starting points for coupling reactions aiming for -system extension. [28][29][30] Experimental section: Synthetic Methods and Materials. All chemicals and solvents were purchased from commercial suppliers and used as received, except for 3 which was synthesized as described in the litterature 20 .…”

Near-infrared electrochemiluminescence in water through regioselective sulfonation of diaza [4] and [6]helicene dyes

“…16,17 Recently, we reported self-enhanced multicolor ECL using a water-soluble diaza [4]helicene bearing a tertiary dimethylamino-terminated group. 20 Aside those helicene luminophores, very efficient organic ECL dyes have been designed and reported in organic media. [13][14][15]21 However, a major challenge is to obtain such bright organic ECL emitters operating in physiological conditions (i.e.…”

Emission from the working and counter electrodes under co-reactant electrochemiluminescence conditions

“…[3][4][5] This has been increasingly exploited to simultaneously or selectively excite multiple luminophores in multi-colour and/or potentialresolved ECL systems. [6][7][8][9][10][11][12] In traditional ECL experiments, the emission is generally assumed to emanate near the surface of the working electrode, with occasional observations of ECL at the counter electrode dismissed as an unwanted interference. 5, 13 Moreover, conventional ECL detectors such as a photomultiplier tube (PMT) or charge coupled device (CCD) spectrometer measure the cumulative ECL from the electrochemical cell.…”
