“…MEH-PPV has been intensely studied over the last decade for application in organic LED [14][15][16] and photovoltaic devices [17][18][19]. The electrochemical properties of MEH-PPV have been similarly well documented [13,20,21]. CV performed on MEHPPV showed that the oxidation potential for the p-doping scan occurred at 0.62 V. The oxidation potentials of the polymers presented here are greater than that of MEH-PPV.…”

“…Table 1 summarises the oxidation and reduction potentials of MEH-PPV and the polymer series. The n-doping or reduction scans of POPV, POPV-ONV and PONV-OAV were all shown to be quasi reversible, where as the PONV and POPV-OAV scans were fully reversible [13]. POPV and the POPV-ONV polymers did not produce uniform thin films on the electrode.…”

“…The POPV-ONV and the POPV-OAV show strong oxidation peaks but as there is very little quasi reduction in the POPV-ONV and POPV-OAV, hence these have an irreversible electrochemical responses under p-doping conditions. In each case if the potential were increased past the oxidation peak of each polymer, the electroactivity of the polymers was lost permanently due to over oxidation [13]. The polymers can be compared to poly (2-methoxy-5-(20-ethylhexyloxy)-1,4 phenylenevinylene) (MEHPPV).…”

The electrochemical properties of a newly synthesised set of PPV derivatives were measured by cyclic voltammetry. A new octyloxy substituted PPV derivative was first synthesised (POPV). The structure of the POPV is varied systematically by the replacement of the phenyl units by naphthyl and anthryl units and the effect of these variations on the electrochemical properties is explored. The HOMO-LOMO levels of the polymers were determined from the onset potentials for the p-doping and n-doping scans. From this the electrochemical bandgap for each of the polymers was calculated. The systematic change in the structure of the POPV results in a systematic increase in the LOMO level of the polymer series whereas a concomitant increase in HOMO level results in an overall increase in the bandgap of the polymers series. The variation in the electrochemical, optical properties and vibrational properties observed within the polymer series were all found to correlate with the structural changes made, pointing towards structure property relationships and a guide to future synthetic strategies.

“…Due to the high fluorescence quantum yields and stable radical cations and anions in aprotic media, ECL generation by aromatic hydrocarbons such as rubrene and 9,10-diphenylanthracene (DPA) has been studied in detail by Hercules and Bard et al in the mid-1960s [8][9][10][11]. In addition, other organic emitters including acridinium esters [12], polymers [13][14][15], siloles [16], and boron-dipyrromethene (BODIPY) dyes [17][18][19][20][21] have also been extensively investigated. (ii) Inorganic systems: in 1960s and 1970s, ECL as a novel photochemical and electrochemical phenomenon has aroused much interest of investigation, and a variety of compounds, complexes, and clusters have been studied.…”

Electrochemiluminescence (ECL), also called electrogenerated chemiluminescence, is luminescence that is produced by chemical reactions triggered by electrochemical method. ECL imaging is a novel imaging technique, which can simultaneously provide two kinds of signals of both electrochemistry and optical image. Over the past two decades, ECL imaging has been not only a powerful tool for investigating the fundamental scientific questions such as ECL mechanisms and reaction kinetics, but also a versatile analytical technique for detection of a wide range of analytes including small molecules, DNA, proteins, and cells. In the first part of this review, we briefly describe the reaction mechanisms of ECL generation. Then the review focuses on the research progress on the ECL imaging approach. It is basically introduced from the following five aspects: (i) visualization of electroactive sites on surfaces, (ii) imaging analysis at the single-bead and single-cell levels, (iii) array bioanalysis, (iv) multi-color ECL imaging, and (v) paper chip based on ECL imaging. Finally, some perspectives and future directions in this active research area are presented.

“…This can be done by different methods that allow deposition of organic films. The examples of ECL from the films on the electrode containing electrochemiluminescer molecules are known [5][6][7][8]. In our previous works [9,10] we proposed deposition of Langmuir-Blodgett (LB) films with incorporated electrochemiluminescers on the working electrode of ECL sensor to allow use of water-insoluble electrochemiluminescers which considerably extend range of substances that can be used for ECL generation.…”

Processes of nonradiative excitation energy transfer and excited states quenching in electrochemiluminescent sensor with working electrode, modified by Langmuir-Blodgett film with incorporated electrochemiluminescer molecules, are investigated by means of mathematical modeling. Comparison with experimental results revealed that considered model is applicable for Langmuir-Blodgett films thinner than 10 monolayers. The optimal thickness of the film for electrochemiluminescent sensor operation was estimated as 3-5 monolayers.
