“…Previous electrochemical studies of PTCDA in DMF, 30 and recent studies of poly(ethylene oxide)-modified bisimides of PTCDA (PTCDI-PEO), which increases the solution solubility of these materials, 31 show that the first reduction potential of the perylenetetracarboxylicdianhydride core is -0.5 to -0.6 V vs SCE, in either acetonitrile or DMF solutions, i.e., 0.35-0.41 V more positive of the first reduction potential of ZnPc and ca. 0.20 V more positive of the first reduction potential of ClInPc.…”

The offsets between the highest occupied molecular orbitals (HOMO) and the lowest unoccupied molecular orbitals (LUMO) at the 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA)/chloroindium phthalocyanine (ClInPc) and PTCDA/zinc phthalocyanine (ZnPc) organic heterojunctions were estimated from a combination of X-ray and ultraviolet photoemission (XPS,UPS) measurements. This combined method allows an improved determination of the electronic structure of such organic/organic‘ interfaces due to the separate determination of the band bending (charge redistribution) following heterojunction formation. Both interfaces have large offsets in the onset for photoemission from their HOMO levels (PTCDA/ZnPc: 0.88 eV; PTCDA/CnlInPc: 0.93 eV). Using thin film absorbance data, the corresponding offsets in LUMO levels were estimated to be 0.66 eV (PTCDA/ZnPc) and 0.34 (PTCDA/ClInPc). The ZnPc/PTCDA interface showed a significant interface dipole (0.25 eV) while the ClInPc/PTCDA contact was essentially dipole free.

“…Even though studies mentioned in the remainder of this section do not involve designing new remediation procedures, the articles below describe the electrochemistry of some interesting compounds. de Luca and colleagues used cyclic voltammetry with a glassy carbon cathode in dimethylformamide to examine the electrochemical behaviors of tetrabromo- and tetrachlorophthalic anhydride. Troll and Ollmann reduced brominated and chlorinated derivatives of phthalic anhydrides, along with phthalic imides, to electrosynthesize some 1,3-bis(trimethyl)silyloxy-substituted isobenzofurans and isoindoles.…”

Electrochemical reduction of halogenated organic compounds is gaining increasing attention as a strategy for the remediation of environmental pollutants. We begin this review by discussing key components (cells, electrodes, solvents, and electrolytes) in the design of a procedure for degrading a targeted pollutant, and we describe and contrast some experimental techniques used to explore and characterize the electrochemical behavior of that pollutant. Then, we describe how to probe various mechanistic features of the pertinent electrochemistry (including stepwise versus concerted carbon-halogen bond cleavage, identification of reaction intermediates, and elucidation of mechanisms). Knowing this information is vital to the successful development of a remediation procedure. Next, we outline techniques, instrumentation, and cell designs involved in scaling up a benchtop experiment to an industrial-scale system. Finally, the last and major part of this review is directed toward surveying electrochemical studies of various categories of halogenated pollutants (chlorofluorocarbons; disinfection byproducts; pesticides, fungicides, and bactericides; and flame retardants) and looking forward to future developments.

“…Although the main purposes of studies reported in the remaining paragraphs of this section do not entail the development of a remediation technique, these papers are germane to the electrochemical behavior of some interesting compounds. Luca et al [153] investigated the cyclic voltammetric behavior of tetrabromo-and tetrachlorophthalic anhydride at a glassy carbon electrode in DMF-TEAP. Electrochemical reduction of brominated and chlorinated derivatives of phthalic anhydrides and phthalic imides was employed by Troll and co-workers [154] for the synthesis of 1,3-bis(trimethyl)silyloxy-substituted isobenzofurans and isoindoles.…”

<p>This review summarizes our own research, published since 2004, dealing with electrochemical reduction of halogenated organic compounds that are environmental pollutants. Included are sections surveying the direct and mediated reduction of the following species: (a) chlorofluorocarbons; (b) pesticides, fungicides, and bactericides; (c) flame retardants; and (d) disinfection by-products arising from the chlorination of water. To provide the reader with a perspective of these topics beyond our own work, a total of 238 literature citations, pertaining to studies conducted in numerous laboratories around the world, appears at the end of this review.</p>
