M.p. 296 C. Accepts an electron from suitable donors forming a radical anion. Used for colorimetric determination of free radical precursors, replacement of Mn02 in aluminium solid electrolytic capacitors, construction of heat-sensitive resistors and ion-specific electrodes and for inducing radical polymerizations. The charge transfer complexes it forms with certain donors behave electrically like metals with anisotropic conductivity. Like tetracyanoethylene it belongs to a class of compounds called rr-acids. tetracyclines An important group of antibiotics isolated from Streptomyces spp., having structures based on a naphthacene skeleton. Tetracycline, the parent compound, has the structure ...

PT itself and substituted PTs are claimed to be useful as solid electrolytes in solid electrolytic capacitors PT [117, 118], 3-methylPT [119, 120], 3-ethylPT [120], 3-propylPT [120], 3-butylPT [121], 3-hexylPT [122], 3-octylPT [121], 3-dodecylPT [121], 3-docosylPT [121], and PEDT [59, 123]. A composite film of 3-dodecylPT and poly(ethylene terephthalate) is resistant to migration and can be used as a film capacitor [124].
