Dodecanethiol chemical structure

FIGURE 8.1 Chemical structure of (a) polystyrene (PS), (b) poly(methyl methacrylate) (PMMA), (c) 8-hydroxyqui-noline (8HQ), (d) 1-dodecanethiol (DT), (e) 2-naphthalenethiol (2NT), (f) polyaniline (PANI), (g) tetrathiafiilvalene (TTF), and (h) methanofullerene [6,6]-phenyl C61-butyric acid methyl ester (PCBM). 

The crosslink structure was analyzed and quantified by thiol-amine analysis, which is based on treatment of the crosslinked material with a set of thiol-amine chemical probes, specifically cleaving particular crosslinks types [23], Polysulfide crosslinks are cleaved by treatment of crosslinked rubber samples with 2-propanethiol (0.4 M) and piperidine (0.4 M) in toluene for 2 h under inert gas atmosphere (argon) at room temperature, while polysulfide and disulfide crosslinks can be cleaved by treatment under the same conditions with 1-dodecanethiol (1 M) in piperidine for 72 h.
