Novel fullerene-functionalised poly(terthiophenes)

Polyterthiophene/CNT composite as a cathode material for lithium batteries employing an ionic liquid electrolyte

“…Rasch and Vielstich [6] have shown by cyclic voltammetry analysis that the charge storage capacity (doping level) of PTTh is higher than PBTh which in turn is higher than PTh. However, to our knowledge, PBTh and PTTh have not been evaluated for their cathodic performance in lithium battery devices except for one recent report on PTTh by Wallace and coworkers [7]. The terthiophene oligomer already possesses two ␣,␣ linkages of the thiophene unit and thus, polymerisation of this monomer is expected to produce PTTh with a more linear conjugated polymer structure that could have high charge storage capability.…”

Inherently Conducting Polymers via Electropolymerization for Energy Conversion and Storage

“…Unfortunately, no photoelectrochemical measurements were performed in order to probe PV properties in this study. Several investigations following a similar pattern of electrochemical characterization have also been reported concerning the electropolymerization of PTh precursors with pendant C 60 groups, namely, by the groups of Ferraris [62,63], Cravino [64][65][66][67], Komatsu [68,69], and Wallace [70,71]. Beyond the similar pattern of electrochemical measurements established in the first report by Sannicolo and coworkers, a limited number of more insightful investigations have been reported.…”

“…This approach avoids the problems associated with the simple blending of donors and acceptors, including phase separation and immiscibility of materials. Several examples of the electropolymerization of PTh precursors with covalently attached C 60 functionalities have been reported (Figure 11.3) [61][62][63][64][65][66][67][68][69][70][71]. The first such investigation was reported by Sannicolo and coworkers [61] for a cyclopentadithiophene-fullerene precursor ( Figure 11.3a), which was electropolymerized by CV.…”

“…Cravino et al [64] confirmed photoinduced electron transfer from the C 60 group to the PTh backbone of an electrodeposited polymer based on a bithiophene-fulleropyrrolidine (Figure 11.3c) using LESR spectroscopy. Yamazaki et al [69] [68], (e) an ethylenedioxy-substituted terthiophene-fullerene [69], and (f) N-methyl-2-(2-[2,2 ;5 ,2 -terthiophene-3 -yl]ethenyl) fullero [3,4]pyrrolidine [70,71].…”

Printing nanostructured carbon for energy storage and conversion applications

“…The properties of fullerenes can be controlled by attaching different functional groups to their surface [66][67][68]. Functionalized fullerenes are highly effective n-type organic semiconductors and they are therefore commonly used in solar cells as electron acceptors and conductors [69].…”
