Anodic oxidation of dipyrrolyls linked with flexible or rigid spacers: study of the electropolymerization mode

Precursor-controlled and template-free synthesis of nitrogen-doped carbon nanoparticles for supercapacitors

“…According to their findings, the oxidation of those molecules with two proximal pyrrolyl rings involved both intramolecular and intermolecular coupling process and tended to form polymers with different structures. 52 However, in the case of the hexapyrrolyl molecules reported by Lazerges et al 53 in which the benzene is substituted by several pyrrolyl residues, intramolecular coupling was also suggested but no dimer or polymer products were observed. Considering the structural analogy between OPN and hexapyrrolylbenzene (HPyB), we assume that the adjacent pyrrolyl residues of each OPN molecule also undergo an intramolecular coupling reaction.…”

“…Chane-Ching et al 52 investigated the oxidation process of a series of dipyrrolyl molecules with different flexible and bulky spacers. According to their findings, the oxidation of those molecules with two proximal pyrrolyl rings involved both intramolecular and intermolecular coupling process and tended to form polymers with different structures.…”

“…For the use of chain spacers in conductive polymers, see: Zotti et al (1997); Chane-Ching et al (1998); Just et al (1999). For related structures, see: Ramos Silva et al (2002Silva et al ( , 2005Silva et al ( , 2008.…”

Electrochemical synthesis of new conducting copolymers containing pseudo-polyether cages with pyrrole

“…For example, conducting polymers functionalized with crown ethers and polyether pseudo-cages have attracted great interest due to their complexing properties towards alkaline and alkaline-earth metal cations; therefore, such molecules and their polymers are good candidates for the extraction of metallic cations [1][2][3][4][5][6][7][8][9][10][11][12]. In recent years, there are some studies on N-substituted dipyrrolyl linked with flexible or rigid spacers (see Scheme 1) [13][14][15][16][17]. Leclerc and Simonet have synthesized monomers consisting of N-substituted pyrrolyl units linked by flexible polyether spacers [15,16].…”
