Influence of spacer in the formation of nanorings by templateless electropolymerization

A soft template approach to various porous nanostructures from conjugated carbazole-based monomers

“…In water (H2O), porous structures were reported especially with pyrrole as monomer but a surfactant is needed to stabilize the gas bubbles (O2 and/or H2 depending on the electropolymerization method) released by the water oxidation and/or reduction. This method has also been reported in organic solvent like dichloromethane (CH2Cl2) and without surfactant with different conductive polymers such as poly (3,4phenylenedioxythiophene), poly (3,4-naphthalenedioxythiophene), and recently thienothiophenes [23][24][25][26][27][28][29], giving surfaces with strong water adhesion.…”

Templateless Electrodeposition of Conducting Polymer Nanotubes on Mesh Substrates

“…Here, H 2 O was added to anhydrous CH 2 Cl 2 in order to release a high amount of O 2 and H 2 bubbles, depending on the polymerization method as reported in the literature. [ 34 ] Then, the electrodepositions were performed by cyclic voltammetry from −1 V to the monomer oxidation potential ( E ox = 1.75 V vs SCE for Thieno‐Py, E ox = 1.73 V vs SCE for Thieno‐ C 4 F 9 , E ox = 1.68 V vs SCE for Thieno‐ C 8 F 17 , E ox = 1.77 V vs SCE for Thieno‐ OH) and at a scan rate of 20 mV s −1 . Different number of scans were performed (1, 3, and 5) in order to better investigate the polymer growth.…”

Tunable Nanoporous Structures with Rose Petal Effect by Soft‐Template Electropolymerization of Benzotrithiophene Monomers

“…Previous researches on thienothiophene-based monomers showed very interesting results. [25,29] Here, also to planarity of the thienothiophene moiety favored the unidirectional growth by π-π stacking but…”

“…The soft-template electropolymerization was reported as a very nice strategy to prepare on substrates ordered porous structures such as nanotubes. [20][21][22][23][24][25][26][27][28][29][30][31] The electropolymerization of pyrrole directly in water (H 2 O) was very studied in the literature. [20][21][22][23][24] Depending on the deposition method it is possible to form on the substrate gas bubbles (O 2 and/or H 2 ) acting as soft-template for the growth of nanotubes.…”

“…Because most of the monomers are not soluble in water, this process was pursued in organic solvent. [25][26][27][28][29][30][31] In organic solvent, H 2 O can be added in solution for releasing on the substrate gas bubbles acting also as soft-template for the preparation of porous structures and H 2 O content as a huge influence, especially on the numbers of nanotubes. The influence of H 2 O content was determined by comparing the results obtained in dichloromethane (CH 2 Cl 2 ) and in dichloromethane saturated with water, called (CH 2 Cl 2 + H 2 O).…”
