Effects of magnetic processing on electrochemical and photoelectrochemical properties of electrodes modified with nanoclusters of a phenothiazine-C₆₀linked compound

Orientation of Nanowires Consisting of Poly(3-butylthiophene) Using Strong Magnetic Field

“…The magnetic processing of the samples was performed using a superconducting magnet with a vertical (B max ¼ 10 T) magnetic field. 24,35) A superconducting magnet [Oxford Instruments, low-loss 10 T high-field solenoid system S10-76.5 (60 RT)/-B] with a vertical magnetic field was used. 5) The magnet had a bore tube of 60 mm without an aluminum thermostat present and a bore width of 40 mm with the thermostat.…”

“…We have recently reported the effects of magnetic processing on the morphological, electrochemical, and photoelectrochemical properties of electrodes modified with nanoclusters of phenothiazine-C 60 (C 60 N þ -MePH and Ph(4)C 60 ) systems. 23,24) The effects of magnetic processing in C 60 N þ -MePH systems are probably attributable to the MHD mechanism and/or the convective flow of suspensions produced by magnetic forces, since C 60 N þ -MePH clusters have a positive charge. On the other hand, the effects of magnetic processing on Ph(4)C 60 nanostructures are most likely attributable to the magnetic force resulting from the gradient field, since Ph(4)C 60 has no charge.…”

“…On the other hand, the effects of magnetic processing on Ph(4)C 60 nanostructures are most likely attributable to the magnetic force resulting from the gradient field, since Ph(4)C 60 has no charge. 24) Molecular aggregates of dye molecules such as a porphyrin have recently attracted interest because of their unique optical properties, for example, the J-aggregation of a porphyrin derivative that has a hierarchical highly ordered structure. The magnetic orientation of nanorods (4 -12 mm in length) with a J-aggregation of a porphyrin derivative and a rod-shaped J-aggregation oriented parallel to the static magnetic field has been reported.…”

Effects of Strong Magnetic Processing on Orientation and Photoproperties of Gold Nanowires on a Substrate

“…We have reported the effects of magnetic processing on the morphological, electrochemical, and photoelectrochemical properties of electrodes modified with nanoclusters of phenothiazine-C 60 systems [2][3][4]. We have also reported that the magnetic orientation of single-walled carbon nanotubes or their composites using polymer wrapping [5] and nanowires consisting of regioregular poly(3-alkylthiophene) (poly(3-hexylthiophene) [6] and poly(3-butylthiophene) [7]).…”
