Fabrication and Characterization of Electronic and Optical Properties of Polyaniline Nanopatterns.

The authors conducted polyaniline (HA) polymerization on a micro-scale patterned Si water and nano-scale patterned Al surface. Polymerization was performed using a microliter solution droplet made of aniline, HCI and oxidation agent ammonium peroxodisulfate (APS). The droplet was dropped on a flat Si wafer, a micro-patterned Si wafer and a nanostructured Al surface.

Photoluminescence characterization of polythiophene films incorporated with highly functional molecules such as metallophthalocyanine.

The photoluminescence (PL) of conducting polymer polythiophene (PT) films incorporated with metallophthalocyanines (PcMs) such as CuPc, MgPc, FePc, LiPc, and CoPc was studied by PL and time-correlated single photon counting (TCSPC) measurements. Polymer films were prepared by electrochemical polymerization and PcMs migrated into the polymer films by a diffusion method using acetonitrile or toluene as a solvent to dissolve the PcMs. The wavelength of PL emission peaks changed significantly depending on the solvent used in the doping process.
