NANOMETER PPV FILMS/SYNTHETIC DYES CONVERTED AT LOW TEMPERATURES: AZOCHROMOTROPIC SULFANIC ACID; INDIGO CARMINE; ORANGE 2 SODIUM SALT; METHYL ORANGE AND NITRAZINE YELLOW

Abstract

Light-emitting polymers, like conjugated polymers, are attractive for fundamental physics and technological applications. Poly(p-phenylenenovinylene) (PPV) is an excellent choice for electroluminescent and photovoltaic devices, although it presents challenges due to its insolubility in organic solvents. A conventional route to obtain PPV involves a thermal process at high temperatures, but with increased structural defects. An innovative alternative, with lower temperature and treatment time, was proposed using synthetic dyes instead of DBS without compromising the properties of PPV.
