Oxidative Copolymerization of o-Hydroxy-m-Phenylenediamine and O- Toluidine - Synthesis, Structure and Properties of Copolymers

Oxidative copolymerization of o-hydroxybenzylidene-m-phenylenediamine and o-toluidine in a solution of sulfuric acid synthesized new copolymers of different composition. Structures of the copolymers obtained were confirmed by IR spectroscopy. It is shown that the copolymers obtained are not fusible materials and acid-soluble materials. The synthesized copolymers have been found to possess sufficient thermostability. The process of decomposition of the copolymers occurs in several stages, the temperature ranges depending on their composition.

Facile Synthesis of Pyrene/Pyrrole Copolymer with Strong Green Fluorescence

The pyrene/pyrrole copolymer (Pn/Py copolymer) has been sucessfully synthesized by the facile chemically oxidative copolymerization. UV-vis and FT-IR spectra are used to investigate the molecular structure of the copolymer. The results show that pyrene and pyrrole units in the copolymer chain are interconnected via α, α-coupling to form a linear structure. At the same concentration, the copolymer solution exhibits the strongest green fluorescence with a maximum emission at 503 nm and a large stokes shift of about 113 nm by fluorescence spectrometer. The excellent fluorescence of Pn/Py copolymer may be due to its better planar molecular structure and higher large π-conjugation, that is confirmed by UV-vis spectra and molecular simulation.
