Capability of exciplex energy transfer through a spacer was investigated using three exciplex-forming solid mixtures which contained the well-known electron accepting 2,4,6-tris[3-(diphenylphosphinyl)phenyl]-1,3,5-triazine and appropriately designed bipolar cyanocarbazolyl-based derivatives functionalized by attachment carbazolyl, acridanyl or phenyl units. These novel were used as both donor. Efficient organic light-emitting diodes with electroluminescence in cyan-yellow region maximum...
Two derivatives of phenyl pyrimidine as acceptor unit and triphenylamino or 4,4'-dimethoxytriphenylamino donor groups were designed synthesized emitters for organic light-emitting diodes (OLEDs) aiming to utilize triplet excitons in the electroluminescence. Thermogravimetric analysis revealed high thermal stability compounds with 5% weight loss temperatures 397 438 °C. The theoretical estimations photophysical data show contributions local excited charge transfer states into emission....
A new family of symmetrical fluorene derivatives with different types substituents attached to the C-2 and C-7 positions core synthesized by Sonogashira coupling reactions is reported. The electronic structures properties compounds investigated means photoelectron emission spectroscopy, UV-Vis absorption photoluminescent spectroscopy as well DFT TD-DFT theoretical calculations are discussed. It shown that nature influences π-conjugation molecules. No intermolecular charge transfer within...
Poly(2-aminothiazole) is a little-studied conducting polymer with sulfur and nitrogen heteroatoms in the aromatic ring, which reveals prospects for application various fields. We studied conditions of chemical synthesis poly(2-aminothiazole) its composite graphene oxide an aqueous solution, as well electrochemical deposition on electrode surfaces – Pt SnO2. The structure was investigated by SEM FT-IR spectroscopy. A quantum-chemical calculation using semi-empirical PM7 method carried out....
Thin films of poly(o-anisidine)-graphene oxide nanocomposites were formed by electrochemical polymerization on the transparent SnO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> substrates. It was found that doping poly(o-anisidine) with graphene leads to significant changes in film morphology and electronic structure conjugated polymer.
