The effects of the influence magnetic field on luminescence intensity methoxypolyphenylene vinylene (MEH-PPV) films at various air pressures above samples are investigated. An inversion sign effect was detected with a smooth change in oxygen concentration system. Based balance equations, theoretical model processes is proposed that takes into account formation populations triplet (T) excitons M...

Supramolecular electrets consisting of poly(4-vinylpyridine) (P4VP) and conjugated molecules of phenol, 2-naphthol and 2-hydroxyanthracene were investigated for non-volatile transistor memory applications. The memory windows of these supramolecular electret devices were significantly enhanced upon increasing the π-conjugation size of the molecule. A high ON/OFF current ratio of more than 10(7) ...

The concept of a double-bonded pancake bonding mechanism is introduced to explain the extremely short π-π stacking contacts in dimers of dithiatriazines. While ordinary single pancake bonds occur between radicals and already display significantly shorter interatomic distances in comparison to van der Waals (vdW) contacts, the double-bonded pancake dimer is based on diradicaloid or antiaromatic ...

Functional molecules possessing photoluminescence (PL) and liquid-crystalline (LC) behaviors, known as photoluminescent liquid crystals, along with a small molecular structure, have attracted significant attention. Fluorinated tolane skeletons are π-conjugated structures, which promising candidates for such functional molecules. These structures were revealed to exhibit strong PL in solid state...
