We report on the first experimental and theoretical investigations of ultrafast intramolecular energy transfer for a novel class of highly luminescent materials-nanostructured organosilicon luminophores (NOLs). For this purpose we designed, synthesized an

Paragraph 0189; 0193-0195, (2019/08/06)
The present invention relates to an organic compound having an amine core substituted with three aromatic rings, wherein a part of the three aromatic rings is substituted with a functional group capable of a solution process while the rest of the three aromatic rings is substituted with a hetero-aromatic functional group; and a light-emitting diode and a light-emitting device having the organic compound applied to a light-emitting layer. The organic compound may be used to the light-emitting layer to eliminate the HOMO energy barrier between the light-emitting layer and another light-emitting layer adjacent thereto. Also, the organic compound, when it forms a light-emitting layer in combination with light-emitting particles, may improve interfacial properties between the light-emitting layer and an adjacent layer to improve morphological properties of the light-emitting diode. The organic compound of the present invention, by allowing holes and electrons to be transported and implanted into a light emitting material layer in a balanced manner, may implement light-emitting diodes and light-emitting devices with improved luminance efficiency and capable of low-voltage driving.(110) First electrode(120) Second electrode(AA) Smooth interface morphology ↑COPYRIGHT KIPO 2019

Pyrazinoquinoxaline-based building blocks were incorporated into both π-conjugated dendrimers and polymers. The dendrimers were synthesized using a convergent/divergent approach whereas the donor/acceptor copolymers were synthesized via Stille cross-coupling reactions. The structurally defined dendrimers and the π-conjugated polymers were investigated with respect to their optical and electronic properties as well as their performance in photovoltaic devices. Because of the presence of the electron-deficient pyrazinoquinoxaline moiety, the absorption spectra of the materials under investigation were red-shifted with respect to the all thiophene-containing materials. Power conversion efficiencies up to 1.7 and 0.8% were obtained from blends of second-generation dendrimers and polymers with PC71BM, respectively.
