The invention provides an organic light-emitting material with anthracene structure and an organic light-emitting device with anthracene structure and belongs to the technical field of organic photoelectric materials. The organic light-emitting material with anthracene structure comprises anthracene rings that are a blue light-emitting material parent nucleus structure having excellent performanceand having high triplet state energy level and wide energy gap; by connecting benzimidazole groups to molecules, the material is provided with improved electron transport capacity so that carrier transport is balanced. Compared with the prior art, the organic light-emitting material with anthracene structure applied to organic light-emitting devices, particularly as blue objective material in a light-emitting layer has higher luminous efficiency.

The relationship between molecular structure and electronic properties in dicyanovinyl substituted acceptor-donor-acceptor chromophores

In this contribution we describe a combined experimental and theoretical study of the relation between the molecular structure and the electronic properties of conjugated donor-acceptor type chromophores for light-harvesting applications. A series of model systems was synthesized where a central anthracene (electron donor) is connected to dicyanovinyl units (electron acceptor) through a π-conjugated spacer. The study of the redox and optical properties of these chromophores and of reference compounds without dicyanovinyl units allows us correlate the electronic properties to the presence of the electron withdrawing groups and the molecular conformation. Comparison with calculated electronic structure shows that the construction of chromophores that consist of electron donating and accepting units does not always follow the simple rules that are generally used in the design of such molecules. The results show a subtle relation between the charge transfer character and the geometry of the molecules. In some cases this leads to significant contribution of charge transfer excitation to the absorption spectra of some chromophores while such contributions are completely absent in others.
Suzuki-Miyaura Micellar Cross-Coupling in Water, at Room Temperature, and under Aerobic Atmosphere

Recently, oxygen-equilibrated water solutions of Kolliphor EL, a well-known surfactant, have been seen to form nanomicelles with oxygen-free cores. This has prompted the successful testing of the core environment as a green medium for palladium-catalyzed Suzuki-Miyaura cross couplings. The versatility of these conditions is endorsed by several examples, including the synthesis of relevant molecular semiconductors. The reaction medium can also be recycled, opening the way for an extremely easy and green chemistry compliant methodology.
