Small-molecular luminous material with 1,2-diphenyl acetylene as acceptor unit, and preparation and application thereof

The invention belongs to the technical field of luminous materials and discloses a small-molecular luminous material with 1,2-diphenyl acetylene as an acceptor unit, and preparation and applications thereof. The preparation method includes the steps of adding the 1,2-diphenyl acetylene compound, a nitrogen-containing compound and a catalyst into a reaction container filled with a solvent under protection of an inert gas; performing a heated stirring reaction, cooling and extracting a reaction product, and spin-drying an organic phase and performing chromatography to obtain the small-molecular luminous material with the 1,2-diphenyl acetylene as the acceptor unit. The small-molecular luminous material has single structure and definite molecular weight, achieves intramolecular charge transfer and solves a problem of unbalanced charge carriers in a mono-polar luminous material, simplifies device structure and improves device performance. The luminous material is used in organic light-emitting devices.

Supramolecular ensemble of a TICT-AIEE active pyrazine derivative and CuO NPs: A potential photocatalytic system for sonogashira couplings

The donor-acceptor system 4 having pyrazine scaffold as an acceptor moiety coupled to donor amino groups through rotatable phenyl rings has been synthesized, which formed aggregates in aqueous media, exhibited copper induced restriction to intramolecular rotation, and served as a "not quenched" probe for the detection of copper(II) ions. During this process, the aggregates of derivative 4 acted as reactors and stabilizers for the generation of CuO NPs and themselves became oxidized to form polyamine derivative 6. Interestingly, the oxidized species 6 in combination with copper oxide nanoparticles served as light-harvesting antennas and exhibited excellent photocatalytic efficiency in Sonogashira coupling under mild and eco-friendly conditions (room temperature, aqueous media, aerial conditions, and visible light irradiation).

Sonochemically synthesis of arylethynyl linked triarylamines catalyzed by CuI nanoparticles: A rapid and green procedure for Sonogashira coupling

A simple and green method was performed to the preparation of copper iodide nanoparticles by ultrasound approach. Consequently the synthesis of aryl ethynyl linked triarylamines was carried out through the Sonogashira coupling between iodo-substituted triarylamine and aryl acetylenes in the presence of CuI nanoparticles/Pd(PPh3)2Cl2 as an efficient catalytic system and triethylamine as the base under ultrasonic irradiation. Good to excellent yields of products and short reaction times are some of the important advantages of this solvent free protocol which were attained by both nano CuI and ultrasound conditions.

Synthesis and spectroscopic study of diphenylamino-substituted phenylene-(poly)ethynylenes: remarkable effect of acetylenic conjugation modes

A series of diphenylamino-substituted phenylene-(poly)ethynylenes were successfully synthesized by a combination of Sonogashira coupling and double elimination protocol of β-substituted sulfones. When UV-light was irradiated, the amino-substituted phenylene-(poly)ethynylene emitted strong luminescence. The emission underwent a large bathochromic shift in polar solvent because of stabilization of their charge-separated excited states. Analyses of fluorescence life times of aminoacetylenes revealed that radiationless process was suppressed in the polar solvent CH2Cl2, resulting in high quantum yields.
