Precise Tuning of Cationic Cyclophanes toward Highly Selective Fluorogenic Recognition of Specific Biophosphate Anions
摘要:
Cationic cyclophanes with bridging and spacer groups possess well-organized semirigid cavities and are able to encapsulate and stabilize anionic species through diverse molecular interactions. We highlight the precise tuning of functionalized cyclophanes toward selective recognition of AMP, GTP, and pyrophosphate (PPi) using fluorescence, NMR spectroscopy, and density functional theory (DFT).
Synthesis and antifungal activity of new 1-vinylimidazoles
摘要:
Carbonyl compounds I were subjected to an imidazole transfer reaction with N,N'-sulfinyldiimidazole or N,N'-carbonyldiimidazole to obtain the diimidazole II and the monoimidazole III. Various 1-vinylimidazoles IV, derived from o-hydroxyacetophenones by imidazole transfer reaction, were alkylated to furnish the title compounds V. The structure-activity relationships of these 1-vinylimidazole compounds V are described.

[EN] The invention provides a diimidazole compound and an organic electroluminescent device using the same and more particularly, the diimidazole compounds according to the invention have excellent blue luminescent characteristics and hole transmission characteristics and at the same time, they not only can be used as a blue luminescent material or used as a host to a variety of phosphorescent or fluorescent dopants such as red, green, blue and white but also enable high efficient luminescence when applied to organic electroluminescent devices and can confer such performances as low voltage, high brightness and long lifetime. [FR] La présente invention concerne un composé diimidazole et un dispositif organique électroluminescent qui comprend ce dernier. Plus particulièrement, les composés diimidazole selon l'invention présentent d'excellentes caractéristiques de luminescence bleue et des caractéristiques de transmission des trous, de surcroît on peut les utiliser non seulement en tant que matière luminescente bleue ou en tant qu'hôte pour divers dopants phosphorescents ou fluorescents tels que le rouge, le vert, le bleu et le blanc mais ils produisent également une luminescence très efficiente lorsqu'on les utilise dans des dispositifs organiques électroluminescents et peuvent conférer des propriétés telles qu'une faible tension, une haute luminosité et une longue durée de vie.
