diarylmethanes were directly oxidized into diaryl ketones in 67%–98% yields. Additionally, various secondary alcohols were also transformed into the desired products in 48%–98% yields. Importantly, the catalytic system in the absence of any organic solvent, surfactant, or phase transfer agent, had a wide substrate scope and a high tolerance for various functional groups.

NMR, FT-IR, UV-vis, PL spectroscopy, DSC, TGA, CV and MALDI-TOF. Multilayer organic light-emitting diode (OLED) devices based on these materials were fabricated to investigate their hole-transport properties. The electroluminescent properties of these molecules showed excellent performance in the devices. CFT-based OLED devices exhibited the best performance with a low turn on voltage of 3 V, a maximum
通过UllMAnn偶联和Suzuki交叉偶联反应合成了一系列以螺芴为中心,咔唑和噻吩连接的分子(CFT,TCFT和CFTFC),并通过1 H NMR,13 C NMR,FT-IR,UV-可见光,PL光谱,DSC,TGA,CV和MALDI-TOF。制造了基于这些材料的多层有机发光二极管(OLED)器件,以研究其空穴传输性能。这些分子的电致发光特性在器件中显示出出色的性能。基于CFT的OLED器件在3 V的低开启电压,10 100 cd m -2的最大亮度下表现出最佳的性能最大发光效率为11.30(cd A -1)。这项工作为在高效OLED应用中使用螺二芴半导体提供了机会。

The efficient synthesis of a new tripodal platform based on a rigid 9,9′-spirobifluorene with three acetyl protected thiol groups in the positions 2, 3′ and 6′ for deposition on Au(111) surfaces is reported. The modular 9,9′-spirobifluorene platform provides both a vertical arrangement of the molecular rod in position 7 and its electronic coupling to the gold substrate. To demonstrate the validity
