摘要:
在这项工作中,基于二苯胺基的苯并[4,5]噻吩并[3,2- b ]苯并呋喃(BTBF)核,BTBF-DPA,被合成并系统地研究了一种新型的空穴传输材料(HTM)。BTBF-DPA显示出高的载流子迁移率,良好的热稳定性和高达3.99 eV的三重态能量。制备了使用BTBF-DPA的绿色磷光有机发光二极管(PhOLED),该有机发光二极管具有出色的电致发光性能,具有2.4 V的低开启电压,123.6 cd A -1的最大电流效率(CE),功率效率(PE) )为136.6 lm W -1,外部量子效率(EQE)为34.1%。带有BTBF-DPA的红色PhOLED还显示出最大PE为40.1 lm W -1,EQE为24.9%,开启电压为2.3V。此外,蓝色荧光OLED在10000 cd m处表现出的最大PE为4.9 lm W -1,EQE为5.2%,小效率滚降为11.5%。−2。具有BTBF-DPA

A new bulky biarylphosphine ligand (L8) has been developed that allows the Pd-catalyzed C–O cross-coupling of a wide range of aryl halides and phenols undermilderconditions than previously possible. A direct correlation between the size of the ligand substituents in the 2′, 4′, and 6′ positions of the nonphosphine containing ring and the reactivity of the derived catalyst system was observed. Specifically
palladium‐catalyzed intramolecularoxidativeCH/CH cross‐couplingreaction. This reaction provides a variety of π‐conjugated molecules bearing heteroatoms, such as nitrogen, oxygen, phosphorus, and sulfur atoms, and a carbonyl group. The π‐conjugated molecules were synthesized efficiently, even in gram scale, and larger π‐conjugated molecules were also obtained by a double CH/CH cross‐couplingreaction and successive
含杂原子的阶梯型π共轭分子的合成通过钯催化的分子内氧化性下成功地实现了 H / C ħ交叉偶联反应。该反应提供了各种带有杂原子(例如氮,氧,磷和硫原子)和羰基的π共轭分子。π共轭分子有效地合成,即使在克规模,以及较大的π共轭分子也由双C所得 H / C ħ交叉偶联反应和连续氧化cycloaromatization。
