Dioxaborines as organic n-semiconductors, a process for the production of semiconductors utilizing dioxaborines, and a semiconductor component, a field effect transistor, and a diode having a dioxaborine are provided. Dioxaborines have a conjugated π-system that carries two terminal six-membered dioxaborine heterocycles that are electronically linked to one another via the central π-system. The compounds have good electron mobility and very good reversibility of redox behavior and are therefore suitable as organic semiconductors in electronic semiconductor components. Processes for manufacturing the electronic semiconductor components utilize the dioxabroines.
The present invention relates to polymers comprising a repeating unit of the formula (I), and their use in electronic devices. The polymers according to the invention have excellent 5 solubility in organic solvents and excellent film-forming properties. In addition, high charge carrier mobilities and high temperature stability of the emission color are observed, if the polymers according to the invention are used in polymer light emitting diodes (PLEDs).
The invention is related to anti-viral compounds, compositions containing such compounds, and therapeutic methods that include the administration of such compounds, as well as to processes and intermediates useful for preparing such compounds.
(v-2D-COF-NO1 and v-2D-COF-NO2) with trans and cis configurations of benzobisoxazole. Interestingly, the isomeric benzobisoxazole linkers endow the two v-2D-COFs with distinct optoelectronic and electrochemicalproperties, ranging from light absorption and emission to charge-transfer properties. When employed as the photocathode, v-2D-COF-NO1 exhibits a photocurrent of up to ∼18 μA/cm2 under AM 1.5G irradiation
乙烯/烯烃连接的二维共价有机框架(v-2D-COFs)已成为先进的半导体材料,具有出色的面内共轭、高化学稳定性和精确可调的电子结构。探索用于 v-2D-COF 网状结构的新连接化学仍处于起步阶段且具有挑战性。在此,我们提出了一种固态苯并二恶唑介导的羟醛缩聚反应,用于构建具有反式和顺式的两种新型异构苯并二恶唑桥联 v-2D-COF(v-2D-COF-NO1 和 v-2D-COF-NO2)苯并双恶唑的构型。有趣的是,异构的苯并二恶唑接头赋予了两种 v-2D-COF 不同的光电和电化学特性,从光吸收和发射到电荷转移特性。当用作光电阴极时,v-2D-COF-NO1 在 AM 1.5G 辐照下在 -0.3 V vs 可逆氢电极 (RHE) 下表现出高达 ∼18 μA/cm 2的光电流,这是 v- 值的两倍2D-COF-NO2 (~9.1 μA/cm 2 )。以 Pt 为助催化剂,v-2D-COF-NO1
