    • The present invention relates to novel donor-acceptor fluorene compounds, which can be used as for the fabrication of electroluminescent devices, and a process of preparing said novel compounds. More particularly, the present invention relates to amine donor and nitrile/ester acceptor fluorenes, fluorenones their p-conjugated systems and related compounds, processes for preparing the said compounds including oxidation of fluorenes to corresponding fluorenones and their use in preparing organic electronic devices such as organic light emitting diodes (OLEDs), photovoltaic/solar cell, Field effect transistors and.other useful electroluminescent devices. The compounds are prepared by reacting 2H-pyran- 2-ones in isolated or rigid conformations with cyclic ketones containing methylene carbonyl moiety in the presence of a base in- an organic solvent.The present invention also relates to a new concept and approach to overcome the problem of 'Green emission defect' in 9- unsubstituted fluorene-based organic light emitting diodes which occurrs due to the conversion of fluorenes to fluorenones that show emission mainly in green-yellow region. In the present invention we have placed donor-acceptor substituents in such a way that donor- acceptor fluorenones show emission in the blue region (instead of green-yellow region) thus improving the blue colour purity and overcoming the problem of green emission defect.
    • 本发明涉及可用于制造电致发光器件的新型供体 - 受体芴化合物,以及制备所述新型化合物的方法。 更具体地,本发明涉及胺供体和腈/酯受体芴,芴酮其p共轭体系和相关化合物,制备所述化合物的方法,包括将芴氧化成相应的芴酮,以及它们在制备有机电子器件中的用途, 有机发光二极管(OLED),光伏/太阳能电池,场效应晶体管和其他有用的电致发光器件。 该化合物通过在分离或刚性构象中的2-吡喃-2-酮与含有亚甲基羰基部分的环酮在有机溶剂中的碱存在下反应制备。本发明还涉及克服的新概念和方法 由于芴转化为芴酮而发生的9-未取代的基于芴的有机发光二极管中的“绿色发光缺陷”问题,主要表现在绿黄色区域。 在本发明中,我们以供体 - 受体芴酮在蓝色区域(而不是绿 - 黄色区域)中显示发射的方式放置了供体 - 受体取代基,从而提高了蓝色纯度并克服了绿色发光缺陷的问题。

    • A system and method is described for controlling flight trajectories of at least two flying vehicles towards goal positions. The system includes at least two flying vehicles with onboard inertial measurement units for determining and updating orientation, angular velocities, position and linear velocities of the at least two flying vehicles, a motion capture system to detect current position and velocity of each of the at least two flying vehicles, and a base controller in communication with the motion capture system and in communication with the plurality of flying vehicles. The base controller calculates for each of the flying vehicles, at predetermined intervals of time, optimum trajectory paths using piece-wise smooth polynomial functions, applying weighting factors, and enforcing overlap constraints.
