  NOVEL DONOR-ACCEPTOR FLUORENE SCAFFOLDS: A PROCESS AND USES THEREOF

  摘要：

  本发明涉及新型供体-受体芴化合物，可用于制造电致发光器件，并提供了制备这些新化合物的方法。更具体地说，本发明涉及胺供体和腈/酯受体芴，芴酮的π-共轭系统及相关化合物，制备这些化合物的方法包括将芴氧化为相应的芴酮，并将它们用于制备有机电子器件，例如有机发光二极管（OLEDs），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。这些化合物是通过在有机溶剂中在碱的存在下，用含有亚甲基羰基基团的环状酮与2H-吡喃-2-酮在孤立或刚性构象下反应而制备的。本发明还涉及一种新的概念和方法，以克服9-未取代芴基有机发光二极管中的“绿色发射缺陷”问题，该问题是由于芴转化为主要在绿黄色区域发射的芴酮而引起的。在本发明中，我们将供体-受体取代基放置在这样的位置，使得供体-受体芴酮的发射在蓝色区域（而不是绿黄色区域）显示，从而提高了蓝色纯度并克服了绿色发射缺陷问题。

  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 π-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 occurs 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.

  The "green emission defect" (GED) produced by fluorenones has significantly retarded the commercial scope of fluorene-based B-OLEDs. In this paper, for the first time, it is demonstrated that the "green light" emitting fluorenones 7 can be converted to "blue light" emitting fluorenones 10 by appropriate positioning of donor-acceptor and chromophoric groups onto the fluorene/fluorenone backbone. Additionally, we report an elegant highly rapid synthetic route for donor-acceptor fluorenes and fluorenones at room temperature with excellent yields.
