中文摘要： 本项目拟以Schiff碱和卟啉的铂配合物为发光材料制备静电喷雾有机电致发光二极管(OLEDs)。拟合成D-π-A-π-D (D&A)型的两极性分子，来调节发光波长及电子、空穴传输能力；通过重金属铂实现三线态磷光发射，提高发光量子产率；设计带有立体位阻的多枝状或者长烷烃配合物，来避免或减少激发态的浓度淬灭。在器件制备中，使用新型静电喷雾沉积(Electrospray deposition, ESD) 技术取代常用的蒸镀法和旋涂法来制备廉价、高效、均匀的多层薄膜。这种两极性可见/近红外电致磷光静电喷雾器件(D&A-Vis/NIR-ESD-PHOLEDs)，预计可实现从绿光、黄光、红光、近红外光和白光的发射。

英文摘要： Here, we design a series of platinum complexes based on Schiff bases and porphyrins with bulky substituents and electron donor-π-acceptor-π- donor (D&A) groups to harvest both singlet and triplet excitons, reduce the aggregation or excimer formation and balance the holes and electrons transporting, which may improve the performance of the phosphorescent organic light-emitting devices (PHOLEDs). The thin film will be fabricated by novel electrospray deposition technique, which gave low cost, high efficience and uniform film in the earlier research. We anticipate these devices can emit green, yellow,red, near-infrared and white light, which can be called as D&A-Vis/NIR-ESD-PHOLEDs. To research on these novel platinum complexes and electrospray deposition device, we can get some new materials and film preparing methods for the small molecule of visible/NIR PHOLEDs and expand the applicable scope of electroluminescent devices. Therefore, it has important theoretical significance and potential application value.
