中文摘要：

通过模板诱导有机发光小分子定位沉积的方法构筑了大面积纳微米尺度的荧光图案.模板是以纳米压印技术构筑的聚合物微结构为阻挡层蒸镀金属,经Lift-off后形成的金属微结构.在模板表面,有机发光小分子与金属区域的结合能大于与裸硅片区域的结合能,因此,选择结构合适的模板可诱导有机发光小分子定位沉积.这种快速制备大面积荧光图案的方法在提高有机光致发光器件的光抽取效率方面具有潜在的应用价值.

英文摘要：

Micro-and nano-scale fluorescent patterns over large area were fabricated by template directed selective deposition of organic luminescent molecules.The template was fabricated by combination of Nanoimprint Lithography（NIL） and metal evaporation and the following ＂lift-off＂ process.In the template,the organic molecules have larger binding energies on the patterned area in comparison to the substrate,so the site-selective deposition of organic molecules can be obtained by choosing proper template.It is a fast means to fabricate large-area fluorescent pattern,which provides the possibility to increase the extraction efficiency of organic light emitting diodes（OLEDs）.
