There is provided a process for forming a contained second layer over a first layer. The process comprises forming the first layer having a first surface energy and then treating the first layer with a photocurable surface-active composition which is a fluorinated ester or fluorinated imide of an α,β-unsaturated polyacid; exposing the photocurable surface-active composition patternwise with radiation resulting in exposed areas and unexposed areas; developing the photocurable surface-active composition to remove the unexposed areas resulting in a first layer having untreated portions in the unexposed areas and treated portions in the exposed areas, where the treated portions have a second surface energy that is lower than the first surface energy; and forming the second layer on the untreated portions of the first layer. There is also provided an organic electronic device made by the process.
提供了一种形成包含第二层覆盖在第一层上的方法。该方法包括形成具有第一表面能量的第一层,然后用光固化表面活性组合物处理第一层,该光固化表面活性组合物是α,β-不饱和聚酸的
氟化酯或
氟化
亚胺;用辐射逐图案暴露光固化表面活性组合物,形成暴露区域和未暴露区域;开发光固化表面活性组合物以去除未暴露区域,从而形成具有未处理部分的第一层在未暴露区域和在暴露区域中具有处理部分,其中处理部分具有第二表面能量,其低于第一表面能量;并在第一层的未处理部分上形成第二层。还提供了一种通过该方法制造的有机电子器件。
