Multidimensional Generation of Combinatorial Organic Arrays by Selective Wetting Inscription

Based on selective wetting inscription, a highly parallel and error-proof platform is developed to integrate different classes of solution-processed organic elements into 2D and 3D combinatorial arrays with high resolution. By simple solution coating, disparate elements can be precisely self-registered in a pattern-by-pattern or pattern-on-pattern fashion within the framework of the wetting transition as a length scale.
