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.
