Fine Wettability Control Created by a Photochemical Combination Method for Inkjet Printing on Self-Assembled Monolayers

Wettability tuning for organic solvents is demonstrated with the combination method, a reversal of the conventional cleavage method. Several advantages are inherent to this method: for example, the syntheses are simple, various surface-active groups can be used, and the reaction proceeds with a low-energy light source.
