Hydrofluoroethers as Orthogonal Solvents for the Chemical Processing of Organic Electronic Materials

A study was conducted to demonstrate a new approach for chemicalprocessing of organic electronic materials. It was demonstrated that the approach is based on the use of fluorous solvents, segregated hydrofluoroethers (HFE). The study also demonstrated that that processing organic electronics, using HFEs under extreme conditions, such as boiling temperatures, does not cause any dissolution, cracking, delamination,or other unfavorable physical or chemical change. The study also demonstrated that the use of fluorous solvents enables simple photolithographic patterning of organic electronic materials. It was shown that fluorous solvents are perfluorinated on very highly fluorinated liquids, which are immiscible with organic solvents and water.
