Estimating the term…
Precursor solutions for radiation patternable coatings are formed with an organic solvent and monoalkyl tin trialkoxides in which the water content of the solvent is adjusted to be within 10 percent of a selected value. Generally, the water content of the solvent is adjusted through water addition, although water removal can also be used. In some embodiments, the adjusted water content of the solvent can be from about 250 ppm by weight to about 10,000 ppm by weight. With the appropriate selection of ligands, the adjusted precursor solutions can be stable for at least about 42 days, and in some cases at least 8 months.
A solution comprising a mixture of an organic solvent with a selected water content and a first monoalkyl tin trialkoxide (RSn(OR′)3), wherein the solution has a tin concentration from about 0.004 M to about 1.0 M and wherein the selected water content is at least about 250 ppm by weight and wherein the solution is stable for at least 42 days, wherein R and R′ are independently a hydrocarbyl ligand with one or more carbon atoms optionally substituted with one of more heteroatom functional groups, wherein the hydrocarbyl ligand comprises an alkyl, an aryl, an alkenyl, or a cycloalkyl group with 1-31 carbon atoms.
