실험 절차

A solution of catechol (5.51 g, 50.0 mmol) and toluene (50 ml) was dehydrated by distilling 10 mL of the solution. Thereafter, 8.13 g (20.0 mmol) of tantalum(V) ethoxide was added to the solution while stirring. The mixed solution was refluxed for 1 hour, and then, while the distillation temperature was 110° C. or higher, distilled until the amount of the solution became half. After the distillation, volatile components of the residual mixed solution were vaporized under reduced pressure by a rotary evaporator. The residual solid content was further heated to 100° C. under vacuum using a vacuum dryer so that the remaining volatile components were completely removed. The solid content (catechol-tantalum complex) was yellow in color. The yield amount was 9.02 g (20.0 mmol), and the yield percentage was 100%. 4.51 g of catechol-tantalum complex was dissolved into 100 mL of 1:4 acetylacetone/toluene to produce a coating liquid.
