Vorschrift

A solution of catechol (3.30 g, 30.0 mmol) and toluene (45 ml) was dehydrated by distilling 5 mL of the solution. Thereafter, 4.08 g (20.0 mmol) of aluminum(III) isopropoxide was added to the solution while stirring. The mixed solution was refluxed for 1 hour, and then, while the distillation temperature was 100° 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-aluminum complex) was green in color. The yield amount was 3.78 g (20.0 mmol), and the yield percentage was 100%. 1.89 g of catechol-aluminum complex was dissolved into 100 mL of 1:4 acetylacetone/toluene to produce a coating liquid.
