Method for inhibiting the oxidation of VO(acac)2 in solution |
| abstract |
The present invention provides a method to effectively inhibit the oxidization of VO(acac) 2 in solution for months. It is believed that VO(acac) 2 forms a π-complex with as many as three allylic alcohols which precludes reaction with any oxygen in the system. Although saturated and homo-allylic alcohols were also tested, this effect appears only in the allylic-alcohol based solutions. This ability to inhibit oxidation of VO(acac) 2 allows these solutions to be used for making thermochromic VO 2 film much more easily and economically as it avoids the requirement of operating under low oxygen level conditions. Thus the present invention provides a method of stabilizing vanadium oxyacetylacetonate (VO(acac) 2 ) in solution against oxidation for extended periods of time, comprising the steps of mixing the oxyacetylacetonate precursor in an allylic alcohol prior to spin-coating for VO 2 film formation. The allylic alcohol may be β-methallyl alcohol. Alternatively, the allylic alcohol may be any one of 4-buten-2-ol, 2-buten-1-ol, 1-penten-3-ol, 2-hexen-1-ol and 1-hexen-3-ol. |
