Precursor structure of chemically modified Al(O-sec-Bu)3 with ethyl acetoacetate or diethanolamine, dissolved in diethylene glycol (DEG), ethylene glycol monoethyl ether (EGE), and sec-butyl alcohol (sec-BuOH), was investigated using 27AlNMR. 27AlNMR spectra revealed that the reaction of DEG or EGE with Al(O-sec-Bu)3 led to the formation of six-coordinated structural units. The precursor structure of Al(O-sec-Bu)3 modified with ethyl acetoacetate in EGE, which consisted of six- and five-coordinated structural units, was almost the same as that in DEG, but different from that in sec-BuOH, where four-coordinated structural units were also observed. In Al(O-sec-Bu)3 modified with diethanolamine, five- and six-coordinated structural units were present in all the solvents used in this study and the effect of solvents on the coordination state was very small.
