Research Abstract

In this study, the syntheses of highly regio-selective substituted cellulose derivative and the development of the advanced material from them using their self assembly and their ability for the metal complex formation were investigated.
First, novel reagents for tritylation of cellulose, 4-alkoxytrityl chlorides with different, alkyl chains, were synthesized by three reaction steps in high yields. Cellulose was reacted with theses reagents in LiCl/DMAc at 70℃ to afford a series of 6-O-(4-alkoxytrityl)celluloses with a high degree of substitution (0.94〜0.99) in high yield.
Next, 6-O-(4-stearyloxytrityl) cellulose acetate Langmuir-Blodgett films were prepared and characterized. This cellulose derivative formed Z-type multilayer films, although Y-type cellulose multilayer films have been reported. From AFM and ellipsometry measurements, it was suggested that long alkyl chain of it in LB film has a folding structure.
On the other hand, 6-O-alkylcelluloses, which were synthesized by a ring-opening polymerization using glucose orthoester derivative, were subject to prepare monolayer and multilayer film to compare with 6-O-(4-stearyloxytrityl) cellulose. 6-O-stearylcellulose also formed most stable monolayer film. This indicates that trityl group in the monoalkylated tritylcellulose was not essential to a form monolayer film,
Finally, a fnctional group containing metal, that is, 3-ferrocenoylpropanoyl group, was introduced at C-2 or C-3 position in 6-O-(4-stearyloxytrityl) cellulose. The cellulose derivative prepared, gave X-type multilayer films. From cyclic voltammogram of the film on a gold electrode, electron transfer between the cellulose film and the electrode surface was observed. The LB films from this cellulose derivative might be useful for an electroluminescence
