Abstract:The basic strategy to make a well-defined A-block-B type cellulose derivative consisting of cellulose and a hydrophobic part was established. The model experiments using cellobiose derivatives play an important role in an actual synthesis of A-block-B type copolymer consisting of cellulose and a hydrophobic part with well-controlled length. A new hydrophobic building block, 15-azidopentadecanoyl chloride, was converted from a commercially available15-hydroxypentadecanoic acid. The novel hydrophobic linker, 15-azidopentadecanoyl chloride, was twice introduced into the reducing end of the cellobiosylamine derivative. The structures of the model compounds for A-block-B type copolymer consisting of sugar and non-sugar blocks were characterized by use of nuclear magnetic resonance (NMR) spectroscopy and Matrix Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS).
