| Outline of Final Research Achievements |
The self-assembly of a regioselectively functionalized cellulose in a confined two-dimensional interface was investigated, leading to the polysaccharide-based rod-shaped nanostructures mimicking the naturally-occurring chloroplasts. AFM and GIWAXS were demonstrated to reveal the structure of cellulose nanorods. The obtained nanorods having pyro-pheophorbide a chromophores exhibit interesting optical properties, displaying a larger bathochromic shift than their solution and drop-cast film counterparts. The photofunctional utilization of the cellulose nanorods was demonstrated by the photocurrent measurements. Hence, these finding provides an excellent argument in favor of a good strategy for the preparation of two-dimensional polysaccharide-based nanostructures. Furthermore, the colloidal suspension of cellulose nanofiber (CNF)/ nanowhisker (CNW) decorated with concentrated polymer brushes was studied, which can be a promising system for the construction of ordered structure.
