Monolayers of regioselectively substituted cellulose cinnamates having photo-sensitivity were prepared on the water surface. Then, they were deposited onto nematic ordered cellulose (NOC) templates having unique surface properties to successfully induce establishment of ordered three-dimensional, hierarchical structures of bacterial cellulose nanofibers secreted from Gluconacetobacter xylinus, epidermal cells as well as a biomineral of calcium phosphates by the attachments and subsequent culture for their growth. In this article, the regioselectively substituted cellulose cinnamates as a molecule was employed to compress the monolayer on water surfaces, before it was deposited onto NOC in comparison of glass slide surfaces. The result at first indicated that the structure of each solid monolayer was different depending on regioselectivity of the substituent. In particular, the 2,3-O-subsitituted derivative was found to form a homogeneous monolayer. In addition, the molecular orientation on the surface was induced by NOC templates, similarly to the previous cases above. This paper also refers to a UV-irradiation effect to the oriented structure.
