Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructures

Fig. 4 from : Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructures by Takuya Isono et al. Thin-film morphologies of Glc3-b-Sol and Glc4-b-Sol. AFM height images (a, b) and corresponding cross-sectional profiles (c, d) indicating the formation of 6–8-nm-thick horizontal lamellae in Glc3-b-Sol (a, c) and Glc4-b-Sol thin films (b, d). Thin-film samples were prepared by spin-coating the BCO solution onto the hydrophilic surface of a silicon substrate followed by thermal annealing at 85 °C for 1 h. NANOSENSORS PointProbe Plus PPP-NCHR standard silicon tapping mode AFM probes and NANOSENSORS SuperSharpSilicon high resolution silicon AFM probes were used

Discrete block co-oligomers (BCOs) can form highly ordered ultrasmall nanostructures which can be used for lithographic templates. These nanotemplates are promising for the low-cost, large-scale,…
