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

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, and high-throughput production of sub-10 nm nanomaterials and nanodevices. However, work-intensive synthetic routes can be an obstacle to their practical application. *

In “Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructures” Takuya Isono, Ryoya Komaki, Chaehun Lee, Nao Kawakami, Bian J. Ree, Kodai Watanabe, Kohei Yoshida, Hiroaki Mamiya, Takuya Yamamoto, Redouane Borsali, Kenji Tajima and Toshifumi Satoh report the development of a readily available monodisperse and discrete block co-oligomer (BCO) system consisting of hydrophilic sugars and hydrophobic terpenoids that is capable of forming various self-assembled nanostructures with ultrasmall periodicity.*

The authors believe that the BCOs presented in their publication have the potential to contribute to accelerating applied research of solid and solution state self-assembly of discrete and monodisperse BCOs, thereby expanding their application scopes in various fields of not only the nanolithography but also organic devices, separation materials, coatings, etc.*

NANOSENSORS™ PointProbe® Plus PPP-NCHR standard tapping mode AFM probes and SuperSharpSilicon™  SSS-NCHR high resolution (typical AFM tip radius 2nm)  silicon AFM probes for tapping mode/non-contact mode applications were used for the atomic force microscopy (AFM) phase images presented in the article.

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.
