A novel, ladder-like silsesquioxane with pendant methacryl moieties is synthesized, and pristine micropatterns are obtained through a simple spin-coating method, as presented by Seung-Sock Choi, Albert S. Lee, He Seung Lee, Hyeon Yeol Jeon, Kyung-Youl Baek, Dong Hoon Choi, and Seung Sang Hwang on page 5012. Without the need for any photoinitiators, ladder-like structured silsesquioxanes are photocured to give high surface modulus values exceeding 8 Gpa. The use of these ladder-like structured materials is shown to vastly simplify the processing of thermally stable, high-modulus micropatterned films.
