Polyurethane-Type Poly[3]rotaxanes Synthesized from Cyclodextrin-Based [3]Rotaxane Diol and Diisocyanates

Front Cover: Synthesis and property evaluation of cyclodextrin (CD)-based polyurethane-type poly[3]rotaxane is studied. The polyaddition between acetylated CD-based [3]rotaxane diol and various di-isocyanates affords polyurethanes, and the subsequent deprotection of acetyl groups on CD units generate hydroxyl groups, inducing drastic property change. More details can be found in article 2400441 by Yosuke Akae and Patrick Theato.
