Abstract
Clickable POSS glyoxylic aldehydes: A stable octafunctionalized “cubic” silsesquioxane bearing aldehyde functions was successfully prepared and isolated. This clickable hybrid platform readily reacts with oxyamine or hydrazide and provides effective access to multivalent systems. More information can be found in the Communication by S. Ulrich, J.‐Y. Winum et al. on page 17867. [ABSTRACT FROM AUTHOR]
