Functional Perfluoroalkyl Polyhedral Oligomeric Silsesquioxane (F-POSS): Building Blocks for Low Surface Energy Materials
Abstract
Fluorinated polyhedral oligomeric silsesquioxanes (F-POSS), a subclass of POSS, were recently synthesized and have proven to be an excellent low-surface energy material for superhydrophobic and oleophobic surfaces. These F-POSS compounds consist of a silicon-oxide core with a periphery of long chain fluorinated alkyl groups ranging from 6-12 carbon atoms in length. Herein, a disilanol perfluoroalkyl polyhedral oligomeric silsequioxane (F-POSS-(OH)2) has been synthesized via a viable multi-step synthesis (52% yield). These incompletely condesened structures were readily reacted with a variety of dichlorosilanes to produce functional F-POSS structures. Structures were confirmed with multinuclear NMR (1H, 13C, and 29Si) and found to possess different solubility properties compared to the closed-cage F-POSS. These novel structures can be used as the initial building blocks for the development of new superhydrophobic and oleophobic materials.
