Design, Synthesis, Characterization, and Evaluation of Boronate Ester-Linked Porous Materials: Covalent Organic Frameworks and Polymers of Intrinsic Microporosity
<p>An array of porous boronate ester-linked materials is presented here. Beginning with evaluation of a series of alkylated covalent organic frameworks (COFs), insight into the influence of alkylation in the hexagonal COF pores on the hydrolytic stability of the B-O linkages led to development of a …
