Abstract

ABSTRACT: A series of nitrogen‐rich porous polyaminal networks (PANs) with five different linkages were prepared through a facile route from cost‐effective starting materials. Each structural unit bears a different number of phenyl and pyrrolyl rings, which are found to be useful for iodine uptake through a physical adsorption mechanism. The PAN3 bearing the 4, 4‐difluoro‐4‐bora‐3a, 4a‐diaza‐ s ‐indacene (BDP) units, which could adsorb iodine by both physical and chemical interaction, achieves an efficient iodine capacity up to 2.81 g/g. Significantly, these new nitrogen‐rich PANs might be useful for capture of other volatile compounds. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2018, 135, 46106. Abstract :
