Molecular insight into a disulfonimide-bearing diol: synthesis, characterisation and access to poly(disulfonimide)s

Abstract

We report an expandable synthetic pathway to an obenzenedisulfonimide-bearing diol that enables the first poly(1,2disulfonimide) polymers. The non-planar highly polar disulfonimide unit in the backbone is predicted to strengthen interchain interactions while maintaining chain separation, highlighting a molecular design strategy for polymers that decouple strong interchain interactions from packing densification.
