Abstract

Polysulfonates obtained from SuFEx click reactions can be degraded using DBU as a bifunctional catalyst. A possible mechanism proceeding through the esterification of the R-S(O)-OR′ group is proposed. The degradation process was further utilized to prepare functional polymers such as the AIEgen-ended polymer and a ternary polymer with tunable emission.
