Click Functionalization of a Dibenzocyclooctyne‐Containing Conjugated Polyimine

Abstract A conjugated poly(phenyl‐ co ‐dibenzocyclooctyne) Schiff‐base polymer, prepared through polycondensation of dibenzocyclooctyne bisamine (DIBO‐(NH 2 ) 2 ) with bis(hexadecyloxy)phenyldialdehyde, is reported. The resulting polymer, which has a high molecular weight ( M n >30 kDa, M w >60 kDa), undergoes efficient strain‐promoted alkyne–azide cycloaddition reactions with a series of azides. This enables quantitative modification of each …
