In contrast to the difunctional bimolecular coupling reaction A2 + B2, a linear difunctional polymer precursor (A2) can also be coupled with a small molecule that does not show obvious difunctional groups (B). However, once one of the telechelic chain ends of the linear polymers reacts with the small molecules, the resulting group can further react with another chain end to form a cyclic polymer. Here we denoted the reaction as A2 + B.
