Abstract
This work reports on the consequences of concatenation of two twin macrocycles on the gelation behavior of coordination polymers obtained via ring-opening metathesis polymerization (ROMP) initiated by 2nd generation Grubbs' catalyst. The influence of concatenation is evaluated by comparison with the behavior of a non-interlocked model complex under the same reaction conditions. The suitability of the choice of the non-interlocked model complex is discussed in terms of molecular structure and effective molarity (EM). It is found that concatenation has a primary role in the gelation process, resulting in lower critical gelation concentrations for the endotopic, interlocked complex compared with the exotopic, non-interlocked one.
