“…2 On the other hand, it is inherently difficult to control the coupling selectivity in the polymerization of 2-and/or 6-unsubstituted phenols (ArOH). Various catalysts for the regioselective polymerization of 2-methylphenol have been the most studied, such as copper complexes with 2,6-dimethylpyridine, 3,4 poly(4-vinylpyridine), 5 2-arylpyridines, 6 a mesoporous silica-supported ethylenediamine, 7 and a triazacyclononane. 8 Among them, only the enzyme-model catalyst, i.e.…”
