biogenic connectivity in proteins is used to inspire a chemical pathway toward mussel‐adhesive mimics. The mussel‐inspired polymerization (MIPoly) exploits the chemically diverse family of bisphenol monomers that is oxidizable with 2‐iodoxybenzoic acid to give bisquinones. Those react at room temperature with dithiols in Michael‐type polyadditions, which leads to polymers with thiol–catechol connectivities
Bisphenol A was oxidized to monoquinone and bisquinone derivatives by Fremy's salt, a radical oxidant, though salcomine and alkali did not catalyze the oxidation by molecular oxygen. Bisphenol A, bisphenol B, and 3,4'-(1-methylethylidene)bisphenol were converted to their monoquinone derivatives in the presence of tyrosinase at 25 degrees C at pH 6.5, but not to the bisquinone derivatives under these

understand conversion of bisphenol A and its related compounds under some chemical and biological environments, oxidation of these compounds was performed. Bisphenol A was oxidized to monoquinone and bisquinone derivatives by Fremy's salt, a radical oxidant; but salcomine and alkali did not catalyze the oxidation by molecular oxygen.

A novel self-accelerating Diels–Alder reaction was developed to construct a fused multicyclic linkage with high rigidity and a large contortion. A novel stoichiometric imbalance-promoted step-growth polymerization was developed based on this reaction to prepare PIMs with high molecular weights, high specific surface areas, and H2 separation performance.
