Cross-linked micelles have shown promise as catalyst supports, with improved structural stability, catalyst recovery, and chemical diversity compared to their uncross-linked counterparts. The physicochemical properties differ when the shell or core-domain is cross-linked, impacting catalysis. Initially designed for single catalytic entities, shell cross-linked micelles and core cross-linked micelles have since been used for compartmentalizing catalysts in non-orthogonal tandem catalysis and as phase transfer agents in biphasic catalysis. Challenges and new design trends for advanced micellar nanoreactors are currently being discussed in this field.
Cross-linked micelles have emerged as promising catalyst supports over the past two decades due to their improved structural stability, chemical diversity in multiple domains, and catalyst recovery compared to their uncross-linked analogues. We highlight the different physicochemical properties that arise by cross-linking the shell or core-domain and the subsequent impact on catalysis. Both, shell cross-linked micelles (SCMs) and core cross-linked micelles (CCMs) were initially designed to include one catalytic entity. Later on, SCMs were used to compartmentalize catalysts for non-orthogonal tandem catalysis while CCMs were investigated as phase transfer agents in biphasic catalysis. Current challenges in this field and new design trends for advanced micellar nanoreactors are discussed.
