Diimine compound (DC) consists of aryl diimine center substituted by bis(2,6-dialkylaniline), and hydroxyl, amine and alkoxy groups substituted on 4 aryl rings, which may facilitate the formation of promising self-assembled architectures through intermolecular pi-pi stacking interaction and hydrogen bonds. DC self-assemblies contain a large number of phenolic hydroxyl groups, which may provide promising platforms for in-situ generation and accommodation of metal nanoparticles. Since diimine center of DC provides reactive sites for easily coordinating late-transition metal, each DC assembly composed of numerous building blocks can incorporate stoichiometric amount of metals, forming bulky catalysts towards olefin polymerizations. Targeted to that, herein, a novel type of multifunctional supramolecular hosts has been fabricated using DC as building blocks for ethylene polymerizations. |
