Preparation of Multifunctional Hollow Microporous Organic Nanospheres via One-pot Hyper-cross-linking Mediated Self-assembly Strategy

Abstract

Herein we report a universal method for the preparation of multifunctional hollow microporous organic nanospheres (H-MONs) using functional aromatic monomers (such as: benzylamine, 2, 2-bipyridine, triphenylamine or carbazole) and polylactide-b-polystyrene (PLA-b-PS) diblock copolymer as precursors based on the one-pot hyper-cross-linking mediated self-assembly strategy. In this method, co-hyper-cross-linking among PS block and various aromatic monomers forms the functional microporous organic shell frameworks, while the degradable PLA block produces the hollow core structure. By introducing functional organic ligands, various metal-loaded or heteroatom-doped H-MONs can be successfully synthesized. Owing to the high special surface area, robust organic framework, hierarchically porous structure, these multifunctional H-MONs exhibited excellent catalytic activity or high adsorption capacity for radioactive iodine. The proposed one-pot strategy may provide a general approach to produce a variety of functional H-MONs for various applications in the future.
