Functionalized microporous organic nanotube networks as a new platform for highly efficient heterogeneous catalysis

Abstract

In this paper, we report a novel synthesis of amino-functionalized microporous organic nanotube networks (NH₂-MONNs) by combination of hyper cross-linking and molecular templating of multicomponent bottlebrush copolymers. The amino-modified MONNs constructed from a unique trimodal micro, meso and macroporous architecture and flexible frameworks possess a specific surface area of 936 m² g⁻¹ and a pore volume of 1.67 cm³ g⁻¹. Owing to the large surface area, good multi-porosity interconnectivity and excellent swelling properties in organic solvents, the resultant NH₂-MONNs show highly efficient heterogeneous catalysis and excellent reusability in the Knoevenagel condensation and Henry reaction.
