A Simple and Sequential Strategy for the Introduction of Complexity and Hierarchy in Hydrogen‐Bonded Organic Framework (HOF) Crystals for Environmental Applications
AI summary Read the abstract
Scientists developed a new type of porous crystalline material called a hydrogen-bonded organic framework (HOF) that can trap microplastics and oils from water, demonstrating a potential new approach for water decontamination. The material was engineered to form hierarchical structures without complex surface treatments, making the fabrication process relatively accessible for scale-up.
Abstract Hydrogen‐bonded organic frameworks (HOFs) are a new class of crystalline porous organic molecular materials (POMMs) with great potential for a diverse range of applications. HOFs face common challenges to POMMs, and in general to purely organic crystals, that is, the difficulty of integrating complexity in crystals. Herein, we propose a simple and sequential strategy for the formation of HOFs with hierarchical superstructures. The strategy is based on controlling the assembly conditions, avoiding the use of any surface functionalization or template, which allows to obtain hierarchical crystalline porous superstructures in an easy manner. As proof of concept, we obtained the first example of core–shell (HOF‐on‐HOF) crystals and HOFs with hierarchical superstructures having superhydrophobicity and trapping abilities for the capture of persistent water contaminants such as oils and microplastics. We expect that this strategy could serve as inspiration for the construction of more intricate multiscale structures that could greatly expand the library of HOF materials.
