Abstract Metal-organic frameworks (MOFs) are a class of pervasive nanostructured materials that generate annually an incredible amount of work in different fields, spanning from separation, adsorption, sensing and catalysis to health care and nanomedicine. The combination in their framework of isoreticular ligands and metallic clusters have resulted in a library of confined organic-inorganic hybrid materials with high specific surface area, tunable multimodale porosity and a versatile chemical reactivity. In addition, their processing with synthetic polymers has been recognized as a milestone of their real implementation in everyday life technologies and practices. A step further toward sustainable MOF-based materials has been recently performed by the integration of bio-based precursors in their synthetic procedures either directly as polytopic ligands within the material framework or indirectly as coating reagents or functional surface-modified polymeric materials. This imparted to the resulting MOF-based bio-hybrid materials a set of additional advantages, including hydrophilicity, easy-processing, flexibility, shape-controlled ability, multifunctionality and most importantly, improved biocompatibility. This review article spotlights the fashionable trend in bridging the field of MOF-based materials through the use of bio-based precursors (mainly biopolymers) and discusses how the holistic association of the MOF crystals and the biopolymer matrices resulted in promising materials with prominent properties.

生物聚合物@金属-有机框架混合材料：一项重要调查

摘要 金属有机框架 (MOF) 是一类普遍存在的纳米结构材料，每年在不同领域产生大量令人难以置信的工作，从分离、吸附、传感和催化到医疗保健和纳米医学。等网状配体和金属簇在它们的框架中的组合产生了具有高比表面积、可调多峰孔隙率和通用化学反应性的受限有机-无机杂化材料库。此外，它们对合成聚合物的加工已被认为是它们在日常生活技术和实践中真正实施的里程碑。最近通过将生物基前体整合到它们的合成程序中，或者直接作为材料框架内的多面体配体或间接作为涂层试剂或功能性表面改性聚合物材料，向可持续的基于 MOF 的材料迈进了一步。这赋予了基于 MOF 的生物混合材料一系列额外的优势，包括亲水性、易加工、柔韧性、形状控制能力、多功能性，最重要的是，提高了生物相容性。
