ABSTRACT

Pillar-layered metal-organic frameworks (PL-MOFs) are advanced crystalline porous substances built using metal ions, oxygen- and nitrogen-donor linkers. The pillar-layered strategy emerged as a very effective way to incorporate the Schiff base functionalities into pore cages of MOFs by using N-donor Schiff base pillar ligands. The Schiff base functionalities provide active sites for enhanced performance in sensing, catalysis, adsorption, extraction, and gas separation areas. Although the PL-MOFs have gained remarkable advances in the last few decades, Schiff base PL-MOFs have been reviewed to a lesser extent up to this point. In this way, a review summing up their performance is profoundly expected. This review covered the recent developments connected with Schiff base PL-MOFs, including synthesis and applicability in various potential fields. It also included the challenges and forthcoming pathways for fulfilling the research and development needs of Schiff base PL-MOFs.

摘要

柱状层状金属有机框架（PL-MOF）是使用金属离子、氧供体和氮供体连接体构建的先进结晶多孔物质。柱分层策略是一种非常有效的方法，通过使用 N 供体席夫碱柱配体将席夫碱功能整合到 MOF 的孔笼中。席夫碱功能提供活性位点，以增强传感、催化、吸附、萃取和气体分离领域的性能。尽管 PL-MOF 在过去几十年中取得了显着的进步，但迄今为止对席夫碱 PL-MOF 的审查程度较小。这样一来，对他们的表现进行总结的回顾就令人深感期待。本综述涵盖了席夫碱 PL-MOF 的最新进展，包括合成和在各个潜在领域的适用性。
