The synthesis of two novel tetrakis(salicylaldehydes) based on a rigid tetraphenylmethane core is presented. These salicylaldehydes were used as precursors for the construction of three-dimensional multimetallic salphens, as exemplified by the synthesis of rigid and shape-persistent tetranuclearzinc–, nickel– and palladium–salphens with defined geometries and distances between the metal sites.

Produce the target substance, or a polynuclear poly(formylphenol) expressed by General Formula (2), in an industrial setting with ease and at high purity by causing a polynuclear poly(hydroxymethylphenol) or polynuclear poly(alkoxymethylphenol) to react with hexamethylene tetramine in the presence of an acid and then hydrolyzing the obtained reaction product.
The development of three-dimensional (3D) functionalized covalent-organic frameworks (COFs) is of critical importance for expanding their potential applications. However, the introduction of functional groups in 3D COFs remains largely unexplored. Herein, we report the first example of 3D Salphen-based COFs (3D-Salphen-COFs) and their metal-containing counterparts (3D-M-Salphen-COFs). These Salphen-based
三维 (3D) 功能化共价有机框架 (COF) 的开发对于扩展其潜在应用至关重要。然而,在 3D COF 中引入官能团在很大程度上仍未得到探索。在此,我们报告了基于 3D Salphen 的 COF(3D-Salphen-COF)及其含金属对应物(3D-M-Salphen-COF)的第一个示例。除了优异的化学稳定性外,这些基于 Salphen 的 COF 还具有高结晶度和比表面积。此外,Cu(II)-Salphen COF 在去除超氧自由基方面表现出很高的活性。该研究不仅提供了构建 3D 功能化 COF 的新途径,而且促进了它们在生物学和医学中的应用。

The one-pot three component synthesis of metal containing microporous organic polymers with high BET surface areas is presented. The metal salphen units were built during the formation of the porous polymers. Selective gas adsorption depending on the metal ions is discussed.
