Description

Tetra(Diphenoxyphosphoryl)!Tetra-Methylcalix[4!Resorcinolarene, 98 is a highly functionalized calixarene derivative, specifically a phosphorylated calix[4]resorcinarene, designed for advanced supramolecular and coordination chemistry applications. This compound matters for its exceptional ability to act as a sophisticated ligand or host molecule, selectively binding to specific metal ions or organic guests due to its pre-organized cavity and multiple donor sites. It is needed by researchers and developers in pharmaceutical intermediates, catalyst design, sensor technology, and advanced material science where precise molecular recognition is critical.

Application

• Supramolecular Host-Guest Chemistry: As a building block for creating complex molecular capsules and receptors.
• Catalyst Ligand: For designing transition metal catalysts used in asymmetric synthesis and polymerization.
• Ion-Selective Sensors & Extraction: Development of selective electrodes or solid-phase extractants for metal ions.
• Pharmaceutical Intermediate: In the synthesis of novel drug candidates requiring complex, functionalized macrocyclic structures.
• Advanced Material Precursor: For creating functionalized surfaces, polymers, or porous frameworks with tailored properties.
• Analytical Chemistry: As a chiral selector or stationary phase modifier in chromatography.
