Description

Poly(Dibenzo-18-Crown-6) is a polymeric derivative of the classic crown ether, 18-crown-6, characterized by its repeating dibenzo-substituted macrocyclic units. This structure matters for its enhanced stability and ability to selectively complex with alkali metal cations, particularly potassium ions, making it a valuable functional material. It is needed by researchers and manufacturers in advanced material science, analytical chemistry, and specialized separation technologies for developing ion-selective sensors, membranes, and catalysts.

Application

• As a stationary phase or functional component in chromatography for the selective separation of ionic species.
• Incorporation into ion-selective electrodes and chemical sensors for potassium ion detection.
• Use as a phase-transfer catalyst in organic synthesis to facilitate reactions between reagents in immiscible phases.
• Fabrication of functional polymeric membranes for selective ion transport and separation processes.
• Research and development of supramolecular assemblies and host-guest chemistry systems.
• As a model compound in academic and industrial research studying polymer-supported crown ether chemistry.

Quality Control

Our Poly(Dibenzo-18-Crown-6) is produced under controlled conditions to ensure batch-to-batch consistency. Quality is verified through analytical techniques including NMR, FT-IR, and GPC/SEC to confirm structure, functional groups, and molecular weight distribution. A comprehensive Certificate of Analysis (COA) detailing purity, residual solvent levels, and other critical parameters is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a dry environment to prevent absorption of moisture, which may affect performance.
