Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Supramolecular gels based on lanthanide salts lack ideal magnetic and structural properties for integration into information storage devices, and existing supramolecular nanotubes of single-chain magnets are difficult to deposit on surfaces due to their crystalline form.
Innovation Solution
Development of supramolecular nanotubes comprising single-chain magnets with linear coordination polymers and aliphatic carbon chains, allowing for the formation of metallogels that can be easily deposited on solid substrates, utilizing transition metals like terbium and nitronyl-nitroxide radical ligands to achieve suitable magnetic relaxation and structural properties for information storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If supramolecular nanotubes of single-chain magnets are prepared in crystalline form, then they possess ideal magnetic hysteresis curves for information storage, but they become difficult or impossible to deposit on surfaces
Solution Approach 1:
The patent changes the physical state parameter of the supramolecular nanotubes from crystalline to gel form. This parameter change enables the material to be deposited on surfaces while maintaining the magnetic properties through the preservation of the nanotube structure in the gel phase
Solution Approach 2:
The patent creates a composite material system combining supramolecular nanotubes with gel matrix. The nanotubes provide the magnetic hysteresis properties while the gel matrix provides the deposition capability, resolving the contradiction between magnetic quality and manufacturability
2Illumination intensity
If lanthanide salts are used to manufacture supramolecular gels, then luminescent features are obtained, but ideal magnetic properties for information storage are not achieved
Solution Approach 1:
The patent extracts the magnetic functionality from the lanthanide-based system by incorporating single-chain magnets as distinct supramolecular assemblies within the gel. This separation allows the gel matrix to provide structural properties while the SCM nanotubes provide ideal magnetic hysteresis curves
Solution Approach 2:
The patent creates a composite system where the gel matrix (which may contain luminescent lanthanide components) is combined with supramolecular nanotubes of single-chain magnets. This composite structure allows simultaneous achievement of luminescent features and ideal magnetic properties for information storage applications
