Description

Abstract: Improvised chemical threats based on toxic industrial chemicals pose a significant threat to both soldier and civilian populations. This proposal aims to
develop multifunctional materials that could be capable of simultaneously
displaying chemical-agent-selective signaling, capture, and destruction of toxic
industrial chemicals. Designed metal–organic framework materials (MOFs) have
the potential to be multifunctional. To fully realize this potential, we will take
advantage of several recent advances in metal–organic framework chemistry,
including:
(a) The ability to grow functional MOFs via Layer-by-Layer (L-B-L)
(b) Systematically tailoring mesoporous MOFs via Atomic-Layer Deposition
(ALD)
(b) Systematically functionalization of mesoporous MOFs via Solvent Assisted
Linker Exchange (SALE)
Proposed Statement of Work:
1. Functional L-B-L Assembled Systems
• Stepwise growth of single-, dual- and three-component MOF-based
materials
• Incorporation of metal-oxide nanoparticles within L-B-L encapsulants
• Synthesis of multifunctional materials capable of signaling, capture, and
destruction
• Large-area L-B-L syntheses
• Conformal L-B-L growth on non-flat surfaces
2. Enabling Multifunctional Materials for Force Protection with MOF Platforms
and ALD
• Synthesis of zirconium hydroxide clusters within NU-1000 for SO2 and
cyanogen chloride capture and transformation
• Synthesis of copper oxide clusters within NU-1000 for the capture of
ammonia
• Synthesis of titanium dioxide clusters within NU-1000 as photochemical
generators of hydroxyl radicals for chemical agent destruction.
3. Enabling Multifunctional Materials for Force Protections in MOF Platforms
by SALE
• Incorporation of perfluroalkanes within NU-1000 for enhanced ammonia
uptake
• Incorporation of other organic functionalities within NU-1000 capable of
destruction (e.g., oligomeric phenol incorporation for redox-reactive
capture of chlorine) and modification (e.g., chel
