In this work, we report the first metal-organic framework (MOF) fabric composite capable of both rapid catalytic hydrolysis and photo-oxidation of multiple chemical warfare agents (GD and HD) and their simulants. A simple template-free low-temperature synthesis yields new zirconium-porphyrin based nano-crystalline PCN-222 MOF-fabrics with adjustable MOF loading and robust mechanical adhesion on low-cost nonwoven polypropylene fibers. Importantly, we report the discovery of visible photo-activation of GD hydrolysis by a MOF-fabric, which is ascribed to oxidation at the active metal node site, significantly increasing the rate over that observed without illumination. Moreover, because the active MOF catalysts are uniformly displayed on the MOF-textile, the composite geometry enhances the kinetics of active agent photo-degradation relative to the same mass of MOF in common powder form. These results provide important new insights into the design of future materials and chemical systems to protect military, first-responders, and civilians upon exposure to complex chemical toxins.}, number={4}, journal={CHEMISTRY-A EUROPEAN JOURNAL}, publisher={Wiley}, author={Barton, Heather F. and Jamir, Jovenal D. and Davis, Alexandra K. and Peterson, Gregory W. and Parsons, Gregory N.}, year={2021}, month={Jan}, pages={1465–1472} }

Until recently, vapor-phase synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT) has relied on solid reactants which require relatively high temperatures and complex dosing schemes for sequential layer-by-layer processes. This work introduces a facile and high-performing layer-by-layer oxidative molecular layer deposition (oMLD) scheme using the volatile liquid oxidant antimony(V) chloride (SbCl5) to deposit PEDOT thin films. Effects of reactor parameters on PEDOT film characteristics are described, and the necessary foundation for future studies aiming to understand the nucleation and growth of layer-by-layer oMLD PEDOT is detailed.}, number={3}, journal={JOURNAL OF VACUUM SCIENCE & TECHNOLOGY A}, publisher={American Vacuum Society}, author={Volk, Amanda A. and Kim, Jung-Sik and Jamir, Jovenal and Dickey, Elizabeth C. and Parsons, Gregory N.}, year={2021}, month={May} }

This article reports for the first time the exceptional photocatalytic reactivity of Al-PMOF (Al-porphyrin-based MOF), composed of an earth-abundant metal-containing Al(OH)O4 cluster bridged by H2TCPP (5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin) chromophores, against the toxic sulfur mustard simulant 2-chloroethyl ethyl sulfide (CEES) under visible-light irradiation. Furthermore, Al-PMOF is strongly immobilized into polymeric fibers via well-controlled Al2O3 solid film conversion using dimethylformamide/water cosolvent. The approach enables a secure integration of conformal Al-PMOF films onto polymer fibers at a relatively low synthesis temperature (120°C). In addition, on a per-unit mass of MOF basis, the surface-bound Al-PMOF films enable extremely rapid CEES detoxification turnover frequency, up to 170 molCEESmolchromophore−1min−1, more than 10-fold faster than the best MOF powders and 2-fold better than MOF films reported to date.}, number={2}, journal={MATTER}, author={Lee, Dennis T. and Jamir, Jovenal D. and Peterson, Gregory W. and Parsons, Gregory N.}, year={2020}, month={Feb}, pages={404–415} }

Herein, water-stable, polymer fiber surface-oriented M-TCPP [M = Cu, Zn, and Co; H2 TCPP = 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin] 2D MOF crystals are fabricated using a facile hydroxy double salt (HDS) solid-source conversion strategy. For the first time, Cu-TCPP is formed from a solid source and confirmed to be highly adsorptive for NH3 and 2-chloroethyl ethyl sulfide (CEES), a blistering agent simulant, in humid (80% relative humidity (RH)) conditions. Moreover, the solid HDS source is found as a unique new approach to control MOF thin-film crystal orientation, thereby facilitating radially arranged MOF crystals on fibers. On a per unit mass of MOF basis in humid conditions, the MOF/fiber composite enhances NH3 adsorptive capacity by a factor of 3 compared to conventionally prepared MOF powders. The synthesis route extends to other MOF/fiber composite systems, therefore providing a new route for chemically protective materials.}, number={10}, journal={SMALL}, publisher={Wiley}, author={Lee, Dennis T. and Jamir, Jovenal D. and Peterson, Gregory W. and Parsons, Gregory N.}, year={2019}, month={Mar} }
