Synthesis and Design of Functional Covalent Organic Frameworks
Abstract:

Covalent organic frameworks (COFs) are a class of advanced materials that are composed of light elements (C, H, O, N, and B) linked via strong covalent bonds. COFs are generally constructed by using reversible bond forming reactions to yield crystalline materials with high surface areas, low densities, and high thermal stabilities. These  features make COFs useful forcarbon capture, gas storage, and sensory applications.  This lecture willdiscuss employing a bottom-up approach to create novel functional COFsthat can bind small metal cations (e.g., Li, Ca, etc.), and some low-oxidation
state transition metals (e.g., Ag(I), Co(II), Fe(II), etc.). The prospects of utilizing these metal-doped COFs for applications related to carbon capture, hydrogen gas storage, and membrane separations will be highlighted.

ENCOMM Seminar – John O. Huston

Wednesday, August 31

4:15-5:15 pm, 1080 Smith Seminar Room, Physics Research Building

 

Angel Investor, Founder and former Fund Manager of the Ohio TechAngel Funds (OTAF) and Angel Capital Association (ACA) Chair Emeritus and Ex Officio

 

During his 30-year commercial banking career, John’s positions at banks in five states ranged from Chief Lending Officer to Chief Credit Officer to CEO. After retiring from banking in 2000 he commenced his business angel activities, forming USPrivateCompanies, LLC which has provided capital to 50+ Ohio entrepreneurs. He currently is a Director of three portfolio companies.

 

John has served on the Ohio Venture Capital Authority and the Ohio Third Frontier Advisory Board, having been appointed by Governors of both political parties. He is a Founding Director of VentureOhio, the trade association providing the unified voice for Ohio’s innovation community.

 

When John launched the first Ohio TechAngel Fund (OTAF) in 2004 with 50 investors, the group became a founding member of the Angel Capital Association (ACA). Now with five funds and 300+ members, OTAF is one of the world’s largest angel groups. John is also a member of the North Coast Angel Funds (Cleveland), and the East Central Ohio TechAngel Funds (Athens). He is a founding member of Columbus-based X-Squared Angels, a group which invests nationwide in start-up ventures with diverse management teams.

 

Internationally, John is well known as the past Chairman of both the ACA and the Angel Resource Institute (ARI). At their March 2012 Summit these organizations awarded John their highest accolade, the Hans Severiens Award for angel leadership.

“Sustainable Material Design and
Synthesis: Creating Tools for
Selective Reactions”
Rapid consumption of energy and material resources demands that we identify new and more sustainable manufacturing processes. Indeed, increased focus is placed on sustainable manufacturing with new metrics providing insights on how processes can be improved
. The key challenge is increasing reaction selectivity for producing materials and converting resources. Great opportunity exists to discover fundamentally more sustainable processes and save the planet through creating more selective processes. Our group uses a combination of tools from synthetic chemistry and chemical engineering to overcome these challenges. We will examine these new tools that are group is creating to increase the selective catalytic conversion of biomass to materials and chemicals to fine chemicals. We will also demonstrate a new method to assemble zeolite imidazolate frameworks (ZIFs) – a promising material for low energy membrane separations – in a sustainable manner. Overall, these new tools will help improve manufacturing sustainability through reducing energy and material consumption.

ENCOMM seminar – Joel Miller (University of Utah) Organic-based Magnets: New Chemistry, New Physics and New Materials for This Millennium

Wednesday, April 26, 2017 – 4:15pm to 5:15pm
4138 Physics Research Building

Organic-based materials exhibiting the technologically important property of bulk magnetism have been pioneered in our laboratory and studied in collaboration with many research groups worldwide.  These magnets are prepared via conventional organic synthetic chemistry methodologies, but unlike classical inorganic-based magnets do not require high-temperature metallurgical processing.  Furthermore, these magnets are frequently soluble in conventional organic solvents and have saturation magnetizations more than twice that of iron metal on a mole basis, as well as in some cases coercive fields exceeding that of all commercial magnets (e.g., Co5Sm).  Also several magnets with critical temperatures (Tc) exceeding room temperature have been prepared.  In addition to an overview of magnetic behavior, numerous examples of structurally characterized magnets made from molecules will be presented. Four examples magnetically order above room temperature and as high at 127 oC.  These will include [MIII(C5Me5)2][A], [MnIII(porphyrin)][A] (A = cyanocarbon etc. electron acceptors) as well as M[TCNE]x (TCNE = tetracyanoethylene), which for M = V is a room temperature magnet that can be fabricated as a thin film magnet via Chemical Vapor Deposition (CVD) techniques.  A newer class of magnets of [Ru2(O2CR)4]3[M(CN)6] (M = Cr, Fe; R = Me, t-Bu) composition will also discussed.  For R = Me an interpenetrating, cubic (3-D) lattice forms and the magnet exhibits anomalous hysteresis, saturation magnetization, out-of-phase, c“(T), AC susceptibility, and zero field cooled-field cooled temperature-dependent magnetization data.  This is in contrast to R = t-Bu, which forms a layered (2-D) lattice.  Additionally, new magnets possessing the nominal Prussian blue composition, M'[M(CN)6]x and (Cation)yM'[M(CN)6], but not their structure, will be described.  This forms a series of cation-adaptive structures with [NEt4]2Mn3(CN)8, [NEt4]Mn3(CN)7, [NMeEt3]2Mn5(CN)12 and [NMe4]3Mn5(CN)13 stoichiometries that order as antiferromagnets or ferrimagnets.   Finally, Li[TCNE]  magnetically orders as a weak ferromagnet (= canted antiferromagnet) below 21.0 K.  The structure, determined ab initio from synchrotron powder X-ray diffraction data, consists of a planar µ4-[TCNE]•- bound to four tetrahedral Li+ ions with two interpenetrating diamondoid sublattices, with closest inter-lattice separations of 3.43 and 3.48 Å.  At 5 K this magnetic state is characterized by a coercivity of ~30 Oe, 10 emuOe/mol remnant magnetization, and a canting angle of 0.5o.  The structure, DC magnetization at ambient and applied pressure, as well as the AC susceptibility at ambient pressure in addition to the computational analysis of the magnetic couplings will be presented.  New physics observed from examples of organic-based magnet will be discussed.
