Boradiazaindacene dyads designed as energy transfer casettes can be modified to signal cation concentrations ratiometrically. If the energy transfer efficiency is increased via changing spectral overlap on cation binding, an enhancement of emission signal ratios can be obtained. A larger range of ratios results in highly improved sensitivity to analyte concentrations. We demonstrate this approach in a de novo design of a novel and highly selective ratiometric chemosensor for Hg(II) ions.

GUEST HOST INTERACTIONS IN SODIUM ZEOLITE-Y - STRUCTURAL AND DYNAMIC NA-23 DOUBLE-ROTATION NMR-STUDY OF H2O, PME3, MO(CO)6, AND MO(CO)4(PME3)2 ADSORPTION IN NA56Y
JELINEK, R; Özkar, Saim; PASTORE, HO; MALEK, A; OZIN, GA (American Chemical Society (ACS), 1993-01-01)
Na-23 double-rotation NMR (DOR) provides site-specific structural and dynamical information on guest-host interactions within sodium zeolite Y pores. Quantitative adsorption of H2O, PMe3, and Mo(CO)6 guests affects both the positions and line shapes of the N-23 resonances from specific extraframework Na+ sites. The evolution of the Na-23 DOR spectra with the progressive introduction of guest molecules allows one to probe direct ''solvation'' effects involving the Na+ cations in the larger supercages, as wel...
Iridium(0) nanocluster, acid-assisted catalysis of neat acetone hydrogenation at room temperature: Exceptional activity, catalyst lifetime, and selectivity at complete conversion
Özkar, Saim (American Chemical Society (ACS), 2005-04-06)
Acetone hydrogenation catalysis is important in applications such as heat pumps and fuel cells or in fulfilling the sizable demand for the product of selective acetone hydrogenation, 2-propanol. Reported herein is the discovery of a superior acetone hydrogenation catalyst- superior in terms of activity at low temperature, selectivity at complete conversion, and total catalyst lifetime. The new catalyst system consists of lr(0)(n) nanoclusters plus HCI easily and reproducibly formed from commercially availab...
Cobalt Metallopeptide Electrocatalyst for the Selective Reduction of Nitrite to Ammonium
Guo, Yixing; Stroka, Jesse R.; Kandemir, Banu; Dickerson, Claire E.; Bren, Kara L. (American Chemical Society (ACS), 2018-12-12)
A cobalt-tripeptide complex (CoGGH) is developed as an electrocatalyst for the selective six-electron, eight-proton reduction of nitrite to ammonium in aqueous buffer near neutral pH. The onset potential for nitrite reduction occurs at -0.65 V vs Ag/AgCl (1 M KCl). Controlled potential electrolysis at -0.90 V generates ammonium with a faradaic efficiency of 90 +/- 3% and a turnover number of 3550 +/- 420 over 5.5 h. CoGGH also catalyzes the reduction of the proposed intermediates nitric oxide and hydroxylam...
Nanoparticle Nucleation Is Termolecular in Metal and Involves Hydrogen: Evidence for a Kinetically Effective Nucleus of Three {Ir3H2x center dot P2W15Nb3O62}(6-) in Ir(0)(n) Nanoparticle Formation From [(1,5-COD)Ir-I center dot P2W15Nb3O62](8-) Plus Dihydrogen
Özkar, Saim (American Chemical Society (ACS), 2017-04-19)
The nucleation process yielding Ir(0)(similar to 300) nanoparticles from (Bu4N)(5)Na-3[(1,5-COD)Ir center dot P2W15Nb3O62] (abbreviated hereafter as (COD)Ir center dot POM8-, where POM9- = the polyoxometalate, P2W15Nb3O629-) under H-2 is investigated to learn the true molecularity, and hence the associated kinetically effective nucleus (KEN), for nanoparticle formation for the first time. Recent work with this prototype transition metal nanoparticle formation system (J. Am. Chem. Soc. 2014, 136, 17601-17615...
INTRAZEOLITE METAL-CARBONYL TOPOTAXY - A COMPREHENSIVE STRUCTURAL AND SPECTROSCOPIC STUDY OF INTRAZEOLITE GROUP-VI METAL HEXACARBONYLS AND SUBCARBONYLS
Özkar, Saim; MOLLER, K; BEIN, T (American Chemical Society (ACS), 1990-12-01)
This paper focuses attention on the intrazeolite anchoring, thermal decarbonylation, ligand exchange, and addition chemistry of M(CO)6-M'56Y, where M = Cr, Mo, W; M' = H, Li, Na, K, Rb, Cs. The key points to emerge from this study include the following. (i) M(CO)6-M'56Y samples have the hexacarbonylmetal(O) molecule associated with two alpha-cage extraframework cations (or Bronsted protons), via the oxygen end of two trans bonded carbonyls with a saturation loading of 2M(CO)6/alpha-cage. (ii) M(CO)6-M'56...
