A novel distyryl-substituted boradiazaindacene (bodipy) dye with an emission peak moving hypsochromically from 730 to 680 nm on Zn(II) ion binding seems to be promising as one of the very few water-soluble fluorescent chemosensors emitting in the near IR region.

Electrochromism with selenophene derivatives Aydemir, Kadir; Toppare, Levent Kamil; Department of Chemistry (2008) A novel selenophene-based monomer; 1,4-di(selenophen-2-yl) benzene (DSB), synthesized via Stille coupling reaction of 1,4 dibromobenzene and tributyl (2-selenophenyl) stannane and corresponding conducting homopolymer (Poly (DSB)) was electrochemically synthesized in the presence of tetrabutylammoniumhexafluorophosphate (TBAPF6) as the supporting electrolyte in dichloromethane. The resulting conducting polymer was characterized by Cyclic Voltammetry (CV), Fourier Transform Infra Red Spectrometry (FTIR) and U...
Remarkable phosphodiester hydrolysis activity of a novel Ce-IV complex in neutral aqueous solutions Baykal, U; Akkaya, Mahinur; Akkaya, EU (1999-09-08) A novel Ce-IV-complex of 1,4,7-tris(carbamoylmethyl)-1,4,7-triazacyclononane has been synthesized. The complex is both stable in aqueous solutions at neutral pH and very efficient in promoting the hydrolysis of a phosphodiester model compound and yeast tRNA(phe). The RNA model compound, 2-hydroxypropyl-p-nitrophenylphosphate hydrolysis is accelerated 7400-fold at pH 7.5, as a result of an unprecedented hydrolytic activity.
Selective recognition of anionic cell membranes using targeted liposomes coated with zinc(II)-bis(dipicolylamine) affinity units Türkyılmaz, Serhan; Palumbo, Rachael; Smith, Bradley D. (Royal Society of Chemistry (RSC), 2014-08-14) Zinc(II)-bis(dipicolylamine) (Zn(2)BDPA) coated liposomes are shown to have high recognition selectivity towards vesicle and cell membranes with anionic surfaces. Robust synthetic methods were developed to produce Zn(2)BDPA-PEG-lipid conjugates with varying PEG linker chain length. One conjugate (Zn(2)BDPA-PEG(2000)-DSPE) was used in liposome formulations doped with the Lipophilic near-infrared fluorophore DiR. Fluorescence cell microscopy studies demonstrated that the multivalent Liposomes selectively and ...
A Low Band Gap Benzimidazole Derivative and Its Copolymer with 3,4-Ethylenedioxythiophene for Electrochemical Studies Soylemez, Saniye; Hacioglu, Serife O.; Uzun, Sema Demirci; Toppare, Levent Kamil (The Electrochemical Society, 2014-11-7) A novel monomer; 2-(3-nitrophenyl)-4,7-di(thiophen-2-yl)-1H-benzo[d]imidazole) (BIMN) was used for electrochemical copolymerization with 3,4-ethylenedioxythiophene (EDOT). Polymerization was achieved in acetonitrile (ACN)/dichloromethane (DCM) (1:1, 1:3 and 1:5, molar ratios) solution containing sodium perchlorate (NaClO4) and lithium perchlorate (LiClO4) mixture as the supporting electrolyte on an ITO electrode. The chemical structures of monomer and copolymers were characterized by nuclear magnetic resona...
Synthesis of bifunctional 2-aminodmap/prolinamide organocatalysts and their use in asymmetric michael reaction to afford warfarin Akkoca, Hasan Ufuk; Tanyeli, Cihangir; Department of Chemistry (2012) In the first part of this thesis, the construction of the novel bifunctional proline-(1R,2R)-2-aminoDMAP organocatalyst backbone is described. Target compound has both Lewis base and Brønsted acid catalaphoric sites. The Lewis base site is synthesized via selective mono-N-pyridilization of trans-(1R,2R)-cyclohexane-1,2-diamine by Cu catalysis and Brønsted acid site is subsequently introduced by anchoring L-proline unit. In the second part, catalytic activities of organocatalysts are tested in asymmetric Mic...
