Single oxides of Ti and Zr incorporated SBA-15 were prepared and characterized by N-2 adsorption, NMR, and XPS techniques. Si-29 MAS NMR results suggest the formation of Si-O-X linkages (X: Ti or Zr) by an increase in the ratio of Q(3)/Q(4) in the presence of Ti or Zr. XPS analysis of Ti-SBA-15 catalysts indicate the presence of Ti-O-Si bonds in addition to Ti-O-Ti and Si-O-Si bonds, supporting the NMR evidence.

Synthesis and properties of a novel redox driven chemiluminescent material built on a terthienyl system Atilgan, Nurdan; Algi, Fatih; Önal, Ahmet Muhtar; CİHANER, ATİLLA (Elsevier BV, 2009-07-18) A novel redox driven chemiluminescent material built on a terthienyl system, namely 5,7-di-ethylenedioxythiophen-2-yl-2,3-dihydro-thieno[3,4-d]pyridazine-1,4-dione (ETE-Lum), which is soluble in both organic media and basic aqueous solution was synthesized and characterized. Furthermore, its polymer, PETE-Lum, which is one of the most rare examples of chemiluminescent polymeric materials bearing a pyridazine unit, was obtained successfully by electrochemical means. Both of the materials give chemiluminescen...
Synthesis and characterization of a new soluble conducting polymer and its electrochromic device Varis, Serhat; Ak, Metin; Tanyeli, Cihangir; Akhmedov, Idris Mecidoglu; Toppare, Levent Kamil (Elsevier BV, 2006-12-01) A mixture of isomers 2,5-di(4-methyl-thiophen-2-yl)-1-(4-nitrophenyl)-1H-pyrrole, 2-(4-methyl-thiophen-2-yl)-5-(3-methyl-thiophen-2-yl)1-(4-nitrophenyl)-1H-pyrrole and 2,5-di(3-methyl-thiophen-2-yl)-1-(4-nitrophenyl)-1H-pyrrole (Me-SNS(NO2)) were synthesized. Resulting monomers were polymerized chemically, producing soluble polymers in common organic solvents. The average molecular weight has been determined by gel permeation chromatography (GPC) as Mn = 5.6 x 10(3) for the chemically synthesized polymer. T...
Synthesis, characterization, and polymerization of polyether bridged thiophene and aniline derivatives Tirkeş, Seha; Önal, Ahmet Muhtar; Department of Polymer Science and Technology (2008) New compounds consisting of 3-thienyl and aniline units linked by polyether bridges have been synthesized and their electrochemical polymerization was performed via constant potential electrolysis and cyclic voltammetry. In the case of 3-thienyl derivatives two compounds, 1,12-di-3-thienyl-2,5,8,11-tetraoxadodecane (MI) and 1,15-di-3-thienyl-2,5,8,11,14-pentaoxapentadecane (MII) were synthesized utilizing literature methods and their corresponding polymers, poly(I) and poly(II) were prepared in an electroly...
Synthesis of novel norephedrine-based chiral ligands with multiple stereogenic centers and their application in enantioselective addition of diethylzinc to aldehyde and chalcone Unaleroglu, C; Aydin, AE; Demir, Ayhan Sıtkı (Elsevier BV, 2006-03-06) Novel norephedrine-based chiral ligands with multiple stereogenic centers were conveniently prepared from norephedrine and N-substituted pyrrole. These novel chiral ligands were used to catalyze the enantioselective addition of diethylzinc to aldehydes and to chalcone in high yields and with good to high enantioselectivities. The absolute configuration of products was found to be affected by the stereogenic centers on the norephedrine part of the novel chiral ligands.
Synthesis and characterization of a new soluble conducting polymer and its electrochromic devices Sahin, Elif; Sahmetlioglu, Ertugrul; Akhmedov, Idris M.; Tanyeli, Cihangir; Toppare, Levent Kamil (Elsevier BV, 2006-10-01) A new polythiophene derivative was synthesized by both chemical and electrochemical oxidative polymerization of 1-(perfluorophenyl)-2,5-di(2-thienyl)-1H-pyrrole (FPTPy). The structures of both the monomer and the soluble polymer were elucidated by nuclear magnetic resonance (H-1-NMR) and fourier transform infrared (FTIR). Polymer of FPTPy was also synthesized via potentiostatic electrochemical polymerization in acetonitrile (AN)/NaClO4/LiClO4 (0.1 M:0.1 M) Solvent-electrolyte couple. Characterizations of th...
