A pair of novel dipicolylamine ligands bearing isothiocyanate groups were used as conjugation reagents to prepare multivalent molecules with anionic recognition capability. The isothiocyanates were reacted with two classes of dendritic scaffolds bearing primary amines, squaraine rotaxanes, and PAMAM dendrimers, and the products were converted into water soluble zinc(II) coordination complexes. The multivalent squaraine rotaxanes exhibit high fluorescence quantum yields in water and are very well suited for biological imaging applications.

Electrochemical study of tricarbonyl(eta(6)-cyclooctatetraene)metal(0) complexes of the group 6 elements Yilmaz, GA; Önal, Ahmet Muhtar; Özkar, Saim (1998-08-01) Tricarbonyl(eta(6)-cyclooctatetraene)metal(0) complexes of the group 6 elements were prepared by using the procedures described in the literature with some minor modifications and identified by IR and NMR spectroscopy. Their electrochemical behavior was studied by using cyclic voltammetry in dichloromethane solution containing 0.1 M tetrabutylammonium tetrafluoroborate as supporting electrolyte. Their oxidation and reduction potentials were measured and discussed in terms of the frontier energy levels in co...
Novel studies on the chemoenzymatic synthesis of polychlorinated bicyclic systems and the synthesis of C2 and C3 symmetric chiral ligands Türkmen, Yunus Emre; Tanyeli, Cihangir; Department of Chemistry (2006) Optically active polychlorinated bicyclic systems are important starting materials for the synthesis of complex target molecules. In the first part of the study, the syntheses of several racemic and meso hexachloronorbornene derivatives were executed successfully, starting from hexachlorocyclopentadiene. The enantio-enriched acetoxymethyl derivative (-)-2 and the hemiester (-)-6 were synthesized in high e.e. values by using several hydrolase type enzymes. The absolute configuration of (-)-2 was determined b...
The effect of the different donor units on fluorescent conjugated polymers containing 2,1,3-benzooxadiazole as the acceptor unit Goker, Seza; Hizalan, Gonul; Ileri, Merve; Hacioglu, Serife O.; Toppare, Levent Kamil (2015-08-15) A series of monomers were synthesized via Stille coupling to obtain low-band gap conjugated polymers namely poly(5,6-bis(octyloxy)-4,7-di(thieno[3,2-b]thiophen-2-yl)benzo[c][1,2,5]oxadiazole (PTTBO)), poly(5,6-bis(octyloxy)-4,7-di(selenophen-2-yl)benzo[c][1,2,5]oxadiazole (PSBO)) and poly(5,6-bis(octyloxy)-4,7-di(furan-2-yl)benzo[c][1,2,5]oxadiazole (PFBO)) which comprise electron-rich thieno[3,2b]thiophene (TT), selenophene and furan, as the donor units in conjugation with electron-deficient 2,1,3-benzooxa...
Synthesis, characterization and electrical properties of diazophenylene and diazodiphenylene bridged co, ni, cu, ce, and er phthalocyanine polymers Alkan, Cemil; Alkan, Cemil; Department of Polymer Science and Technology (2004) In this research, diazophenylene and diazodiphenylene bridged metal-phthalocyanine polymers were produced from diazonium salt of diaminophenylene/bensidin and pre-synthesized tetraamino metal phthalocyanines. Tetraamino metal phthalocyanine complexes of Co, Ni, Cu, Ce, and Er were obtained by reducing tetranitro metal phthalocyanine complexes synthesized from 3-nitrophthalic anhydride, urea, metal salt, and ammonium molybdate catalyst. Complexes and polymers were characterized by Fourier Transform Infrared ...
Synthesis and characterization of conjugated polymers with polyhedral oligomeric silsesquioxane pendant groups Ertan, Salih; Kaynak, Cevdet; Cihaner, Atilla; Department of Polymer Science and Technology (2017) In this thesis, a series of monomers covalently bonded to polyhedral oligomeric silsesquioxane (POSS) pendant group was designed and synthesized. POSS group is a hybrid organic-inorganic nanostructure with 1 to 3 nm diameter. POSS which has a cage structure is mainly composed of silicon (Si) (at vertices) and oxygen (O) (in the middle of the edge). POSS nanostructure can be modified through the vertices with organic functional groups. POSS groups provide different properties, such as thermal robustness, mec...
