Donor-acceptor diblock copolymers, composed of regioregular Poly(3-hexylthiophene) (rrP3HT) as the electron donor block and poly(perylene diimide acrylate) (PPDA) as the electron acceptor block, were prepared and used to fabricate a solar cell. Vinyl-terminated rrP3HT was synthesized by Grignard metathesis polymerization and converted to an alkoxyamine macroinitiator. This polythiophene macroinitiator was used in controlled free radical polymerization of a perylene diimide-containing acrylate. The targeted donor-acceptor diblock copolymers were prepared with low-to-moderate polydispersity indices ( 1.2-1.4) and molecular weights sufficiently high for producing films by spin-coating. These copolymers showed efficient photoluminescence quenching in the solid state, indicative of charge separation, and were Used to produce a solar cell with power conversion efficiency of 0.49%.

Thermal analysis of a new thiophene derivative and its copolymer Aslan, E.; Toppare, Levent Kamil; Hacaloğlu, Jale (2008-06-01) Thermal characteristics of a new thiophene derivative, 2-(thiophen-3-yl-)ethyl octanoate (OTE), its homopolymer (POTE), and copolymer with thiophene P(OTE-co-Th) were investigated via pyrolysis mass spectrometry. Thermal degradation of the copolymer started by lose of side chains and thiophene involving products evolved almost in the same temperature range where PTh degradation was detected, at slightly higher temperatures than PTh backbone decomposed during the pyrolysis of POTE. The extent of doping and n...
Production of core-shell type conducting FTO/TiO2 photoanode for dye sensitized solar cells Icli, Kerem Cagatay; Yavuz, Halil Ibrahim; Özenbaş, Ahmet Macit (2014-02-01) Core-shell type photoanode composed of electrically conducting fluorine doped tin dioxide (FTO) matrix and TiO2 shell layer was prepared and applied in dye sensitized solar cells. Effects of fluorine doping on tin dioxide based cells and precursor material on shell layer were investigated. Fluorine doped tin dioxide nanoparticles were synthesized under hydrothermal conditions and resistivity value down to 17 Omega cm was achieved. Cells constructed from FTO nanoparticles show enhanced performance compared t...
Poly(methyl methacrylate) organoclay composites; interactions of organic modifier with the polymer effecting thermal degradation behavior Ozdemir, Esra; Hacaloğlu, Jale (2017-10-01) In this work, poly(methyl methacrylate), PMMA, and its composites involving montmorillonites modified with different quaternary ammonium salts were prepared and characterized by X-ray Diffraction, XRD, Transmission Electron Microscopy, TEM, Thermogravimetry, TGA and direct pyrolysis mass spectrometry, DPMS. Increase in the interlayer spacing of the silicate layers compared to the corresponding organically modified clay was detected in X-ray diffractograms for all the PMMA composites in accordance with TEM r...
Synthesis, characterization and electrochromic properties of copolymer of 3-{[4-(thien-3-yl-methoxy)phenoxy]methyl} thiophene with thiophene Erden, Ayca; Sahin, Elif; Gullu, Mustafa; Toppare, Levent Kamil (Elsevier BV, 2006-08-01) (3- {[4-(Thien-3-yl-methoxy)phenoxy]methyl} thiophene) (TMPMT) was synthesized via the reaction of 3-bromomethyl-thiophene with hydroquinone and characterized by nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FTIR). Electrochemical copolymerization of TMPMT with thiophene in acetonitrile/boron trifluoride diethyl etherate (AN/BFEE) solvent mixture was achieved using tetrabutylammonium tetrafluoroborate (TBAFB) as the supporting electrolyte. Resulting copolymer was characterize...
Mass and charge distributions in the very asymmetric mass region of the neutron induced fission of Np-238 Tsekhanovich, I; Denschlag, HO; Davi, M; Buyukmumcu, Z; Gonnenwein, F; Oberstedt, S; Faust, HR (2001-06-04) The mass-separator Lohengrin was used to measure the yields of the light fission products with A = 74-85 and their nuclear charge and kinetic energy distributions from the odd-Z compound nucleus Np-239* formed by double capture of thermal neutrons. The mass yield distribution reveals an influence of the fragment shell with N = 50 affecting also the nuclear charge and kinetic energy distributions. An odd-even effect for protons is found in the very asymmetric mass division, increasing from 4% to 35% with inc...
