Electronic spectral behavior of polyvinylpyrrolidone solutions in various media has been determined by UV-VIS spectrophotometry. A theoretical approach has been developed to explain the experimentally observed concentration dependent spectral behavior of polyvinyl pyrrolidone in aqueous and nonaqueous solvents. Increase in the concentration of the polymer or the addition of guanidine salts caused bathochromic shift. A similar concentration effect has been observed in nonaqueous media in the absence of guanidine salts.

Optical and vibrational properties of nickel integrated germanium Zintl ion clusters Ogun, Esra; Esentürk, Okan; Nalbant Esentürk, Emren (Elsevier BV, 2019-05-01) Vibrational and optical properties of Ni-Ge clusters ([Ni2Ge9(PPh3)](2-), [Ni6Ge13(CO)(5)](4-)) have been investigated via UV-Vis, FTIR, and Fluorescence spectroscopies. Moreover, frequency and time-dependent (TD) electronic transition calculations have been performed to better characterize experimental findings, due to the scarcity of vibrational and optical spectroscopic studies on these type of clusters in the literature. UV-Vis spectroscopic analyses demonstrate a broad absorption band, with a maximum a...
Electropolymerization of a New 4-(2,5-Di-2-thiophen-2-yl-pyrrol-1-yl)-Tetra Substituted Nickel Phthalocyanine Derivative Yavuz, Arzu; Carbas, Buket Bezgin; Aras, Leyla; Önal, Ahmet Muhtar (Wiley, 2011-10-15) A new tetrakis 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl) substituted nickel phthalocyanine (NiPc-SNS) was synthesized and characterized by elemental analysis, Fourier Transform Infrared (FT-IR), and UV-vis spectroscopies. The electrochemical polymerization of this newly synthesized NiPc-SNS was performed in dichloromethane (DCM)/tetrabutylammonium perchlorate (TBAP) solvent/electrolyte couple. An insoluble film was deposited on the electrode surface, both during repetitive cycling and constant potential electr...
Differential charging in SiO2/Si system as determined by XPS Karadas, F; Ertaş, Gülay; Suzer, S (American Chemical Society (ACS), 2004-01-29) The Si2p binding and the Si-KLL kinetic energy difference between the SiO2 layer and Si substrate is shown to be influenced by application of external voltage bias to the sample holder due to the differential charging as was already reported earlier (Ulgut, B.; Suzer, S. J. Phys. Chem. B 2003, 107, 2939). The cause of this bias induced (physical)-shift is now proven to be mostly due to partial neutralization by the stray electrons within the vacuum system by (i) introducing additional stray electrons via a ...
Electronic absorption and MCD spectra for octacyanometallate complexes M(CN)(8)(n-), M = Mo(IV), W(IV), n=4 and Mo(V), W(V), n=3 Isci, H; Mason, WR (Elsevier BV, 2004-11-15) Electronic absorption and 8.0 T magnetic circular dichroism (MCD) spectra are reported for M(CN)(8)(4-), M = Mo(IV) and W(IV), in aqueous solution and M(CN)(8)(3-), M = Mo(V) and W(V), in acetonitrile solutions. In addition some absorption and MCD spectra are reported for the M(CN), 3- ions embedded in thin poly methyl methacrylate (PMMA) plastic films at temperatures from 295 to 10 K. The temperature dependence of the MCD spectra confirms the presence of C terms. The solution and PMMA spectra for the both ...
Spectroelectrochemical and Photovoltaic Characterization of a Solution-Processable n-and-p Type Dopable Pyrrole-Bearing Conjugated Polymer Baran, Derya; Balan, Abidin; Esteban, Beatriz-Meana; Neugebauer, Helmut; Sariciftci, Niyazi Serdar; Toppare, Levent Kamil (Wiley, 2010-12-15) D-A-D-type polymers are of high interest in the field of photovoltaics and electrochromism. In this study we report the synthesis and electrochemical properties of PPyBT along with its photophysical properties and photovoltaic performance. PPyBT is soluble in common organic solvents and both n- and p-type dopable, which is a desired property for conjugated polymers. During electrochemistry studies, the onset potentials of the polymer were determined as +0.2V for oxidation and -1.4V for reduction. Using thes...
