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 these values, HOMO and LUMO energy levels were calculated. The photovoltaic properties of PPyBT were also studied. PL studies showed that there is a charge transfer between PPyBT (donor) and PCBM (acceptor).

Electrochemical properties of a new star-shaped pyrrole monomer and its electrochromic applications Ak, Metin; Ak, Mine Sulak; Toppare, Levent Kamil (Wiley, 2006-08-02) A new monomer, 2,4,6-tris(4-(1H-pyrroI-1-yl) phenoxy)-1,3,5-triazine (Tria-Py) was synthesized via the reaction,of 4-(1H-pyrrol-1-yl)phenol with 2,4,6-trichloro-1,3, 5-triazine. It was electrochemically polymerized in a dichloromethane/acetonitrile solvent mixture. The polymer P(Tria-Py) was characterized via CV, FTIR, SEM and uv-vis spectroscopy. Spectroelectrochemical analysis revealed electronic transitions at 346, 508 and 665, nm, revealing pi to pi* transitions, and polaron and bipolaton band formation...
Cycled-fused-borazines - MNDO and AMI treatments Türker, Burhan Lemi (Elsevier BV, 2003-11-17) The Huckel type cycled-fused-borazines which are analogous to cyclacenes are considered for the semiempirical molecular orbital treatment at the level of MNDO and AMI type calculations. The structures having 3-10 arenoid rings (R) are considered. It has been found that they should be thermally stable and exogenic. Moreover, these properties get more and more as R increases. The systems exhibit no cryptoannulenic effect on any of the properties presently studied, showing that the peripheral circuits, unlike ...
Synthetic Design of Polyester Electrolytes Guided by Hydrophobicity Calculations Yıldırım, Erol; Peretic, Matthew J.; Pasquinelli, Melissa A.; Mathers, Robert T. (American Chemical Society (ACS), 2016-10-25) Partition coefficients (LogP) help to quantify hydrophobicity, which can be used to guide the design of polymer electrolytes with properties. Thus, this study combined synthetic experiments and modeling to produce polyester electrolytes that solubilize lithium salts. These polyester electrolytes were derived from natural sources and polymerized with different ratios of polyols (diglycerol, glycerol, and diethylene glycol) and citric acid in the presence of lithium salts (LiTf and LiTFSI). The Fisher esterif...
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...
Resveratrol and its analogues resveratrol-dihydroxyl isomers: semi-empirical SCF-MO calculations Erkoç, Şakir; Keskin, N; Erkoc, F (Elsevier BV, 2003-08-01) The structural and electronic properties of resveratrol and its three analogues resveratrol-dihydroxyl isomers have been investigated theoretically by performing semi-empirical self-consistent field molecular orbital theory calculations. The geometry of the systems have been optimized and the electronic properties have been calculated at the level of AMI method.
