Carbazole-based organic dye sensitizers for efficient molecular photovoltaics
Zafer, Ceylan; Gultekin, Burak; Ozsoy, Cihan; Tozlu, Cem; Aydin, Banu; Icli, Siddik (Elsevier, 2010)Efficient dye sensitizers N,N'-dialkylcarbazolocarbazole derivatives BG-501 and BG-502 were synthesized and characterized. UV-vis, 1H NMR and CV were used for the structural characterization. The aim of the synthesis of ... -
Highly Soluble Polyoxyethylene-Perylene diimide: Optical, Electrochemical and Photovoltaic Studies
Haklı, Özgül; Zafer, Ceylan; Dinçalp, Haluk; Aydın, Banu; Can, Mustafa (Chem Soc Pakistan, 2011)The synthesis and optical properties of a new dye molecule [PERKAT] were reported. The molecular structure of PERKAT was characterized by FT-IR and H-1 NMR. Optical properties of PERKAT were investigated by UV-Vis absorption, ... -
New perylene derivative dyes for dye-sensitized solar cells
Zafer, Ceylan; Kuş, Mahmut; Türkmen, Gülşah; Dinçalp, Haluk; Demic, Şerafettin; Kuban, Baha; Içli, Sıddık (Elsevier, 2007)We have studied the influence of the spacer alkyl chain length of perylenemonoimide (PMI) dyes on the device performance in dye-sensitized solar cells (DSSCs). We observed that the dyes with longer and brunched alkyl chains ... -
Optical and electrochemical properties of polyether derivatives of perylenediimides adsorbed on nanocrystalline metal oxide films
Kus, Mahmut; Hakli, Oezguel; Zafer, Ceylan; Varlikli, Canan; Demic, Serafettin; Ozcelik, Serdar; Ieli, Siddik (Elsevier, 2008)We report optical and electrochemical properties of polyether derivatives of perylenediimides (PDIs) thin films formed in various materials (semiconductor, insulator, amorphous and self-assembly). Perylenediimides adsorbed ... -
Optical and photovoltaic properties of salicylaldimine-based azo ligands
Dincalp, Haluk; Yavuz, Sinem; Hakli, Oezguel; Zafer, Ceylan; Ozsoy, Cihan; Durucasu, Inci; Icli, Siddik (Elsevier Science Sa, 2010)A series of azo dyes containing salicylaldimine-based ligands as side chains were prepared and characterized. Absorption and emission data in five solvents of different polarities were studied. Photoirradiation studies ... -
Synthesis and Spectroscopic Properties of a Novel Perylenediimide Derivative
Haklı, Özgül; Dincalp, Haluk; Zafer, Ceylan; Demic, Serafettin; Colladet, Kristof; Vanderzande, Dirk; Icli, Siddik (Chem Soc Pakistan, 2011)A novel symmetric 3,4,9,10-perylenetetracarboxylic acid derivative (PDI1) dye based on thiophene donor group was synthesized and characterized by FT-IR and H-1 NMR. Cyclic Voltammetry analysis is performed to determine the ... -
Synthesis of an amphiphilic ruthenium complex with swallow-tail bipyridyl ligand and its application in nc-DSC
Sahin, Cigdem; Tozlu, Cem; Ocakoglu, Kasim; Zafer, Ceylan; Varlikli, Canan; Icli, Siddik (Elsevier Science Sa, 2008)An amphiphilic swallow-tail bipyridyl ligand, 4,4'-bis(dihexylmethyl)-2,2'-bipyridine, and its heteroleptic ruthenium (II) complex were synthesized starting from dichloro-(p-cymene) ruthenium (II) dimer. The complex was ...
