Electrochemical and optical properties of novel donor-acceptor thiophene-perylene-thiophene polymers
Koyuncu, Sermet; Kus, Mahmut; Demic, Serafettin; Kaya, Ismet; Ozdemir, Eyup; Icli, Siddik (Wiley, 2008)In this study, donor-acceptor type thiophene-perylene-thiophene monomers were synthesized and polymerized by both oxidative polymerization using FeCl3 as catalyst and the electrochemical process. UV-vis, FTIR, H-1 NMR, and ... -
Electrochromic and electroluminescent devices based on a novel branched quasi-dendric fluorene-carbazole-2,5-bis(2-thienyl)-1H-pyrrole system
Koyuncu, Sermet; Usluer, Özlem; Can, Mustafa; Demic, Serafettin; Içli, Sıddık; Sarıçiftçi, Niyazi Serdar (Royal Soc Chemistry, 2011)We report here the synthesis of a novel branched quasi-dendric system, 9,9'-(9,9'-dihexylfluorene-2,7-diyl)bis[3,6-bis(2,5-bis(2-thienyl) pyrrol-1-yl)carbazole], (FCSNS), in four steps, followed by coating onto an ITO-coated ... -
A Novel High-Contrast Ratio Electrochromic Material from Spiro[cyclododecane-1,9 '-fluorene]bicarbazole
Usluer, Özlem; Koyuncu, Sermet; Demic, Serafettin; Janssen, Rene A. J. (Wiley-Blackwell, 2011)A novel electroactive spirocyclododecylfluorene monomer named 2,7-bis(carbazol-9-yl)-9,9'-spiro[cyclododecane- 1,9'-fluorene] (SFC) was synthesized and electrochemically polymerized to give a very stable multi-electrochromic ... -
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 ... -
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 ... -
