Cryptoannulenic behavior of monoazacyclacenes

Türker, Burhan Lemi
Within the framework of Huckel molecular orbital theory, it has been found that similar as cyclacenes monoazacyclacenes exhibit some cryptoannulenic behavior, and their angle of total pi-electron energies fluctuates within the series, depending on the size and type of the peripheral circuit (4m or 4m + 2 type). However, this effect in monoazacyclacenes is less pronounced as compared to cyclacenes.


On the cryptoannulenic behavior of certain corannulenes
Türker, Burhan Lemi (Informa UK Limited, 1996-01-01)
Cryptoannulenic behavior of certain corannulenes is investigated within the Framework of Huckel molecular orbital theory. It has been found that the cryptoannulenic behavior of the corannulenes studied, generally arises from the type of their individual peripheral rings (4m or 4m + 2) but not from the type of the inner or outer periphery of the whole corannulene system.

A quantum chemical study, based on DFT theory is presented which considers certain selenium-containing naphthalene derivatives, including a keto group together with a Se atom embedded in either a five- or six-membered ring fused with naphthalene moiety. The corresponding enol structures also are considered. The quantum chemical and IR data collected are analyzed and NICS(0) values have been obtained.
Electrochemical and Optical Studies of Furan and Thieno[3,2-b]thiophene End Capped Benzotriazole Derivatives
AKBASOGLU, Naime; BALAN, Abidin; BARAN, Derya; Çırpan, Ali; Toppare, Levent Kamil (Wiley, 2010-12-01)
Two new 2-dodecyl benzotriazole (BTz) based donor-acceptor-donor (DAD) type polymers were synthesized and characterized in terms of their electrochemical and spectral properties. These DAD type polymers were synthesized electrochemically from furan or thieno[3,2-b]thiophene (TT) endcapped BTz monomers. Furan based and thieno[3,2-b]thiophene based monomers showed monomer oxidations at 1.15 and 1.25 V, respectively, which eased the formation of conducting polymer films without overoxidation. Cyclic voltammetr...
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...
Polymerization and characterization of trihalophenolato cerium(IV) complexes in the solid state and in the melt
Senturk, O; Kisakurek, D (Informa UK Limited, 2003-01-01)
The synthesis of trihalophenolate cerium (IV) complexes from an aqueous solution and their characterizations by means of FTIR, DSC, elemental analyses, mass spectroscopy, and magnetic susceptibility measurements are described. The thermal polymerizations of these complexes were carried out in the solid state and in the melt. Structural analyses of polymers were performed by H-1-NMR, C-13-NMR, and FTIR spectroscopic analyses; T-g by differential scanning calorimetry; as well as the molecular weights by visco...
