We report a unimolecular system functioning as a combinatorial logic circuit for half-subtractor. The emission characteristics can be modulated by chemical inputs, and when followed at two different wavelengths, two functionally integrated logic gates XOR and INHIBIT are obtained. Both logic gates function in the emission mode, and with very large differences in the signal intensity allowing unequivocal assignment of logic-0 and logic-1.

Electronic properties of carbon nanotoroidal structures Yazgan, E; Tasci, E; Malcıoğlu, Osman Barış; Erkoc, S (Elsevier BV, 2004-07-26) Electronic properties of five carbon nanotori (C-170, C-250, C-360, C-520, and C-750) have been investigated by performing Extended-Huckel type calculations. Carbon nanotori considered is of Fonseca type having five-fold symmetry. It has been found that highest occupied molecular orbital-lowest occupied molecular orbital gaps of nanotori considered are very small, thus they may contain mobile electrons; pentagons and heptagons in the knee-regions act as an electron trap; and all the nanotori have a DOS dist...
Autonomous Shuttling Driven by an Oscillating Reaction: Proof of Principle in a Cucurbit[7]uril-Bodipy Pseudorotaxane Buyukcakir, Onur; Yasar, F. Tuba; BOZDEMİR, Özgür Altan; Icli, Burcak; AKKAYA, Engin Umut (American Chemical Society (ACS), 2013-03-01) A bipyridinium dication-substituted Bodipy fluorophore, with a terminal carboxylic acid function, provides two alternative stations for cucurbit[7]uril. Changing pH from basic to acidic results in shuttling of the cucurbit[7]uril from one station to another. In addition, this shuttling is accompanied by a change in the emissive properties of the Bodipy dye, which is only observed in the presence of cucurbit[7]uril. More striking, is a demonstration of autonomous shuttling of the pseudorotaxane system in an ...
Efficient one-pot synthesis of cyanoferrocene from ferrocenecarboxaldehyde using NH2OH center dot HCl/KI/ZnO/CH3CN system KIVRAK, Arif; Zora, Metin (Elsevier BV, 2007-05-01) A new and efficient one-pot synthesis of cyanoferrocene from ferrocenecarboxaldehyde is described by employing the NH2OH center dot HCI/KI/ZnO/CH3CN system.
INFLUENCE OF MEMBRANE-COMPONENTS ON THE STABILITY AND DRUG-RELEASE PROPERTIES OF REVERSE-PHASE EVAPORATION VESICLES (REVS) - LIGHT-SENSITIVE ALL-TRANS RETINAL, NEGATIVELY CHARGED PHOSPHOLIPID DICETYLPHOSPHATE AND CHOLESTEROL Gürsel, Mayda (Informa UK Limited, 1995-11-01) Incorporation of a negatively charged phospholipid, dicetylphosphate, initially increased encapsulation efficiency (from 12 to 24%) but beyond 5% (molar) a detrimental effect was observed. Rate of drug release from REVs was, for most cases, found to be bi-phasic implying partitioning between the lipid bilayer and the aqueous compartment. It was not possible to prepare liposomes with more than 1% (molar) all-trans retinal (ATR) as a membrane component. When ATR was reduced to 0.5% (molar), encapsulation effi...
Carboligation reactions with benzaldehyde lyase immobilized on superparamagnetic solid support Sopaci, S. Betuel; Turan, Ilke Simsek; Tural, Bilsen; Volkan, Mürvet; Demir, Ayhan Sıtkı (Royal Society of Chemistry (RSC), 2009-01-01) Histidine-tagged recombinant benzaldehyde lyase (BAL, EC 4.1.2.38) was efficiently immobilized to surface-modified magnetic particles with affinity ligand binding. In addition to conventional benzoin condensation reactions, two important representative BAL-catalyzed carboligation reactions, were also performed with this magnetically responsive biocatalyst. The results obtained from the carboligation reactions that were performed with this simple and convenient heterogenous biocatalyst were comparable to tha...
