Spectroscopic Study of the Complexation of Meso-Tetraphenylporphyrin with -Acceptors DDQ and TCNE in Chloroform Solution
Formation of the molecular complexes between meso-tetraphenylporphyrin (TPP) and the p-acceptors 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) and tetracyanothylene (TCNE) in chloroform solution was investigated spectrophotometrically. The formation constants of the resulting 1:1 molecular complexes were determined using the Benesi-Hildebrand and Nash methods. The TPP-DDQ pro...
متن کاملsynthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...

متن کاملBreathing some new life into an old topic: chalcogen-nitrogen π-heterocycles as electron acceptors.
Recent progress in the design, synthesis and characterization of chalcogen-nitrogen π-heterocycles, mostly 1,2,5-chalcogenadiazoles (chalcogen: S, Se and Te) and their fused derivatives, possessing positive electron affinity is discussed together with their use in preparation of charge-transfer complexes and radical-anion salts-candidate building blocks of molecule-based electrical and magnetic...
متن کاملPhotoinduced electron transfer and geminate recombination for photoexcited acceptors in a pure donor solvent.
Photoinduced electron transfer and geminate recombination are studied for the systems rhodamine 3B (R3B(+)) and rhodamine 6G (R6G(+)), which are cations, in neat neutral N,N-dimethylaniline (DMA). Following photoexcitation of R3B(+) or R6G(+) (abbreviated as R(+)), an electron is transferred from DMA to give the neutral radical R and the cation DMA(+). Because the DMA hole acceptor is the neat ...
