Determination of Trimethoprim Based on Charge-Transfer Complexes Formation

A spectrophotometric study concerning the interaction between Trimethoprim (TMP) ,Sulfamethoxazole (SFMx), as n-donor and 2,3-dichloro-5,6- dicyano-P-benzoquinine (DDQ) and chloranilic acid (CA) as π-acceptor were been performed at 25°C. The results of interaction of CA and DDQwith TMP indicate the formation of a 1:1, 1:2, charge transfer complexes through non equilibrium reactions. In the case...

determination of trimethoprim based on charge-transfer complexes formation

Mixed valency in organic charge transfer complexes.

Mixed-valence (partial charge transfer state) and segregated stacking are the key factors for constructing organic metals. Here, we discuss the ionicity phase diagrams for a variety of charge transfer systems to provide a strategy for the development of functional organic materials (Mott insulator, semiconductor, superconductor, metal, complex isomer, neutral-ionic system, etc.).

Charge transfer complexes of paraquat with drugs

Molecular complexes of paraquat (PQ) with a few drug intermediates in alkaline medium, viz. 2,4,6-trimethylphenol, 4-benzyloxyphenol, 2-cyanophenol, 4-cyanophenol and a few drugs, viz. diclofenac sodium, salmeterol, omeprazole, esomeprazole and pantoprazole in methanol have been studied spectrophotometrically. All the complexes exhibit one charge transfer band each in the region where neither o...

Charge transfer complexes of chloranil with drugs

The study of charge transfer (CT) complexes of chloranil with drugs (Naproxen, Nerolin, Methyl anthranilate, Isoxsuprine and Nylidrin) showed that there is a significant interaction between the acceptor and donors as evidenced by colour changes and absorption spectra. From the position of CT bands, the ionization potentials (IPs) of donors were evaluated using appropriate equations. The donor’s...
