The Electrical Conductivities of Aromatic Diamine-Chloranil and -Tetracyanoethylene Charge-Transfer Complexes

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...

Mechanistic appraisal of the charge-transfer complexes of promethazine with chloranil: a modelling approach.

Various mechanisms are often used to explain the interaction between electron donors and acceptors. Commonly proposed mechanisms are those in which the acceptor interacts with the aromatic pi-systems in the donor molecule or the acceptor forms a weak interaction of the Lewis acid with Lewis base type. In this study, the above mechanisms were examined as well as other possible mechanisms. Promet...

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

Single-molecule charge transfer and bonding at an organic/inorganic interface: tetracyanoethylene on noble metals.

We have studied the structural and electronic properties of tetracyanoethylene (TCNE) molecules on different noble-metal surfaces using scanning tunneling spectroscopy and density functional theory. Striking differences are observed in the TCNE behavior on Au, Ag, and Cu substrates in the submonolayer limit. We explain our findings by a combination of charge-transfer and lattice-matching proper...
