Hence the lactam unit of PVP is considered to be an active site to form charge transfer complex with C = O group of MPDMAPP in the bulk state or in solution (3).
These absorption results indicate that the MPDMAPP interacts with PVA + PVP matrix via intermolecular hydrogen bonding and hydrophobic interaction and forms the charge transfer complex or charge cluster groups.
The change in colour of the composite film from bluish-grey to red is attributed to an electron injection from the ITO conduction band into the composite, which led to cathodic reduction of Mo(VI) to Mo(V) and, as a result, to disrupting the charge transfer complex. The anodic polarization, in turn, caused the oxidation of Mo(V) to Mo(VI), accompanied by a proton injection from the electrolyte to the composite film, which led back to the formation of a charge transfer complex involving heteropolyanions and polymer molecule.
Ferrocene is known to readily form charge transfer complexes (CTCs) with alkyl halides, as evidenced by the appearance of a feature indicative of a charge transfer complex at ~310 nm; subsequently, upon irradiation, the complex dissociates into the ferrocenium ion, chloride ion, and alkyl radical (Fig.
With literature references indicating that ferrocene derivatives complex with alkyl chlorides, the mixture of ferrocene and benzyl chloride forms a charge transfer complex ([K.sub.assoc, 310 nm] = 1.04 L [mol.sup.-1]).
The method is based on formation of a 1:1 charge transfer complex of promethazine, diphenhydramine, desloratadine, levocetirizine and loratadine with curcumin.
Once initiated, polymerization propagates through both a charge transfer complex and free monomers, and both mechanisms can be operating at the same time (2).
Summary: A charge transfer complex is formed when antihistaminic drug react with m- dinitrobenzene in basic medium.
The widely recognised particular interactions are hydrogen bonds, however other possible interactions to deliberate are ionic, dipole-dipole, acid-base, cation- p (cations interacting through aromatic rings) and charge transfer complexes [7, 8].

I developed Nuclear Magnetic Resonance facilities for the department, and worked on hydrogen bonding, charge transfer complexes, and structural chemistry (with Stan Tarbell, a leader in antibiotics chemistry).
