Isotropic and anisotropic magnetic field effect on the exciplex between all-s-trans-1,6-diphenylhexa-1,3,5-triene and 1,4-dicyanobenzene

Article Abstract:

The characteristics of the all-s-trans-1,6-diphenylhexa-1,3,5-triene (DPH) and 1,4-dicyanobenzene (DCB) exciplex are studied. Results show that both DPH and DCB exhibit isotropic and anisotropic magnetic field effects (MFEs). Magnetic fields increase exciplex luminescence while the maximum MFE occurs at the dielectric constant, epsilon = 10. Two types of charge-transfer complexes with varying stoichiometries were also determined based on the wavelength dependence of the field effect.

Interaction of 4-nitroquinoline-1-oxide with indole derivatives and some related biomolecules: A study with magnetic field

Article Abstract:

Laser flash photolysis and an external magnetic field are used for the study of interaction of 4-nitroquinoline-1-oxide (4NQO) with indole derivatives, amino acids, tyrosine and tryptophan and model proteins, lysozyme and bovine serum albumin. Results reveal that photoinduced electron transfer from indols to 4NQO is accompanied by subsequent proton transfer irrespective of the substitution at the N-1 position.

Electrostatic contributions to indole-lipid interactions

Article Abstract:

The role of electrostatic forces in indole-lipid is investigated. The results indicate that indole has a bimodal distribution in the lipid-water interface region, with distinct differences in the mechanism of lipid-indole interaction at either site.
