Abstract
Investigations have been carried out to probe the interactions between double stranded DNA and non-amphiphilic chromium(III) complexes, [Cr(en)3]3+ and [Cr(phen)3]3+ (en-ethylenediamine, phen-1,10 phenanthroline) in mixed monolayers with dihexadecyl phosphate (DHP). Under the experimental conditions, the results show that there is a specific binding mode between [Cr(en)3]3+ and DNA at air/water interface based on adsorption followed by a strong binding of [Cr(en)3]3+ to DNA based on H-bonding. In case of [Cr(phen)3]3+ the results indicate that after initial adsorption of DNA to the metal complex, partial intercalation of Cr(phen)33+ takes place in the strands of DNA.
