title: A novel pyrene-guanidiniocarbonyl-pyrrole cation efficiently differentiates between ds-DNA and ds-RNA by two independent, sensitive spectroscopic methods.
abstract: At micromolar concentrations and equimolar conditions in respect to basepairs, a novel pyrene-guanidiniocarbonyl-pyrrole cation 1 exhibited a strong ICD signal at about lambda=300nm specifically upon the interaction with ds-DNA, while under the same conditions a new fluorescence maximum at lambda=480nm appeared exclusively upon the addition of ds-RNA.
