Abstract
CD and uv-visible absorption studies with several tetracationic water- soluble porphyrin derivatives show that some of these species can serv e as probes to discriminate between A- and B-conformational forms of s ingle-stranded polynucleotides. It is also observed that these porphyr ins can participate in the formation of double helices by forming tran sient intermediate complexes enroute to duplex formation.
