Novel nucleoside analogues with base moieties containing pyrene groups have been synthesized and incorporated into oligodeoxyribonucleotides (ODNs). ODNs containing tandem pyrene residues at the 5'-end gave fluorescence spectra characteristic of eximers that were diminished by duplex formation of the ODNs with complementary strands.
