摘要: Synthesis of 1,6- and 1,8-triazolylpyrenes their incorporation into oligonucleotides is described. In hybrids, triazolylpyrenes adopt interstrand stacking interactions. Exciton coupling observed for the duplex containing a pair 1,6-isomer indicating well-defined helical arrangement triazolylpyrene building blocks. Triazole substitution results in pronounced red-shifts monomer as well excimer fluorescence. Furthermore, quantum yields formed excimers are remarkably high.
