The structure of the monomer (R)-1-O-[4-(1-pyrenylethynyl)phenylmethyl]glycerol () in twisted intercalating nucleic acids (TINA) was optimized for stabilizing interactions between the intercalator and surrounding nucleobases when used as a triplex forming oligonucleotide (TFO). Enhancement of pi-pi interactions with nucleobases of the TFO was achieved by increasing the aromatic surface using the (
