title: A helix-turn-helix supersecondary structure based on oligo(phenanthroline dicarboxamide)s.
abstract: An artificial helix-turn-helix (HTH) supersecondary structure based on the oligo(phenanthroline dicarboxamide)s, in which the 2,2'-dimethoxy-1,1'-binaphthyl-6,6'-diamine subunit was utilized as the turn to impart a bias in the twist sense of the supersecondary structure, was reported. The HTH structure has been demonstrated by UV/vis, NMR, CD spectra, and X-ray crystal analysis.
