Principles of sequence-recognition in aromatic polyimides
Literature Information
Howard M. Colquhoun, Zhixue Zhu, Christine J. Cardin, Yu Gan
Pyrene-based molecular tweezers show sequence-specific binding to aromatic polyimides through sterically-controlled donor–acceptor π-stacking and hydrogen bonding; 1H NMR spectra of tweezer-complexes with polyimides having different sequence-restrictions show conclusively that the detection of long range sequence-information results from multiple tweezer-binding at adjacent imide residues.
