Pyridineâimide oligomers created by incorporating imide and pyridine units alternatively in sequence were successfully synthesized and found to form highly compact and stable helical conformations contributed by intramolecular H-bonds between the imide and both adjacent pyridines, and by the structural characteristics of the imide units.
