Unexpected chiral induction from achiral cationic polythiophene aggregates and its application to the sugar pattern recognition.
The aggregates of a cationic polythiophene (PT1) formed in poor solvent in the presence of sugars showed the distinct circular dichroism activity, the intensity being well correlated with the specific optical rotation [α] of sugars: therefore, the present system is useful as a novel sugar structure reading-out method.
