New fluorene-based chiral copolymers with unusually high optical activity in pristine and annealed thin films

Polyfluorene ( PF )-based chiral alternating copolymers, i.e. , PFPh and PFTh , were successfully synthesized to obtain high circular dichroism (CD) in pristine thin films. By tethering chiral side-chains to the fluorene moiety, the resultant PFPh and PFTh films intriguingly exhibited high CD even i...
