✦ Synopsis


The degree of circular polarization in the absorption of light by a thermally annealed film of chirally substituted polyfluorene depends strongly on the film thickness. This indicates that the exceptionally high dissymmetry ratios observed for these films originate on a nanoscopic level and are related to the long‐range correlation in the polymer chain orientation. Circular polarizations (see Figure) of up to 50 % can be reached.

The effect of high boiling point solvent on the residual stress behaviors of semiflexible structure poly(4,4Ј-oxydiphenylene pyromellitimide) (PMDA-ODA) and pseudo-rodlike poly(p-phenylene biphenyltetracarboximide) (BPDA-PDA) polyimide was investigated. As a solvent, a mixed solution of 20 wt % cycl
