✦ Synopsis

The fluorescence depolarization of proflavine groups incorporated into the backbone of aromatic polyimides has been measured in various solvents. The mean rotational relaxation times of the main chain depend on the structures of aromatic polyimides as planar semi-stiff chain polymers and differ from that of a low molecular analogue.

The emission anisotropies of PBLG-RhB [rhodamine B chemically bound to the terminal amino group of poly(7-benzyl L-glutamate)] have been measured in a semi-concentrated solution of PBLG. The results show that the extent of the aggregation behaviour of PBLG gradually increases with increasing concent
