抄録

The molecular orientation and the molecular motion of pyrene chromophore which is incorporated into polymer LB films were studied by UV-vis spectroscopy and fluorescence anisotropy measurement. The pyrene orientation was largely affected by the side alkyl chains of the polymers. The pyrene chromophore orients perpendicular to its layer plane in N-dodecyl acrylamide polymer (p(DDA)) LB films, while the pyrene orients parallel to its layer plane in tert-pentyl acrylamide polymer (p(tPA)) LB films. Both polymer LB films show high anisotropy values, indicating that the molecular motion of pyrene chromophore is restricted in the polymer LB films.
