Studies of the photophysical properties of head-to-head polystyrene, block copolymers poly(butadiene-b-styrene) and polystyrenes of various sequence length of styrene chromophore and regular copolymers of :t-methylstyrene indicate that interactions between phenyl chromophores located distantly upon

Al~a'aet--Energy migration and intramolecular excimer formation have been examined in copolymers of 1-vinyinaphthalene and methyl acrylate. The degree of depolarization of fluorescence, p-1 from glassy solutions of the copolymers in 2-methyltetrahydrofuran at 77 K was used to characterize the extent

## Abstract The homopolymer of 2‐__tert__‐butyl‐6‐vinylnaphthalene (BVN) and its copolymers with styrene were prepared to examine the effects of the bulky __tert__‐butyl groups on singlet energy migration and excimer formation among the naphthalene chromophores. The intensity of naphthalene excimer
## Abstract The time‐resolved fluorescence behavior of polystyrene and a series of styrene–methyl methacrylate copolymers has been examined by using pulsed laser excitation. Although the photophysical characteristics of styrene‐ and naphthalene‐containing polymers may be described by the same gener
