✦ Synopsis

The synthesis of 4-vinylstilbenes was accomplished by the Heck and Wittig reactions. Bromination of polystyrene was achieved by an iron-catalyzed electrophilic substitution reaction. Polymer-analogous coupling reactions of styrenes with respect to stilbenes with poly(bromostyrene)s was accomplished by Heck-reactions under optimized reaction conditions and is reported with respect to the molecular weight of the poly(bromostyrene)s. Thermal and optical properties are discussed with respect to lightemitting diode applications.
