摘要：

The blue emission of ladder-type poly(para-phenylene) films is unstable under heat treatment due to the formation of aggregates that emit yellow light. Novel statistical copolymers possessing ladder-type oligo(para-phenylene) segments connected via twisted phenylene spacers are used to suppress the formation of these aggregates and to obtain blue emission stable under annealing.
