Abstract:
Linear and hyperbranched ladder polymers are facilely synthesized by a Pd(0) -catalyzed Suzuki polycondensation and Friedel-Crafts alkylation. The polymers show blue light emission with typical features of ladder polymers, such as well-resolved absorption and emission spectra, and small Stokes shifts. The polymers contain fewer structural defects and they exhibit good optical and thermal stability. No spectral change is observed after the films of ladder polymers are heated at 110 °C in air for 24 h.

Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
The extent of the...
