Abstract

Front Cover: Geometric squeezing of the poly(phenylene vinylene) repeating units from conventional para‐connectivity to the ortho isomeric state induces considerable perturbation of the delocalized π–electron system. Shortened conjugation lengths and significant blue‐shifts of UV‐vis absorption and photoluminescence characteristics are the consequences. Creative graphic support in catchy visualization of that squeezing effect provided by Mr. Christian Krupp, WKC project, is gratefully acknowledged. Further details can be found in the article by V. Rittscher, S. Kuch, and M. Rehahn* on page 814.
