Inside Cover: Highly Birefringent Materials Designed Using Coordination Polymer Synthetic Methodology (Angew. Chem. Int. Ed. 46/2007)
Birefringent materials have different refractive indices in two directions and are ubiquitous in both linear and nonlinear optical applications. In their Communication on page 8804 ff., D. B. Leznoff and co-workers generate new types of highly birefringent materials (Δn>0.39) using coordination polymer methodology. The picture illustrates the optical phenomenon of birefringence, namely the double image of the polymer structure generated by a commercially utilized birefringent (Δn=0.17) calcite crystal.
