Strapped porphyrin-based polymeric systems

Abstract

Inspired by functional systems in nature, chemists have created a number of intriguing and useful molecular systems from porphyrins and their metal complexes. Of the synthetic porphyrin derivatives developed to date, strapped porphyrins are unique because they have three-dimensional architectures based on a built-in two-dimensional porphyrin molecule. Consequently, the structures of strapped porphyrins can be customized through detailed molecular design, thereby allowing the synthesis of sophisticated molecular systems. Herein, we describe strapped porphyrin-based polymeric systems. In particular, we focus on molecular design concepts that are established in combination with photophysical, electronic and mechanical properties of polymeric materials.
