Unsaturated ladder polymers: Structural variations and improved molecular weights

Abstract

All‐carbon ladder polymers with extended π systems are of interest for electroluminescence and photovoltaics applications. The synthesis of two new ladder polymers (e.g. see Figure) exhibiting relatively high molecular weights and pronounced film‐forming abilities, is reported. It is also shown that the degree of saturation in these polymers can be chemically closly controlled. magnified image
