Progress Toward a Propeller-Shaped Oligophenyl Lactone with Reversible Geometry Switching

Abstract

Planar conjugated organic molecules have unique spectroscopic and electronic properties. This study focused on molecules containing the 6H-benzo[c]chromen-6-one subunit because they should be both planar and conjugated, but should also readily switch their geometries in varying pH environments. The purpose of this study was to describe the progress toward a new organic-soluble propeller-shaped oligophenyl trilactone with C3h symmetry.
