Geodesic Phenine Frameworks

Abstract

Abstract The planar trigonal structure of 1,3,5-trisubstituted benzene, named phenine, has been adopted as basic units of polygonal networks to shape nanometer-sized curved organic π-molecules. The phenine design allows for concise syntheses of large carbonaceous molecules reaching 4 kDa by stitching geodesic lines with aryl coupling reactions. In this Account, the development of the defective nanocarbon molecules, i.e., geodesic phenine frameworks, is summarized to overview unique structural/electronic features.
