Explorations in Supramolecular Chemistry: Part 1. Development of a Modular System for the Study of Self-Organization Through Microphase Segregation in Discotic Liquid Crystals. Part 2. Investigation of Deazapterins and Naphthyridines as End-Groups for Supramolecular Polymers
… directional hydrogen bonds for the formation of supramolecular polymers was explored. Synthetic routes toward supramolecular polymer end-groups based upon the 2-amino-5-deazapterin and 2,7-diamino-[1,8]-naphthyridine ring systems were pursued. While it was found that the end-groups could be made, …
