Abstract

Abstract We have synthesized 1, 4, 7, 10-tetraisoalkyltetracenes from a 2, 6-naphthodiyne precursor and 2, 5-diisoalkylfurans as the starting materials (isoalkyl: isopropyl, isobutyl, and isopentyl). The tetracene molecules exhibited crystallochromy: The solid-state colors of the isopropyl, isobutyl, and isopentyl derivatives were yellow, red, and orange-yellow, respectively. In contrast, there were no marked differences in the optical properties of ...
