Synthesis and Crystallochromy of 1, 4, 7, 10??Tetraalkyltetracenes: Tuning of Solid??State Optical Properties of Tetracenes by Alkyl Side??Chain Length
Abstract We synthesized a series of 1, 4, 7, 10-tetraalkyltetracenes using a new 2, 6- naphthodiyne precursor and 2, 5-dialkylfurans as starting materials (alkyl= methyl to hexyl). Surprisingly, the solid-state color of the tetracenes ranges through yellow, orange, and red. Both yellow and red solids are obtained for the butyl derivative. Optical properties in solution show no marked differences; however, those in the solid state show characteristics that ...
