Abstract

The six-step synthesis of 2,3-di-n-hexadecyloxypentacene from benzoquinone as starting material is described. This rod-shaped molecule (ca 3.6 nm in the extended form) was shown to self-assemble into a fibrillar network.

Key words

cycloadditions - aldol reactions - linear acenes - Meerwein-Ponndorf reductions - pentacene derivatives

Gelation test: Solvent (1 mL) was added to a weighed amount of gelator in a septum-capped test tube (ca 6 cm length and 0.7 cm diameter) in order to obtain the desired concentration. The mixture was warmed (to the bp) until the solid dissolved. Then the mixture was allowed to cool to r.t. When a gel was formed (ca several min), the sample did not flow when the tube was inverted.
