New anionic surfactants and methods of preparation which are derived from aromatic or substituted aromatic molecules and alkenesulfonic acid. Wherein the aryl compound is alkylated and sulfonated in one-step with an alkene sulfonic acid prior to sulfonic acid neutralization. The methods allow the functional sulfonate group to be attached to the end of the alkyl chain rather than to the aromatic ring thus allowing for selective substituted groups, either branched, linear or alkoxylated or combinations thereof to be placed on the aryl compound prior to sulfonation and alkylation.

In one embodiment of the present invention, a novel fused polycyclic aromatic compound of the present invention is (a) a compound including a benzodichalcogenophenobenzodichalcogenophene (BXBX) skeleton further having an aromatic ring(s) located outside the BXBX skeleton, or (b) a compound including a BXBX skeleton in which a benzene ring is substituted with a heterocyclic ring. The compound can strengthen intermolecular interaction due to greater π electron orbits. This improves an electron field effect mobility of an organic semiconductor device that is manufactured by use of the compound as an organic semiconductor material.
