Abstract:
The present invention generally relates to various dinaphthothiophene compounds and processes for preparing these compounds.

Claim (Index 27):
A process for preparing a dinaphthothiophene compound, the process comprising:\n formylating 3,4-dibromothiophene to form 4-bromothiophene-3-carbaldehyde; reacting, in the presence of a catalyst comprising palladium, a base, and organic solvent, 4-bromothiophene-3-carbaldehyde with a phenylethenyl boronic compound of Formula C-1: to form a 3-formyl-4-styrylthiophene compound of Formula C-2: reacting, in the presence of sodium hydride, the 3-formyl-4-styrylthiophene compound of Formula C-2 with a 4-substituted phosphonic acid diethyl ester compound of Formula C-3: to form a compound of Formula C-4: irradiating the compound of Formula C-4 with UV light in the presence of iodine and propylene oxide to form the dinaphthothiophene compound of Formula III-A: wherein R 3  is hydrogen, hydroxy, substituted or unsubstituted C 1 -C 20  alkyl, or substituted or unsubstituted aryl and R 4  is hydrogen, hydroxy, substituted or unsubstituted C 1 -C 20  alkyl, or substituted or unsubstituted aryl.
