There is disclosed a method of preparing a branched benzofuran compound comprising a core moiety which contains at least one aromatic ring and which has at least three substituted or unsubstituted benzofuran groups covalently linked thereto. The method comprises the steps of
(i) forming an intermediate ethynylene compound in which at least three benzene rings are each linked to the core moiety via an ethynylene bond, and where each benzene ring is substituted at the ortho position (relative to the position of the ethynylene bond) by a blocked carbonyloxy group,
(ii) deblocking the carbonyloxy groups, and
(iii) effecting ring closure by reaction between the deblocked carbonyloxy groups and the adjacent ethynylene bonds to form the furan rings of the benzofuran groups, whereby to produce the branched benzofuran compound.
