The present invention concerns functionalized photoreactive compounds of formula (I), that are particularly useful in materials for the alignment of liquid crystals. Due to the adjunction of an electron withdrawing group to specific molecular systems bearing an unsaturation directly attached to two unsaturated ring systems, exceptionally high photosensitivities, excellent alignment properties as well as good mechanical robustness could be achieved in materials comprising said functionalized photoreactive compounds of the invention.

A method of synthesizing a substituted cyclopentadiene compound. The synthesis comprises a step of cyclizing, in the presence of a phosphorous pentoxide/methanesulfonic acid reagent, an alpha,beta-unsaturated carboxylic acid, cycloalkyl ester compound to make a substituted cyclopentenone compound, and converting the substituted cyclopentenone compound to the substituted cyclopentadiene compound. Also, a method of synthesizing a substituted metallocene compound comprising a metal-(substituted cyclopentadienyl ligand) complex, wherein the substituted cyclopentadienyl ligand is made from the substituted cyclopentadiene compound. A metal-(substituted cyclopentadienyl ligand) complex and substituted metallocene compound made by the method and a substituted metallocene catalyst made therefrom.
