A METHACRYLATE-BOUND PHOTOISOMERIZABLE CHROMOPHORE, METHODS FOR ITS SYNTHESIS AND OF ITS INTERMEDIATES

The invention discloses novel dicyanostilbene derivatives bound to a methacrylic moiety that can serve as an active chromophore in a 3-dimensional optical memory, processes for its synthesis and its intermediates.

Reaction of the Silver Salts of Arylnitroacetonitriles with 9-Bromofluorene. Synthesis of 9-(α-Cyanoarylidene)fluorenes

The silver salts 1a-d react with 9-bromofluorene to give both C- and O-alkylated products 2 and 3.The latter decompose to yield 9-fluorenone and the α-cyanooximes 5.The products 2 upon treatment with NaOH/EtOH eliminate HNO2 to afford 9-(α-cyanoarylidene)fluorenes 4 in 80percent yield. 9-Chloro-9-phenylfluorene reacts with salt 1a to give only C-alkylated product 6 in 70percent yield.
