Three photochromic monomers containing a permanent dipole photochromic azobenzene group separated from the methacryloyl moiety by a polymethylene spacer, namely 4-(4-oxy-4@-cyanoazobenzene)but-1-yl methacrylate, 6-(4-oxy-4@-cyanoazobenzene)hex-1-yl methacrylate, and 8-(4-oxy-4@-cyanoazobenzene)oct-1
