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
## Abstract New hydrophilic photochromic polymeric systems containing sideβchain azobenzene groups were synthesized by radical copolymerization of 4βacryloyloxyazobenzene with hydrophilic acrylic comonomers containing in the side chain either amide or quaternary onium groups. In all cases copolymer
An -amino carboxylic acid monomer that contained a nonlinear optical (NLO) chromophore was prepared by a convergent synthesis. Strategies for selective protection/deprotection of the amino and carboxylic acid functionalities were developed. The protected monomer, 4-[N-(4-benzyloxycarbonyl)butyl-N-me
