  Synthesis of 4-(1H,1H-perfluoroalkoxy)-4′-(6-methacryloyloxy-hexyloxy)-azobenzenes and their liquid crystalline intermediates

  摘要：

  The synthesis and characterization of 4-(1H,1H-perfluoroalkoxy)-4'-(6-methacryloyloxy-hexyloxy)-azobenzenes with different lengths of the fluorinated tail group (C-2-C-8) and their liquid crystalline intermediates, starting from 1H,1H-perfluoroalkyl-p-nitrophenyl-ethers is described. The liquid crystalline properties of the compounds were studied by differential scanning calorimetry, polarizing optical microscopy and X-ray diffraction methods. In contrast with their non-fluorinated analogues, all the liquid crystalline products display smectic mesophases caused by the fluorination of the tail group. (C) 1997 Elsevier Science S.A.

  Various synthetic approaches to fluoroalkyl p-nitrophenyl ethers

  摘要：

  Homologous 1H,1H-perfluoroalkyl p-nitrophenyl ethers (alkyl = C-2-C-8) were synthesized using different methods. The results are discussed in context with contradictory comments of the literature. The fluoroalkoxylation of p-chloronitrobenzene occurs in only one step, but it is limited to small fluoroalkyl groups. The fluoroalkylation of p-nitrophenol via sulphonic acid esters is a better synthetic route. Differences in reactivity and yield between tosylates, mesylates and triflates are found and discussed. The preferred synthesis includes the use of trifluoromethane sulphonic acid esters.
