Series of 2-(3-fluoro-4-alkoxy-1,1-biphenyl-4-yl)-benzoxazole liquid crystals(coded as nPF(3)PBx)are prepared,where a lateral fluorine substituent,as well as methyl,chlorine and nitro terminal groups are introduced into the molecules to investigate the effects of different polar substituents on the liquid crystals properties.
