ABSTRACT
In the course of studies of the smectic F phase in N(p-n-alkoxybenzylidene)p-n-alkylanilines, we find that the material N(p-n-octyloxybenzylidene)p-n-decylaniline, 80. 10, provides yet another example, additional to 50. 6, exhibiting a smectic F phase below a high-ordered smectic B phase. The new phase sequence variant is ABF.
