Abstract
The synthesis and characterization of 1-(4-hydroxy-4'-biphenylyl)-2-(4-hydroxyphenyl)decane (TPD) and of 10-bromo-1-(4-hydroxy-4'-biphenylyl)-2-(4-hydroxyphenyl)decane (TPD-b) are described. Polyetherification of TPD with α,ω-dibromoalkanes containing from 6 to 10 methylene units leads to the model polyethers TPD-X (where X=6-10 and represents the number of methylene units in the flexible spacer). TPD-X with X=6, 8, and 10 exhibit an enantiotropic nematic mesophase, while those with X=7 and 9 are glassy
