Abstract
Re-examination of the bis-(4′-n-alkoxy-benzylidene)-1,4–phenylenediamines, particularly the heptyloxy homologue, by optical microscopy and differential scanning calorimetry has confirmed the existence of two hitherto unclassified smectic phases, which are now assigned the code letters J and K (SJ andSkKeywords
