摘要：

The now tetracatenars bis[5-(3,4-dialkoxybenzylidine)aminotropolonato] copper(H) are mesogenic. As the 3,4-dialkoxy chains on the phenyl rings increase in length, the phase behavior shifts from calamitic to discotic (cohannar), the first case of a metallomesogen series to exhibit both calamitic and columnar phases. When n less than or equal to 12 the complexes melt to calamitic liquid crystals (specifically the smectic C phase), while for n greater than or equal to 13 the liquid crystal phases are columnar (specifically the phase columnar hexagonal phase) (C) 2002 Published by Elsevier Science B.V.
