This paper presents results of our studies of a full homologous series of 4-(4′-alkyloxyphenylazo)benzoyl chlorides. Until now these compounds have been used only as intermediates for more complex materials and their properties were not investigated as ac

Spontaneous mirror-symmetry breaking is a fundamental process for development of chirality in natural and in artificial self-assembled systems. A series of triple chain azobenzene based rod-like compounds is investigated that show mirror-symmetry breaking
4-Methylresorcinol based bent-core liquid crystals with azobenzene wings-a new class of compounds with dark conglomerate phases

Stochastic achiral symmetry breaking in soft matter systems, leading to conglomerates of macroscopically chiral domains (so-called dark conglomerate = DC phases) is of contemporary interest from a fundamental scientific point of view as well as for numero

, p. 669 - 680 (2013/07/26)
The paper presents the synthesis and mesomorphic behavior of two new series of bent core liquid crystalline compounds based on a 1,3-dihydroxybezene core and containing a cholesteryl 6-oxyhexanoate wing. The two series were obtained by esterification of t
Synthesis and physico-chemical properties for 2-oxochromen-6-yl 4-(4-alkoxyphenylazo)benzoates
Morita, Yuki,Uemura, Hiroshi,Shimoi, Kentaro,Kasatani, Kazuo,Okamoto, Hiroaki
, p. 163 - 172 (2011/08/02)
This paper describes the preparation and thermal properties for homologous series of 2-oxochromen-6-yl 4-(4-alkoxyphenylazo)benzoates (compounds 1-n). Compounds 1-n show nematic phase exclusively, where the nematic-isotropic phase transition temperatures are between 293° C for 1-4 and 256° C for 1-8. Interestingly, compound 1-8 exhibits smectic A and re-entrant nematic phases in addition to the nematic one. The smectic A phase are characterized using a small angle X-ray diffraction study, indicating the smectic A phase has a partially bilayer molecular arrangement.
