Undulation textures at the phase transitions of some alkyloxybenzoic acids
A. Sparavigna, A. Mello, G. Massa
We observed undulated smectic textures for some compounds of the 4,n-alkyloxybenzoic (nOBAC) acid series, at transitions between the smectic and the isotropic phase and between the…
Growth of toric domains in the smectic phase of oxadiazoles
A. Sparavigna, A. Mello, B. Montrucchio
In a previous paper (Phase Transitions, 80(9), 987, 2007) we discussed the smectic and nematic textures of some mesomorphic oxadiazole compounds with terminal Cl-substituent. Optic…
Fan-shaped and toric textures of mesomorphic oxadiazoles
A. Sparavigna, A. Mello, B. Montrucchio
When a family of non symmetrical heterocycled compounds is investigated, a variety of mesophases can be observed with rather different features. Here we report the behaviour of sev…
Texture transitions in the liquid crystalline alkyloxybenzoic acid 6OBAC
A. Sparavigna, A. Mello, B. Montrucchio
The 4,n-alkyloxybenzoic acid 6OBAC has a very rich variety of crystalline structures and two nematic sub-phases, characterised by different textures. It is a material belonging to…
Texture transitions in binary mixtures of 6OBAC with compounds of its homologous series
A. Sparavigna, A. Mello, B. Montrucchio
Recently we have observed in compounds of the 4,n-alkyloxybenzoic acid series, with the homologous index n ranging from 6 to 9, a texture transition in the nematic range which subd…
