Pyrazole amino acid oligoamides were prepared on polyethylene glycol starting from nitro pyrazole carboxylic acids or protected pyrazole amino acids. The polymer support facilitates product isolation during synthesis and makes the target oligoamides soluble in chloroform and water. This allows the determination of their binding properties towards peptides. Moderate affinity, which increases with the number of pyrazole units, is observed in chloroform and water.

Novel ferroelectric liquid crystals based on fused thieno[3,2-b]furan and thieno[3,2-b]thiophene cores, Liquid Crystals, 33:9, 987-996 To link to this article: http://dx.Several series of new benzofused thieno[3,2-b]furan-and thieno[3,2-b]thiophene-based derivatives have been synthesized and their mesomorphic properties investigated. All the studied compounds exhibit a SmC* phase with very wide temperature interval. Additionally, some types of the compounds show the cholesteric, SmA or blue phase. In the ferroelectric SmC* phase we evaluated physical properties of relevance for possible applications.

The synthesis of a new heterocyclic core has been developed. Its standard derivatisation afforded new types of FLC's and their physical properties were determined.
