“…84 We also carried out another modification of the series by replacing cholesterol side chain with thioalkyl substituted heterocycle unit (Scheme 28). 85 Precursors 123a-b was prepared from p-iodobenzoate in three steps via amidation, cyclization and subsequent thioalkylation (Scheme 28). A l l t h e c o m p o u n d s o f t h e s e r i e s displayed only one mesophase as evident from DSC experiment.…”

The liquid crystal structure is a distinct phase of matter seen between crystalline and isotropic regions. There are many types of glossy liquids, depending on the composition. They have a different type of electronic device and display. As a result, development and integration of this type of extraordinary materials is required. Here, we have outlined the preparation route and properties of the different compounds which show this type of properties.

“…On this ground, a number of interesting ethynyl-bridged 2,5-disubstituted 1,3,4-oxadiazoles were studied for their luminescence, 4 as fluorescent liquid crystals, 5 selective sensors for nitro compounds, 6 or ligands for coordination polymers with one-, two-, or three-dimensional structures. 7 Influence of the extended conjugation through the alkynyl chain was also investigated for various oligoyne-bridged 2,5-diphenyl-1,3,4-oxadiazole molecules.…”

A synthesis of new alkynyl-derived 2,5-disubstituted 1,3,4oxadiazoles through palladium/copper-catalyzed Sonogashira crosscoupling between oxadiazole-substituted phenyl bromides and various arylacetylenes is described. Investigation of the absorption and emission spectra of the target compounds indicates emission profiles in the near-blue and blue region and high luminescence intensities. The presented approach is very convenient for the synthesis of luminescent small-molecules or precursors of other complex derivatives that are useful in the preparation of OLEDs as electron-transporting components.
