Design of an extremely high birefringence nematic liquid crystal based on a dinaphthyl-diacetylene mesogen

We designed dinaphthyl-diacetylene-based nematic liquid crystals with alkoxy tails (DNDA-OCm) and evaluated their birefringence (Δn). Actual measurements of pure target compounds showed that DNDA-OC2 had the highest value of 0.62 at 550 nm at Tc + 10 °C.

Micelle-Mediated Trimerization of Ynals to Orthogonally Substituted 4H-Pyrans in Water: Downstream Rearrangement to Bioactive 2,8-dioxabicyclo[3.3.1]nona-3,6-diene Frameworks

An efficient trimerization of ynals to diversely substituted 4H-pyran constructs has been executed in water, under ambient conditions employing micellar catalysis. The method is in agreement with the ideas of green and sustainable chemistry. The locus of the micellar reaction site has been probed through proton NMR studies. A general acid-mediated downstream rearrangement of the derived 4H-pyrans to interesting 2,8-dioxabicyclo[3.3.1]nona-3,6-dienes has been observed.
