5,6-Difluorobenzofuran: a new core for the design of liquid crystal compound with large dielectric anisotropy and broad nematic range
New liquid crystal compounds with 5,6-difluorobenzofuran core were synthesised by palladium catalysed coupling and ring-closing reaction. Their structures were identified using(1)HNMR,(CNMR)-C-13 and MS. Thermo analysis show that these compounds exhibit a broad nematic range and high clearing points. Physical property test revealed that the dielectric anisotropies of these compounds are about 11 similar to 17, which is twice of that of the 3, 4-difluorinated benzene analogues. DFT calculation results show that the 5, 6-difluorobenzofuran-based compounds have much larger polarisation and dipole moments compared with the common 3,4-difluorobenzene compounds, which leads to a significant increase in dielectric anisotropy and birefringence. As a new fluorinated building block, 5, 6-difluorobenzofuran shows a good prospect for display device. [GRAPHICS] .
