Mesogenic behavior of a 6-oxoverdazyl diradical: towards organic high-spin liquid crystals

“…Liquid crystals provide a viable and attractive alternative for obtaining organized functional films of molecular materials. 15–17 Thus, paramagnetic films could be obtained from liquid crystalline radicals, which during the past two decades have become well exemplified in the literature. 18–20 Although some mesogenic bi- and tri-radicals have been reported, 21–27 none of them has coupled spins and exhibits a high spin ground state.…”

Synthesis and characterization of azo liquid crystal compounds based on 5H-Thiazolo [3,4-b][1,3,4]thiadiazole unit

“…Calamitic liquid crystals (LCs) are widely used in LC displays and optical systems because of the suitability of their anisotropic properties [1][2][3] . In the case of liquid crystals, the azo group is the most widely employed photochromic unit [4][5][6][7][8][9] . This is mainly due to its linearity, diversity in preparation 10 , speed and stability of isomerization 11 .…”
