(trifluoromethane)sulfonimide lithium. The ionic liquid made of methylimidazolium cation in combination with PF6anion showed the best fire behavior with a LOI as high as 24% (vs. 20%, untreated cotton) and decreased THR (by about 38% with respect to the neat fabric), as assessed by micro...
The blue phases are observed in highly chiral liquid crystalline compositions that nascently organize into a three-dimensional, crystalline nanostructure. The periodicity of the unit cell lattice spacing is on the order of the wavelength of visible light
Remarkably, benzoyl chloride when treated with 2-aminebenzenethiol (12) under similar reaction condition of DMU:TA and DMU:CA delivered the corresponding product 14a in 96% and 94% yield respectively, in much shorter times (Table 2, entry 7). Additionally, we noticed the DMU:TA medium ...
