    • The instant invention relates to a composition comprising a) an organic material which is susceptible to oxidative, thermal or light-induced degra- dation, and b) at least one compound of the formula (I) wherein the general symbols are as defined in claim 1; especially wherein at least one of the radicals R 2 , R 3 or R 4 is is -CH 2 -CH(CH 3 )-S(O) p -R 12 , -CH 2 -CH 2 -CH 2 -S(O) p -R 12 , -CH 2 -CH(R 11 )-CH 2 -R 12 or -CH 2 -CH=CH-R 12 , R 11 is hydrogen or halogen, R 12 is a monovalent perfluorinated alkyl or alkenyl, linear or branched organic radical having four to twenty fully fluorinated carbon atoms; or -CH 2 CH 2 (CF 2 ) m CF 3 , m is 3 to 12, and p is 0, 1 or 2. The compounds of the formula I are useful as reducers of surface energy for organic mat- erials, for example synthetic polymer. Polymers with such a reduced surface energy possess an "easy-to-clean", "self-cleaning" "antisoiling", "soil-release" "antigraffiti", "oil resistance", "solvent resistance", "chemical resistance", "self lubricating", "scratch resistance", "low moi- sture absorption", "dirt pickup resistance", "slip properties" and "hydrophobic surface"; and anti-adhesion properties against proteins and against microorganism such as for example bacteria, fungi and algae.

    • Conventional compounds exhibiting a negative dielectric constant anisotropy although exhibiting a negative dielectric constant anisotropy of relatively large numeric value are not appropriate in the balance of properties as a liquid crystal material, for example, having a low clear point or a large viscosity. Thus, it is intended to provide a liquid crystal compound not only exhibiting a negative dielectric constant anisotropy but also ensuring excellent property balance including relatively high clear point, relatively low viscosity, appropriate optical anisotropy, excellent compatibility with another liquid crystal compound, etc. There is provided a compound of the formula (1) or (2). In the formulae, each of Ra and Rb is hydrogen or C 1 -C 20 alkyl; each of A 1 , A 11 , A 12 , A 2 , A 21 and A 22 is a cyclic group; each of Y, W, Z 11 , Z 12 , Z 2 , Z 21 and Z 22 is a bond group; and each of j, k, m, n, p and q is 0 or 1 with the proviso that the sum thereof is 1 to 3.
    • 在具有相对较大数值的负介电常数各向异性的情况下,表现出负介电常数各向异性的常规化合物在作为液晶材料的性能的平衡中是不合适的,例如具有低透明点或较大粘度。 因此,本发明提供一种不仅具有负介电常数各向异性的液晶化合物,而且还具有包括相对较高的透明点,相对低的粘度,适当的光学各向异性,与另一种液晶化合物的优异的相容性等优异的性能平衡。 提供式(1)或(2)的化合物。 在该式中,R a和R b各自为氢或C 1 -C 20烷基; A 1,A 11,A 12,A 2,A 12,...,SUP 11中的每一个 >和A 22是环状基团; Y,W,Z 11,Z 12,Z 2,Z 21和Z 12中的每一个, 22 是一个键组; 并且j,k,m,n,p和q各自为0或1,条件是其总和为1至3。
