Chiral or achiral ring compounds have the formula R1- (A1-Z1) m-A2-Q1-C * R ° X-CF3, wherein R1 is alkyl or perfluoroalkyl optionally interrupted by -O- and / or -CO- and / or -CO-O- and / or -CH = CH- and / or -CH halogen and / or -CHCN- and / or halogen ...
chiral or achiral cyclic compounds of formula (i): r1 - (a1 - a2 - (z1) and q2 (c * r u00b0x (z2) n - (a4) - r2, wherein r1 and r2 independently represent an alkyl group or perfluoroalkyl; 1 to 12 c atoms.also, in which one or two non adjacent ch2 groups or cf2 may...
Chiral or achiral ring compounds of formula (I) in which R1 is an alkyl or perfluoroalkyl group with 1-12 C atoms, in which one or two non-adjacent CH2? or CF2 groups may be replaced by O atoms and/or -CO- groups and/or -CO-O- groups and/or -CH=CH- groups and/or -CH halo...

Since the (643) surface is comprised of terraces with local (111) orientation which are separated by kinked monatomic steps, it is instructive to perform TPD experiments with these chiral compounds on the achiral Cu(111) surface. These experiments have given some insight into the adsorption sites...
A comparable single-chirality microemulsion based on the achiral oil ethyl acetate yielded, relative to diethyl tartrate, lower efficiency (78 300 vs. 91 600), higher resolution (1.99 vs. 1.83), and similar enantioselectivities. 展开 关键词: CE Chiral oil Chiral surfactant Dodecoxycarbonylvaline ...
The concept of host-guest chemistry is the fundamental basis of chiral molecular recognition which has opened the new way to discriminate the optically active molecules which are difficult to separate in the achiral environment [3]. The molecular recognition may be due to differences in values of ...
Amplification of chirality in self-assembling systems is usually denoted as the “sergeants-and-soldiers” effect30,31, referring to the ability of a few chiral units (the “sergeants”) to control a large number of achiral units (the “soldiers”). Since the pioneering work of Green et al...
