Sk. Collins et al., Synthesis of novel acetylenic cyclophanes with helical chirality: Potential new structures for liquid crystals, ORG LETT, 2(20), 2000, pp. 3189-3192
[GRAPHICS]
The synthesis of a series of novel acetylenic cyclophanes is described. X-r
ay crystallographic analysis of the core structure revealed a twisted confo
rmation with helical chirality. Preliminary results suggest that these cycl
ophanes, with appropriate functionality, have the potential to act as uniqu
e liquid crystalline materials.
