WebChirotopicity is a local geometrythat produces chirality. Not only are the atoms in a chiral environmentsaid to be chirotopic, but the spaces around atoms in a chiral environmentare also considered chirotopic. Atoms (or spaces) in an achiral environmentare said to be achirotopic. [Pg.98] WebSignificant influences of the backbone structure were identified. In particular, higher stereoregularity increased stability of the crystalline phase, and moreover, the liquid crystalline phases of isotactic polyketone was endowed with chirality due to the chirotopic center in the backbone.
