Synthesis and characterisation of rod-like metallomesogens of Mn(I) based on Schiff base ligands
摘要:
Complexation of liquid-crystalline imines to Mn(I) carbonyls led to liquid-crystalline complexes when the ligated imine was sufficiently anisotropic. Thus, all two-ring and some three-ring imine ligands were not mesomorphic when complexed, while some three-ring and all four-ring imines led to mesomorphic complexes. As expected, complexation disturbed the anisotropy of the ligands and led to a lowering of clearing points and a suppression of smectic phase formation. (C) 1998 Elsevier Science S.A.
