Helix-mediated over 1 nm-range chirality recognition by ligand-to-ligand interactions of dinuclear helicates.

ABSTRACT: Long-range chirality recognition between the two chiral guest ligands can be tuned based on the helix distances (d _Ln-Ln = 11.5 and 14.0 Å) of bis-diketonate bridged dinuclear lanthanide complexes (2Th and 3Th, respectively) used as mediators. Both 2Th and 3Th form one-dimensional (1D) helical structures upon terminal binding of two chiral guest co-ligands (L ^R or L ^S ). Long-range chiral self-recognition is achieved in self-assembly of 2Th with L ^R and L ^S to preferentially form homochiral assemblies, 2Th-L ^R ·L ^R and 2Th-L ^S ·L ^S , whereas there is no direct molecular interaction
