✦ Synopsis

The rigid rod oligo-p-phenylene type dicatechol ligands 1-3-H 4 form dinuclear triple-stranded helicates M 4 [(1-3) 3 Ti 2 ] in the presence of appropriate counterions (M = Li, Na, K, or NH 4 ). Studies on the self-recognition ability of the ligands show that self-recognition takes place if mixtures of ligands with significantly different sizes (1/2) are used in coordination studies, or if ligands are used which do not match for
