## Abstract The synthesis, self‐assembly, and gelation ability of a series of organogelators based on perylene bisimide (PBI) dyes containing amide groups at imide positions are reported. The synergetic effect of intermolecular hydrogen bonding among the amide functionalities and π–π stacking betwe
The formation of helicates between silver(i) and a series of enantiopure ligands (L 1 ± L 4 ) containing the bis(oxazolyl) pyridine unit has been studied in solution. Ligands L 1 and L 2 form [AgL 2 ] and double-helical [Ag 2 L 2 ] 2 . L 3 and L 4 show more complicated behaviour, forming [AgL 2 ] ,
