Synthesis of unsaturated appended naphthalene macrocyclic ligands as chemosensor / Siti Nurwajihah Mohd Salleh

Macrocyclic ligand is defined as cyclic molecules that contain of heteroatoms and capable to bind substrates. Six new macrocyclic ligands were synthesized by the reaction of l,2-bis(2-carboxyaldehyde phenoxy)butane and various diamines. The macrocyclic ligands were synthesized involving two steps. T...
