The invention provides biomolecule binding ligands, collections of biomolecule binding ligands, and their use in the purification of biological mixtures and in the identification of ligands having an affinity for a substance. The ligand is a compound of formula (III) or a compound of formula (IV): wherein for compounds of formula (I) one of R

alkyl, optionally substituted C
3-20
heterocyclyl or optionally substituted C
5-20
aryl, and R
