Luminescent metallogels of platinum(<scp>ii</scp>) terpyridyl complexes: interplay of metal⋯metal, π–π and hydrophobic–hydrophobic interactions on gel formation
A series of platinum(II) terpyridyl complexes has been demonstrated to show gelation properties driven by Pt...Pt and pi-pi interactions in addition to hydrophobic-hydrophobic interactions; counter-anions have been found to affect strongly the colour of the metallogel.
