Abstract | A series of platinum(II) terpyridine complexes with L-valine-modified alkynyl ligands has been synthesized. A complex with an unsubstituted terpyridine and one valine unit on the alkynyl is shown to be capable of gel formation, which is in sharp contrast to the gelation properties of the corresponding organic counterparts. Upon sol-gel transition, a drastic color change from yellow to red is observed, which is indicative of the involvement of PtPt interactions. Through the concentration- and temperature-dependent UV/Vis absorption, emission, circular dichroism, and (1) H NMR studies, the contribution of hydrogen bonding, PtPt and pi-pi stacking interactions as driving forces for gelation have been established, and the importance of maintaining a delicate balance between different intermolecular forces has also been illustrated. |
