摘要：
A series of luminescent L-valine modified alkynyl-based cyclometalated gold(III) complexes are synthesized and characterized. Through a balance of pi-pi stacking, hydrogen bonding and hydrophobic-hydrophobic interactions, organogelation of the gold(III) complexes is achieved in DMSO. The gelation properties of the complexes have been studied using scanning electron microscopy, transmission electron microscopy, X-ray powder diffraction, variable-temperature NMR, IR, UV-vis absorption and emission spectroscopy.
