The synthesis of C 3 ‐symmetric chromophores ( 2 – 4 , 9 , 10 , 14 ) with acceptor‐substituted catecholato ligands and different central metal atoms (Si, Al, Ti) is described. These complexes might serve as octupolar chromophores with first‐order nonlinear optical properties. UV/Vis spectroscopic investigations show a red‐shift of the lowest‐energy charge‐transfer band on going from Si IV , Al III to Ti IV complexes, dependent on the increasing ionic character of the M–O bond.
