Abstract

Abstract: Supramolecular gels prepared from low‐molecular‐weight gelators have been extensively explored. However, the exploitation of discrete or polymeric metal complexes as gelators is a relatively recent trend. The synthesis of self‐assembled coordination complexes from palladium(II) and selected ligands is well established, but the potential of these complexes as gelators is a less explored treasure. Herein we focus on the gelation abilities of some self‐assembled palladium(II) complexes and the resulting unique properties. First, discrete complexes with PdL, PdL2, Pd2 L, Pd2 L2, Pd2 L4, and Pd3 L6 compositions are discussed. Second, gelation behavior promoted by coordination‐polymer‐like gelators formed in situ is explored. These gel samples have been employed in catalysis and the uptake of organic and dye molecules from the solution and gas phases. It is concluded that untapped unique properties can be realized by further exploration of designer palladium(II) complexes. Abstract : Does it gel? The gelation abilities of some self‐assembled palladium(II) complexes and the unique properties of the resulting gels are reviewed. Discrete PdL, PdL2, Pd2 L, Pd2 L2, Pd2 L4, and Pd3 L6 complexes as gelators and gelation promoted by coordination‐polymer‐like gelators formed in situ are described (see figure). Untapped unique properties can be realized by further exploration of new designer palladium(II) complexes as gelators.
