| Popis: | The present work introduces synthesis, structure and spectroscopic properties of novel water soluble dicationic binuclear Au(I) complex [Au2L2]2+ with bridge P,P-coordination, where L is cyclic PNNP ligand 1,5-bis(p-tolyl)−3,7-bis(pyridine-2-yl)−1,5-diaza-3,7-diphosphacyclooctane. Its ion-pairing with anionic hexarhenium cluster complexes ([{Re6S8}(OH)6]4– and [{Re6S8}(CN)6]4–) is represented herein as a reason for bottom-up design of supramolecular heterometallic assemblies with the enhanced cluster-centered luminescence and heterometallic colloids with high luminescence response to acidification in the range of pH 6.0-5.5. |
