Abstract:
Two novel bis-(beta-diketonate) ligands, 1,1 '-(anthracene-1,8-diyl)bis(butane-1,3-dione) (H2L1), 1,1 '-(anthracene1,5-diyl)bis(4,4,4-trifluorobutane-1,3-dione) (H2L2) have been designed and synthesized for self-assembly of the luminescent supramolecular coordination compounds with transition and lanthanide metals. Two neutral dinuclear supramolecular assemblies Cu(II)-bis-beta-diketonate macrocyclic complex [Cu2(L1)2](CH3OH)2 (1.2CH3OH) and Eu(III) bis-beta-diketonate triple-stranded complex [Eu2(L2)3](CH3OH)4 (2.4CH3OH) have been characterized by various spectroscopic techniques. Their photophysical properties were further investigated. Xray single crystal structural analysis revealed that complex 1.2CH3OH adopts a 1D chain arrangement which is constructed with a pitch of 1.951 angstrom through intermolecular hydrogen bonds along the b axis. The slightly distorted parallelogram of 1 is a neutral [M2L2]-type macrocycle with a size of 5.40 angstrom x 8.40 angstrom. The triple-stranded helicate CPK (Corey-Pauling-Koltun) diagram was calculated using Scigress 2.6 program.
