Construction of a hexameric Zn(II)-metallomacrocycle and its photo- and electroluminescence properties: [Zn-6(O-hexyl-3, 5-bis(2,2 ': 6 ',2 ''-terpyridine)phenol)(6)(BF4)12]

摘要

An O-hexyl-3,5-bis(terpyridine)phenol ligand has been synthesized and transformed into a hexagonal Zn(II)-metallomacrocycle by a facile self-assembly procedure capitalizing on terpyridine-Zn(II)-terpyridine connectivity. The structural composition was confirmed by NMR and mass spectral techniques; photo- and electroluminescence properties were also investigated. The OLED device shows green electroluminescent emmission at 515 nm with a maximum luminance of 39 cd (.) m(-2) and maximum efficiency of 0.16 cd (.) A(-1).
