Abstract:
A luminescent nonanuclear terbium(III) hydroxo cluster, Tb(9)(Hesa)(16)(mu-OH)(10)(NO(3)) (Hesa: hexyl salicylate), stabilized by unique two-way phenyl ring interactions, pi-pi stackings (d = 3.482-3.599 A) and C-H-pi interactions (d = 2.75-3.03 A) between adjacent pairs of salicylates, was structurally characterized based on X-ray analysis, and the favourable absorption change and efficient photoluminescent characteristic were rationalized as being due to J-type pi-pi stackings, which are dramatically enhanced by hexyl groups in hexyl salicylate ligands.
