Photoresponsive luminescent single-molecule magnets based on dysprosium-anthracene complexes: regulating the de-dimerization temperature of the photocycloaddition product by co-ligand.
Ontology highlight
ABSTRACT: Lanthanide-anthracene complexes that can undergo reversible photocycloaddition reaction are attractive for the development of photoresponsive luminescent single-molecule magnets (SMMs). However, how to regulate the de-dimerization temperature of in situ formed dianthracenes remains an open question. Here, we report two binuclear dysprosium-anthracene complexes [Dy2(SCN)4(L)2(depma)2(DEPP)2] (1) and [Dy2(SCN)4(LMe)2(depma)2(DEPP)2] (2), where L is 2,6-dimethoxyphenol, LMe is 4-methyl-2,6-dimethoxyphenol, depma is 9-diethyl-phosphonomethylanthracene, and DEPP is diethylpropylphosphonate. Both undergo single-crystal-to-single-crystal (SC-SC) photocycloaddi
