Abstract
![]()
The structures and magnetic properties of photoresponsive
magnets
can be controlled or fine-tuned by visible light irradiation, which
makes them appealing as candidates for ternary memory devices: photochromic
and photomagnetic at the same time. One of the strategies for photoresponsive
magnetic systems is the use of photochromic/photoswitchable molecules
coordinated to paramagnetic metal centers to indirectly influence
their magnetic properties. Herein, we present two erbium(III)-based
coordination systems: a trinuclear molecule {[ErIII(BHT)3]3(dtepy)2}.4C5H12 (1) and a 1D coordination chain {[ErIII(BHT)3(azopy)}n·2C5H12 (2), where the bridging photochromic
ligands belong to the class of diarylethenes: 1,2-bis((2-methyl-5-pyridyl)thie-3-yl)perfluorocyclopentene
(dtepy) and 4,4′-azopyridine (azopy), respectively (BHT = 2,6-di-tert-butyl-4-methylphenolate). Both compounds show slow
dynamics of magnetization, typical for single-molecule magnets (SMMs)
as revealed by alternating current (AC) magnetic susceptibility measurements.
The trinuclear compound 1 also shows an immediate color
change from yellow to dark blue in response to near-UV irradiation.
Such behavior is typical for the photoisomerization of the open form
of the ligand into its closed form. The color change can be reversed
by exposing the closed form to visible light. The chain-like compound 2, on the other hand, does not show significant signs of the
expected trans–cis photoisomerization
of the azopyridine in response to UV irradiation and does not appear
to show photoswitching behavior. Three-coordinate
[ErIII(BHT)3] single
ion magnets undergo ligand addition reaction in pentane to form linear
trinuclear photochromic nanomagnets where both functionalities persist.

Abstract
The complexes [Dy2(tta)6(H2SQ)] (Dy-H2SQ) and [Dy2(tta)6(Q)]·2CH2Cl2 (Dy-Q) (tta− = 2-thenoyltrifluoroacetonate) were obtained from the coordination reaction of the Dy(tta)3·2H2O units with the 2,2′-benzene-1,4-diylbis(6-hydroxy-4,7-di-tert-butyl-1,3-benzodithiol-2-ylium-5-olate ligand (H2SQ) and its oxidized form 2,2′-cyclohexa-2,5-diene-1,4-diylidenebis(4,7-di-tert-butyl-1,3-benzodithiole-5,6-dione (Q). The chemical oxidation of H2SQ in Q induced an increase in the coordination number from 7 to 8 around the DyIII ions and by consequence a modulation of the field-induced Single-Molecule Magnet behavior. Computational results rationalized the magnetic properties of each of the dinuclear complexes.
