Photo-induced variation of magnetism in coordination polymers with ligand-based electron transfer

Abstract

Photo-induced variation of magnetism from ligand-based electron transfer have been extensively studied because of their potential applications in magneto-optical memory devices, light-responsive switches, and high-density information storage materials. In this...

Photoresponsive Magnetic Relaxation Behavior of a Highly Stable π···π Interaction-Stacked Framework Based on a DyIII Single-Ion Magnet

“…It features noninvasiveness, high controllability, fast response, and high temporal and spatial resolution, 17 and thus may be able to control the magnetic behaviors in a remote and real-time way, realizing the intellectualization of SIMs. 16,18 induced spin transitions, several photoresponsive transition metal SIMs have been obtained. 19−21 Such spin transition, however, is difficult to be implemented in Ln-SIMs due to the special 4f shells of Ln ions.…”

“…Meanwhile, the establishment of stimuli responsiveness in SIMs has also drawn increasing concerns, as this would greatly extend the applications of SIMs in various fields. − Light is particularly attracting as a tool for this goal. It features noninvasiveness, high controllability, fast response, and high temporal and spatial resolution, and thus may be able to control the magnetic behaviors in a remote and real-time way, realizing the intellectualization of SIMs. , Utilizing photo-induced spin transitions, several photoresponsive transition metal SIMs have been obtained. − Such spin transition, however, is difficult to be implemented in Ln-SIMs due to the special 4f shells of Ln ions.…”

Modulation of magnetization dynamics of an Er(iii) coordination polymer by the conversion of a ligand to a radical using UV light

“…Light-induced substance conversion is a way to produce radical-based compounds, which provides a platform for investigating the photo-induced variation of magnetic properties (PVM) of molecular materials [1][2][3][4] and develops new photomagnetic materials. [5][6][7][8][9] However, such a conversion is highly challenging due to the unstable light-generated radicals, and the influence of the radicals on the magnetic properties is generally complex and difficult to quantify.…”

Stable bifunctional ZnII-based sensor toward acetylacetone and l-histidine via a fluorescence red shift and turn-on effect

“…In comparison with traditional detection methods, fluorescence sensing has attracted wide attention due to its significant advantages, including high sensitivity and selectivity, easy operation and so on. 1 Coordination polymers (CPs) or metal–organic frameworks (MOFs, also known as porous coordination polymers) are constructed through metal ions or clusters with organic ligands, which have aroused wide attention owing to their novel structures and potential applications in chemical sensors, 2–4 proton conduction, 5 catalysis, 6 magnetism, 7 gas adsorption and separation, 8 drug delivery 9 and so on. Thereinto, CP-based fluorescent sensors have the superiorities of low cost, short response time, and high selectivity and sensitivity .…”
