A Dual‐Stimuli‐Responsive Coordination Network Featuring Reversible Wide‐Range Luminescence‐Tuning Behavior

Abstract

We herein report an ew coordination network that deforms in as mooth and reversible manner under either thermal or pressure stimulation. Concomitantly,t he organic fluorophores coordinatively bound to the channel in aface-toface arrangement respond to this structural deformation by finely adapting their conformation and arrangement. As ar esult, the material exhibits ar emarkable dual-stimuliresponsive luminescence shift across almost the entire visible region:T he emission color of the crystal gradually changes from cyan to green upon heating and then to red upon pressure compression. Furthermore,each stage exhibits alinear dependence of both the emission maximum and intensity on the stimulus and is fully reversible.

Heat Engine Drives Transport of an FeII4L4 Cage and Cargo

“…[29] A temperature swing is among the most attractive stimuli, as it is easily reversible and leaves no chemical residue, in contrast with the addition of salts, acids, or bases. Thermal stimulation has been reported to trigger the reversible structural transformation of coordination complexes [30][31][32] and to open a switchable platinum-based molecular lock. [33] Here, we report a thermoresponsive Fe II 4 L 4 coordination cage 1 (Figure 1), whose exterior is grafted with 12 pendant 1-methylimidazole PEG 1000 (PEG 1000 (mim) + ) chains.…”

Reversible light-driven magnetic switching of salen cobalt complex

“…As shown in Figure 3, SCO usually becomes more gradual and incomplete when the sample either is precipitated as a powder or a physically ground crystalline complex [36,37]. Powder samples of o-1-Co(II) undergo abrupt, complete and hysteretic SCO, which is possibly due to the crystallographic phase change and the associated intermolecular interaction change [38,39]. o-1-Co (II) possesses photoactive anti-parallel (ap-) configuration and photoinactive parallel (p-) configuration [40][41][42][43][44][45][46][47].…”

Recent Progress of Nanoscale Metal‐Organic Frameworks in Synthesis and Battery Applications

“…Metal‐organic frameworks (MOFs) have been investigated in many fields, [ 1 ] and many MOFs with diverse structures have been synthesized and characterized. [ 2–8 ] Because of their well‐organized structures, enormous surface areas and pore volumes, well‐defined pore size distributions, and easily‐decorated channels, MOFs have become promising candidates in many applications, including gas storage and separation, [ 9,10 ] luminescence, [ 11–13 ] thin films, [ 14,15 ] proton conduction, [ 16,17 ] catalysis, [ 18 ] drug delivery, [ 19,20 ] and energy storage and conversion. [ 21–26 ] However, MOFs normally form large crystals, which greatly weaken physical and chemical processes on their surfaces and restrict their applications.…”
