A reversible room temperature phosphorescence/delayed fluorescence switch trigged by solvent exchange in a Ca-based coordination polymer

Abstract

Stimulus-responsive luminescent materials have attracted considerable attention owing to their intensive applications in diverse fields. However, most of the reported materials are based on short-lived luminescence, while those based on...

Two new Cd-based metal–organic frameworks for afterglow detection of Fe3+ and NH3

“…Our group has recently focused on the study of inorganic–organic hybrid afterglow materials. 44,45 Herein, H 2 L (H 2 L = 4-(5,7-dioxo-5,7-dihydroimidazo[4,5- f ]isoindol-6(1 H )-yl)benzoic acid) with RTP and abundant coordination sites was selected as the ligand. Through different bindings of ligands to Cd 2+ ions, [Cd(L)(DMSO) 2 ] ( 1 ) with a two-dimensional (2D) structure and [CdL(H 2 O)(DMF) 0.5 (DMSO) 0.5 ]·DMF ( 2 ) featuring an intriguing 3D interpenetrated framework with rhombus channels (∼10 × 10 Å 2 ) were successfully synthesized.…”

Side-Chain Engineering for Modulating the Mechanical and Thermosalient Behavior of Elastic Crystals of Triple-Helix Coordination Polymers

“…Stimuli-responsive crystalline coordination polymers (CPs) that respond to environmental changes in temperature, 1−3 pressure, 4,5 light, 6−8 and guest molecules 9,10 show promising applications in a wide range of fields. 11−13 Besides responsiveness in the form of changes in physicochemical properties at the microscopic level such as phase transitions, 14 discoloration, 15 luminescence, 16,17 etc., emergent research activities have contributed to the understanding of the macroscopic mechanical response of crystalline CP materials under stimuli such as heat, pressure, and light. 1,2,4,18−31 Among such a class of mechanically responsive CPs, those with multiple mechanical responsiveness that can mechanically respond to two or more kinds of external signals are more desirable.…”
