Long lifetime phosphorescence and X-ray scintillation of chlorobismuthate hybrids incorporating ionic liquid cations

Abstract

Phosphorescence and X-ray scintillation are achieved for chlorobismuthate hybrids incorporating ionic liquid cations.

Tuning Organic Room‐Temperature Phosphorescence through the Confinement Effect of Inorganic Micro/Nanostructures

“…In addition, other organic constituents, including chiral dications, [ 54 ] aromatic carboxyl anions, [ 55 ] and ionic liquid cations, [ 56 ] were introduced into the inorganic metal halide skeleton to produce hybrid OIMHs with RTP. For example, Du and coworkers used two organic acids, terephthalic acid (TPA) and 1, 4‐phenylenediacetic acid (PLA), to react with PbBr 2 in alkaline NaOH aqueous solution to form two hybrid OIMHs (TPAPbBr and PLAPbBr, respectively) with organic and inorganic components linked by chemical bonds ( Figure ).…”

Crystalline‐Phase‐Recognition‐Induced Domino Phase Transition and Luminescence Switching for Advanced Information Encryption

“…Ionic liquid hybrid metal halides (ILMHs), constructed by the combination of various halometalate anions and ionic liquid cations,h ave received high attention in recent years due to their excellent photophysical properties and good processibility. [8][9][10][11][12] More importantly,t he flexible ionic liquid cation and abundant supramolecular interactions endow ILMHs multiple stable states with lower energy barrier, which is favorable for the SCSC transition accompanied by luminescence switching. [9] In 2019, our group reported the thermal-and moisture-induced SCSC transition between [Bzmim] 3 SbCl 6 and [Bzmim] 2 SbCl 5 @IL (Bzmim = 1-benzyl-3-methylimidazoli-um, IL = ionic liquid of [Bzmim]Cl) with triple-mode reversible luminescence switching for potential application in laser-printable rewritable luminescent paper.…”

Photophysical properties of ammonium, pyrrolidinium, piperidinium, imidazolium, and pyridinium as a guide to prepare ionic-organic hybrid materials

“…ILCs couple either with halometal [18][19][20] or hybrid organic inorganic perovskites (HOIPs) [12,21,22]. The presence of ILCs influences the packing density in the structure.…”

“…Thus, the ILCs structure will become an important consideration for applications as mentioned earlier. For example, Jin et al have shown that using ILCs with a longer alkyl chain length will result in a lower packing density and decrease the phosphorescence quantum yield [22]. The presence of ionic liquids can also induce the photoluminescence switching phenomenon.…”

“…1]. In addition, some of these ILCs have been used in the HOIP perovskites such as EMIM [22], BMIM [24], [25], piperidinium, pyridinium [20] and PBA [11]. The investigated properties included (1) the optical properties; UV-Vis absorption, fluorescence, and phosphorescence spectra; and (2) the electronic properties; frontier molecular orbital visualization and charge distribution.…”
