Pyrene-based aggregation-induced emission luminogens (AIEgens) with less colour migration for anti-counterfeiting applications

Abstract

A series of pyrene-based AIEgens have been employed in the preparation of fluorescent inks with less colour migration for anti-counterfeiting applications over the ultra-low to high concentration range and avoids the ACQ effect.

Pyrene-Based AIE Active Materials for Bioimaging and Theranostics Applications

“…Apart from the demonstrated AIE-based bioimaging utilities, many studies of the pyrene derivatives focused only on the analyte tuned cellular imaging but not the AIE effect [ 102 , 103 , 104 , 105 , 106 ]. On the other hand, some studies of the pyrene-based moieties have described their AIE properties towards diverse optoelectronic applications [ 107 , 108 , 109 , 110 , 111 ] and their potential as the bioimaging candidates in the future.…”

Chiral Luminescent Liquid Crystal with Multi‐State‐Reversibility: Breakthrough in Advanced Anti‐Counterfeiting Materials

“…[18,19] Therein, the single-mode (photoluminescence or reflective color) with single-state (only one reflective color or fluorescence) is the most widely used, possessing the advantages of a broad range of materials sources, easy operation, and observation. [20][21][22] Typically, the traditional single-state photoluminescence generally emits a single-color fluorescence excited by a single light source. [23,24] Moreover, single-mode with multi-states fluorescence (different colors of fluorescence) has also been developed by mixing several organic or inorganic materials.…”

Systematic photophysical, thermal and electrochemical analysis of a series of phenothiazine cored conjugated aromatic unit appended D–π–A based high-solid state luminescent materials: their applications in reversible mechanofluorochromic and volatile acid sensing

“…5 They can also be stimulated by mechanical agitation and exhibit mechanofluorochromic (MFC) behavior. [6][7][8][9][10] Numerous materials with MFC characteristics such as organometallic compounds and typical organic dyes have been established. [11][12][13][14][15] Compared to metal-based MFC materials, which suffer from commercialization challenges owing to the high price and the toxicity of noble metals, organic compounds turn out to be favorable alternatives due to their facile synthetic strategy.…”
