A multi-stimuli-responsive CsPbBr₃@PL-MOF functional anti-counterfeiting material

Abstract

A new composite material CsPbBr3@HPU-22 was prepared by using {[Zn2(ADDA)2(DMF)(H2O)2]·(DMF)}n (HPU-22) as a carrier to encapsulate CsPbBr3 in channels. The obtained composite material has high sensitivity to water. Under the...

Acid–base responsive multifunctional poly(formyl sulfide)s through a facile catalyst-free click polymerization of aldehyde-activated internal diynes and dithiols

“…So far, many acid–base responsive luminescent materials have been explored to achieve this purpose, including, but not limited to, lanthanide complex, 13 inorganic nanocluster, 14 metal–organic framework, 15 hydrogel, 16 quantum dot, 17 molecular and polymer materials. 18–22 Thereinto, major efforts are centered on low-mass fluorophores; polymer-based counterparts, in contrast, show obvious technical superiority, such as excellent processability, facile modification and signal amplification.…”
