Effect of solvation on the aggregation-induced luminescence of tetraphenylethene derivatives

Abstract

The compound TPE-(α-NH2)2 was synthesized. In the water-THF mixture (fw = 90 %), a relatively stable non-emission aggregate with ultrasound-responsive emission property could be obtained.It was found that the preferential...

Fluorinated Tetraarylethenes: Universal Tags for the Synthesis of Solid State Luminogens

“…When 1 was dissolved in THF, no AIE was observed when an excess of water was added [24] . The special role of THF for the AIE behavior of tetrarylethenes was also noted by Bai and co‐workers [25] …”

Multiresponsive tetrarylethylene-based fluorescent dye with multicoloreded changes: AIEE properties, acidichromism, Al3+ recognition, and applications

“…The nonplanar structure that constitutes the propeller type ensured its strong fluorescence emission in the aggregation and solid state due to the restriction of intramolecular motions (RIMs). [14][15][16][17][18][19][20] For example, Wang et al explored a tetraphenylethene AIE fluorescent sensor, which is capable of visually distinguishing Th 4+ between lanthanide, transition metal, and alkali metal under UV light. 21 Lin et al developed a TPE-BSA sensor with good AIE features for uranyl ion detection by incorporating the salt benzene moiety into the active tetraphenylethene part of AIE.…”

Improved quantum yield in geometrically constrained tetraphenylethylene-based metal–organic frameworks

“…To optimize QY in a solvatochromic MOF, we focused on linker-based emissions using a tetraphenylethylene (TPE) linker. 15–18 Based on previous literature reports using TPE-based ligands, 19–25 we hypothesized that the incorporation of a novel AIE molecule into a conformationally restricted matrix improves quantum yields.…”

“…To optimize QY in a solvatochromic MOF, we focused on linker-based emissions using a tetraphenylethylene (TPE) linker. [15][16][17][18] Based on previous literature reports using TPEbased ligands, [19][20][21][22][23][24][25] Indeed, the matrix coordination-induced emission effect (MCIE) was demonstrated by Dincă and coworkers in 2011 using a TPE-based ligand and Zn metal. 21 The fluorescence quantum yield in that report only increased from 0.8% to 1.8% between the free ligand and MOF; however, upon installation of an alkynyl unit between phenyl rings and a change to meta-substituted carboxylate ligands, they were able to demonstrate fluorescence quantum yields of 9% for the free linker and 35% when the linker was incorporated into a MOF.…”
