The locations of triphenylamine and tetraphenylethene on a cyclohexyl ring define a luminogen as an AIEgen or a DSEgen

Abstract

There is a growing interest in achieving dual-state emission (DSE) in the luminescent material community due to the strong application potential in both dilute solutions and the solid state. The...

Gallic‐Acid‐Modified Naphthalimide Containing Disulfide Bond as Reduction‐Responsive Supramolecular Organogelator

“…When turned into aggregate suspensions (0.1 mM), the main peaks of both compounds in EtOAc and DMSO redshifted to a longer wavelength (Figure S4). Particularly, levelled‐off tail absorptions in DMSO were observed due to the formation of aggregates [39] . The formation of aggregates also led to significant quenching in fluorescence (Figure S5).…”

“…Particularly, levelled-off tail absorptions in DMSO were observed due to the formation of aggregates. [39] The formation of aggregates also led to significant quenching in fluorescence (Figure S5). The absorption peaks of GSSN in the gel state were further redshifted to a position of about 350 nm in both DMSO and EtOAc (Figure 4a and 4b).…”

Fusing rigid planar units to engineer twisting molecules as dual-state emitters

“…14 The applications of the two types of luminogens are restricted to their respective phases. The design and development of luminogens with dual-state emission, referred to as DSEgens, 15 can achieve intense emission in both the solution and solid phases that are unattainable by the ACQ and AIE molecules and are anticipated to bridge the gap. 16 Thanks to the unique DSE characteristic, DSEgens can be applied in dual phases.…”

D–A–D structured triphenylamine fluorophore with bright dual-state emission for reversible mechanofluorochromism and trace water detection

“…Recently, there is growing interest in developing dual-state emission (DSE) materials that show strong fluorescence in both dilute solutions and the solid state (nanoparticles, solid powders, crystals, and thin film), to bridge the gap between ACQ and AIE materials. [20][21][22][23][24][25][26][27][28] Nevertheless, available DSE materials are still very rare, and the design principle is not well understood. An understanding of the synthesis and the working mechanisms of new DSE materials is essential to facilitate widespread applications.…”
