“…Its solid-state Φ PL,s reached 16.9%, comparable to that of the dilute solution. Obviously, [2]CTPE presented dual-state emission 26 properties, which makes it different from conventional aggregation-caused quenching (ACQ) compounds and classical AIEgens. In addition, its fluorescence lifetime was determined to be 13.05 ns, much longer than those of the other TPE macrocycle compounds (= 0.89 ns–1.70 ns) (Fig.…”

“…We consider this a nascent topic that will attract more attention shortly. 4 The specific solid form of a compound (single crystal, polycrystalline solid, amorphous solid, or thin films) heavily influences the resulting solid state emission. Consequently, efforts were paid to identify the solid forms used for all fluorescence measurements when the authors provided the information.…”

Organic luminescent materials have attracted significant attention in the past few years due to their fascinating photophysical properties. Implementing these emissive organic compounds is now being actively pursued in many applications in solution (i.e., sensors, bioimaging) or their solid forms (i.e., optoelectronic devices or data encryption). Despite significant advances in the development of emissive compounds, there has been an increasing quest in the past decade for materials where the emission is preserved in both states, dual-state emission (DSE). These compounds are expected to detonate a myriad of applications in the future. On this nascent topic, this work addresses several factors that increase the probability of obtaining the dual-state emission property based on the precedent reports showing this phenomenon. Therefore, this review identifies and organizes the different structural characteristics useful to obtain these compounds. In addition, it has been devised to motivate the discussion in the materials science community and hopefully incentivize the efforts of many research groups around the world toward the synthesis of new dual-state emitters.

“…Specific to the solid-state emission, DSEgens adopt a strategy similar to AIEgens, which is to suppress or even interdict nonradiative decays from the photoexcited state by introducing a π-conjugate with a twisted conformation into the molecules. 18 The presence of a π-conjugate ensures sufficient electronic transition, while the twisting conformation prevents the molecules from forming nonluminescent species in the aggregated state ( e.g. , excimers).…”
