TL;DR: A type of thioether RTP molecules that shows RTP "turn-on" when volatile acid vapors such as HCl are in contact is reported, revealing that a charge-transfer character in the phosphorescence state is crucial.

TL;DR: In this article, a series of fluorescent naphthalimides, which did not originally show observable phosphorescence in solution, as aggregates, in polymer films, or in any other tested host material, including heavy-atom matrices at cryogenic temperatures, can now efficiently produce ultralong RTP (ϕ=0.17, τ=243 ms) in phthalimide hosts.

TL;DR: A working strategy is reported to construct a donor-sp3-acceptor type of luminogen which exhibits aggregation-induced emission (AIE) while the donors' counterpart structure exhibits non-emissive solid state, providing a new insight into the design of multi-component, solid-state RTP materials from organic molecular systems.

TL;DR: It is shown that ACQ could be effectively circumvented by constructing an aromatic system with a methylene-linker, where the system exhibits typical aggregation-induced emission (AIE) with long-lived room-temperature phosphorescence, since the tetrahedral structure in the solid state may significantly reduce strong intermolecular interactions contributing to ACQ.

TL;DR: In this paper , a guest/host system (NL/DCB) with concurrently high RTP quantum yield of >20% and ultralong lifetime of >760 ms (duration ∼10 s) at ambient conditions is presented.
