Room-temperature phosphorescence from organic aggregates

Nature Reviews Materials, 2020
Triplet excitons in organic molecules underscore a variety of processes and technologies as a result of their long lifetime and spin multiplicity. Organic phosphorescence, which originates from triplet excitons, has potential for the development of a new generation of organic optoelectronic materials and biomedical agents.

Supramolecular Purely Organic Room-Temperature Phosphorescence

Accounts of Chemical Research, 2021
In recent years, purely organic room-temperature phosphorescence (RTP) has aroused wide concern and promotes the development of the supramolecular phosphorescence. Different from organic crystallization, polymerization, or matrix rigidification, supramolecular strategy mainly takes advantage of the synergy between supramolecular co-assembly and strong ...

Room Temperature Phosphorescence of 5,6-Benzoquinoline

Methods and Applications in Fluorescence, 2023
Abstract Phosphorescence emission of 5,6-Benzoquinoline embedded in poly (vinyl alcohol) film has been studied at room temperature. A strong green long-lived emission was observed in films doped with 5,6-Benzoquinoline while illuminated on a UV plate. A broad phosphorescence emission spectrum is centered at about 500 nm.

Ultralong Room‐Temperature Phosphorescence from Boric Acid

Angewandte Chemie International Edition, 2021
AbstractFor a long time, phosphors with long‐lived emission are dominated by rare earth/transition metal ion‐doped sulfides and oxides. Recently, organic materials capable of emitting long‐lived room‐temperature phosphorescence (RTP) are reported, carbon skeletons are almost the exclusive structural feature of the conjugated luminophores.

Stimuli‐Responsive Polymers with Room‐Temperature Phosphorescence

Chemistry – A European Journal, 2022
AbstractTaking advantages of the impressing behaviors of room‐temperature phosphorescence (RTP), the explorations in RTP materials are not only limited to efficient emission and ultralong lifetime of phosphorescence. The discovery and creation of stimuli‐responsive properties have become the major pursuit, which will lay a solid foundation for future ...

Molecular Persistent Room-Temperature Phosphorescence from Tetraarylaminoboranes

Inorganic Chemistry, 2023
Herein, we report the synthesis, molecular structure, and optical features of tetrarylaminoboranes 1 (Mes2B-N(Ph)(C10H7)) and 2 (Mes2B-N(Ph)(C14H9)). In the solution state, 1 shows aggregation-induced emission enhancement and color switching, while 2 displays emission color switching and aggregation-caused quenching. At 77 K, frozen solutions of 1 show
