Modulating Room-Temperature Phosphorescence-To-Phosphorescence Mechanochromism by Halogen Exchange

Frontiers in Chemistry, 2022
Modulating the stimulus-responsiveness of a luminescent crystal is challenging owing to the complex interdependent nature of its controlling factors, such as molecular structure, molecular conformation, crystal packing, optical properties, and ...

A direct observation of up-converted room-temperature phosphorescence in an anti-Kasha dopant-matrix system

Nature Communications, 2023
The emission maximum of phosphorescence is normally larger than that of fluorescence. Here, authors report up-converted room-temperature phosphorescence materials that emit from higher-lying triplet states with 3n-π* characters and large phosphorescence ...

Photo-thermo-induced room-temperature phosphorescence through solid-state molecular motion

Nature Communications, 2022
The development of non-invasive, rapid responsive phosphorescence is highly desirable but has rarely been described. Herein, the authors designed and prepare a series of molecular rotors containing a room temperature phosphorescence active triazine core ...

A gated strategy stabilizes room‐temperature phosphorescence

Aggregate, 2023
Room‐temperature phosphorescence (RTP) of purely organic materials is easily quenched with unexpected purposes because the excited triplet state is extremely susceptible to external stimuli.

Ultraviolet irradiation-responsive dynamic ultralong organic phosphorescence in polymeric systems

Nature Communications, 2021
Efficient stimulus-responsive phosphorescence organic materials are attractive, but are extremely rare because of unclear design principles and intrinsically spin-forbidden intersystem crossing.

Thermochromic aggregation-induced dual phosphorescence via temperature-dependent sp 3-linked donor-acceptor electronic coupling

Nature Communications, 2021
Aggregation-induced emission (AIE) has proven to be a viable strategy to achieve highly efficient room temperature phosphorescence (RTP) in bulk by restricting molecular motions.

Ultralong phosphorescence cellulose with excellent anti-bacterial, water-resistant and ease-to-process performance

Nature Communications, 2022
Organic room-temperature phosphorescence (RTP) materials often suffer from poor processability because of their crystalline or cross-linked nature.
