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 ...

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.
