On the Prevalence of Room-Temperature Protein Phosphorescence [PDF]

Science, 1987
A large number of proteins were tested for the property of intrinsic phosphorescence in deoxygenated aqueous solution at room temperature. The majority of proteins exhibit phosphorescence under normal solution conditions. Phosphorescence lifetimes from 0.5 millisecond to 2 seconds were observed in three-fourths of the proteins tested.

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 ...

Effect of Gold(I) on the Room‐Temperature Phosphorescence of Ethynylphenanthrene [PDF]

Chemistry – A European Journal, 2020
AbstractThe synthesis of two series of gold(I) complexes with the general formulae PR3‐Au‐C≡C‐phenanthrene (PR3=PPh3 (1 a/2 a), PMe3 (1 b/2 b), PNaph3 (1 c/2 c)) or (diphos)(Au‐C≡C‐phenanthrene)2 (diphos=1,1‐bis(diphenylphosphino)methane, dppm (1 d/2 d), 1,4‐bis(diphenylphosphino)butane, dppb (1 e/2 e)) has been realized.

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.
