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.

Liquid crystalline copper(i) complexes with bright room temperature phosphorescence [PDF]

, 2020
Phosphorescence in the liquid crystal state with one of the highest quantum yield values, 42%, at room temperature is reported. This property is achieved with cyclic trinuclear copper(I) complexes prepared using 3,5-dimethyl-4-(trialkoxyphenyl)pyrazolate

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.

A Readily Obtained Alternative of 1H-benzo[f]indole towards Room Temperature Ultralong Organic Phosphorescence [PDF]

, 2022
1H-benzo[f]indole (Bd) is a significant unit in the field of room temperature ultralong organic phosphorescence (RTUOP). However, the synthesis of Bd is rather hard and of low yield, which greatly limits the wide applications of RTUOP.
