Radical-enhanced photo-activated ultralong organic phosphorescence.

ABSTRACT: Stimuli-responsive ultralong room temperature phosphorescence materials have attracted great attention due to their great potential in a wide variety of advanced applications. Photo-activated phosphorescence lifetime and photo-activation time are constant and highly dependent on the inherent properties of the materials. It is a great challenge to manipulate them. Herein, we propose a facile strategy to prolong photo-activated phosphorescence emission and shorten photo-activation time by consuming the oxygen in polymer matrix through UV irradiation and radical coupling. The phosphorescence lifetime increases from 0.08 ms to 360 ms after 30-minute UV irradiation. When the guest molecules in solution are photoactivated and subsequently doped into the polymer, the photoactivated phosphorescenc
