Regulation of various photo-active UOPs in a polymer matrix by tuning intermolecular charge transfer

Abstract

Polymer-based ultralong organic phosphorescence (UOP) materials have attracted considerable attention for their characteristic of simple process, low cost, large-scale preparation and stable performance. However, the organic phosphorescent emitters capable of...

Controlling the efficient and ultralong room-temperature phosphorescence of 9H-dibenzo[a,c]carbazole derivatives for erasable light printing

“…values may be recorded from BCzS under similar conditions. 63,64 In addition, the natural transition orbital (NTO) analysis reveals that the T 1 excited states of the luminophores are mainly characterized by a 3 ππ* configuration. 65 Their holes distribute at the DBCz moiety, while the particles extend to the phenyl ring attached to the nitrogen atom.…”
