简单介绍


ossila材料POSTF  的详细介绍

POSTF has an orthogonal molecular structure with an electron donating spiro[acridine-9,9'-fluorene] core and one electron withdrawing diphenylphosphine oxide attachment to the fluorene unit at 2-poistion.

Bipolar POSTF can be used as a single or together with PO-T2T as an exciplex phosphorescent host for highly efficient blue, green and red phosphorescence devices. Using POSTF as the host, large-size white light-emitting panel (15 cm × 15 cm) with max power efficiency of 75.9 lm W-1 can be achieved [1].
