Multi-dipolar Chromophores Featuring Phosphine Oxide as Joint Acceptor: A New Strategy toward High-Efficiency Blue Thermally Activated Delayed Fluorescence Dyes

Blue thermally activated delayed fluorescence (TADF) dyes are basically combinations of strong acceptors and weak donors. In this work, a weak acceptor P=O group was employed to construct a series of weak acceptor-strong donor (WASD)-type emitters with a phenoxazine donor, namely 10-(4-(diphenylphosphoryl)phenyl)-10H-phenoxazine (SPXZPO), 10,10′-(4,4′-(phenylphosphoryl)bis(4,1-phenylene))bis(10H-phenoxazine) (DPXZPO), and 10,10′,10″-(4,4′,4″-phosphoryltris(benzene-4,1-diyl))tris(10H-phenoxazine) (TPXZPO). Owing to the insulating effect of P=O on conjugation extension and intramolecular electronic communications, the photoluminescence spectra of these molecules are almost identical, manifesting the superiority of WASD structure in emission color preservation. Simultaneously, the multi-dipolar characteristics of TPXZPO enhance the intramolecular charge transfer (ICT), facilitating reverse intersystem crossing for higher TADF efficiency and shorter lifetime. As a consequence, TPXZPO realized the desired pure-blue electroluminescence peak at 464 nm, accompanied by a favorable external quantum efficiency (ηext) up to 15.3%, 100% exciton utilization, and reduced efficiency roll-offs. Its complementary full-TADF white organic light-emitting diodes also achieved ηext as high as 16.3%, among the best results reported so far for white TADF devices. The success of TPXZPO, the first example of a P=O-based WASD-type blue TADF dye, is attributed to the comprehensive and harmonized effects of the P=O joint on controlling conjugation and intramolecular electronic communication and the multi-dipolar structure on enhancing ICT.

Molecular Design of Thermally Activated Delayed-Fluorescent Emitters Using 2,2′-Bipyrimidine as the Acceptor in Donor–Acceptor Structures

Donor–acceptor–donor (D–A–D)-type thermally activated delayed fluorescence (TADF) emitters 5,5′-bis{4-[9,9-dimethylacridin-10(9H)-yl]phenyl}-2,2′-bipyrimidine (Ac-bpm) and 5,5′-bis[4-(10H-phenoxazin-10-yl)phenyl]-2,2′-bipyrimidine (Px-bpm), based on the 2,2′-bipyrimidine accepting unit, were developed and their TADF devices were fabricated. The orthogonal geometry between the donor unit and the 2,2′-bipyrimidine accepting core facilitated a HOMO/LUMO spatial separation, thus realizing thermally activated delayed fluorescence. The exhibited electroluminescence ranged from green to yellow, depending on the donor unit, with maximum external quantum efficiencies of up to 17.1 %.

The role of distance between donor and acceptor in configuration stability of Z/E isomers based on cyanostilbene

Cyanostilbene has been widely used in the design of photoelectrical materials, and our previous work has confirmed its Z/E isomerization reaction under photoirradiation can be suppressed by forming a suitable donor-acceptor (D-A) structure. In this work, we report two D-A cyanostilbene derivatives with AIE activity, abbreviated as PZPNC and PZNC, whose chemical structures only differ by one more phenyl between donor and acceptor. Their Z/E isomers were characterized with single crystal structures and the impact of D-A distance on their stability of Z/E configuration was studied. The in-situ UV–vis spectra and HPLC results of Z/E-PZPNC and Z/E-PZNC under photoirradiation demonstrated that the Z/E isomerization reaction of PZNC was slower than PZPNC, indicating that the shorter D-A distance is conductive to the stability of cyanostilbene due to the relatively stronger charge transfer state with lower energy.
