Efficient Intramolecular Charge-Transfer Fluorophores Based on Substituted Triphenylphosphine Donors

Triphenylphosphine (TPP)-based luminescent compounds are rarely investigated because of the low photoluminescence quantum yield (PLQY). Here, we demonstrate that introducing steric hindrance groups to the TPP moiety and separating the orbitals involved in the transition can drastically suppress the non-radiative decay induced by structural distortion of TPP in the excited state. High PLQY up to 0.89 as well as thermally activated delayed fluorescence are observed from the intramolecular charge-transfer (ICT) molecules with substituted TPP donors (sTPPs) in doped films. The red organic light-emitting diodes employing these emitters achieve comparable external quantum efficiencies to the control device containing a classical phosphorescent dye, revealing the great potential of the ICT emitters based on electrochemically stable sTPPs.

Synthesis, Coordination Chemistry and Ligand Properties of Secondary Phosphines R(Ar*)PH with Bulky Aromatic Substituents - Molecular Structure of Ph(2,4,6-iPr3C6H2)PH, (2,4,6-iPr3C6H2)2PH and ClAu[PhP(2,4,6-tBu3C6H2)H]

The secondary phosphines R(Ar*)PH (R = Me, iPr, Ph, Mes, Ar*) (2a-2h) with bulky aromatic substituents Ar* (Ar* = 2,3,6-R′3C6H2, R′ = iPr, tBu) are obtained in good yields by reaction of RPCl2, PCl3, PBr3 or Ar*P(Cl,Br)2 with 2,4,6-tBu3C6H2Li or 2,4,6-iPr3C6H2MgBr and subsequent reduction of the intermediate halophosphines R(Ar*)PX (X = Cl, Br) with LiAlH4. The X-ray structural analysis of Ph(2,4,6-iPr3C6H2)PH (2g), space group P1, shows P-C-distances of 1.824(1) and 1.838(1)?. The lithium derivatives of 2a-2c are monomeric in solution as indicated by the 1 : 1 : 1 : 1-quartet 7Li-31P fine structure of the 31P{1H} NMR signals at low temperatures. 2a-2c and 2f-2h form Ni(0) and Fe(0) complexes (CO)3NiL (6a-6f) and Fe(CO)4L (7a-7d), respectively. The Tolman electronic parameters ν of the bulky ligands are almost identical. Within the series 2a-2h the spatial shielding of the P atoms has been estimated using advanced molecular modeling techniques. The bulky ligancl 2c forms coinage metal complexes [Cu(CH3CN)2(2c)2] [PF6] (8). Cu2Cl2(2c)2 (9) and Cl-Au(2c) (10). While 10 is monomeric in solution, in the solid state it forms pairs of head to tail oriented monomers with almost linear Cl-Au-P skeletons (Cl-Au-P 175.47(9)°) as shown by an X-ray structural analysis.
