Article Description

A family of robust metal complexes of [Mn(L)X2] and (LH)2[MnX4] type (X = Cl, Br, I) have been synthesized based on xanthene-derived bisphosphine dioxides (L = XantphosO2 or t-Bu-XantphosO2). At ambient temperature, the designed compounds exhibit strong green to yellow phosphorescence with quantum yields as high as 90%. Remarkably, complex [Mn(XantphosO2)Br2] reveals polymorphic luminescence, which is a rare phenomenon for Mn compounds. Two polymorphs of this compound, crystallizing in P1 and P21/n space groups, display green and yellow luminescence, respectively, with the emission quantum yield being 33 and 50%. Moreover, the "yellow"polymorph features bright triboluminescence upon grinding its crystals. An in-depth photophysical study evidences that the observed phosphorescence is due to the ligand-sensitized 4T1 → 6A1 transitions in Mn2+ ions.
