Mechanoluminescence or Room-Temperature Phosphorescence: Molecular Packing-Dependent Emission Response

Mechanoluminescence (ML) and room-temperature photophosphorescence (RTP) were achieved in polymorphisms of a triphenylamine derivative with ortho-substitution. This molecular packing-dependent emission afforded crucial information to deeply understand the intrinsic mechanism of different emission forms and the possible packing–function relationship. With the incorporation of solid-state 13C NMR spectra of single crystals, as well as the analysis of crystal structures, the preferred packing modes for ML and/or RTP were investigated in detail, which can guide the reasonable design of organic molecules with special light-emission properties.

Bis(hexamethylazatriangulene)sulfone: A high-stability deep blue-violet fluorophore with 100% quantum yield and CIE: Y < 0.07

Efficient deep blue-violet fluorophores are highly sought after as emitters for OLEDs and as labels for fluorescent imaging. Despite significant progress in the development of deep blue luminescent materials, highly efficient emitters in the deep-blue/violet region of the visible spectrum with good photostability remain rare. Here we describe the preparation of two violet-blue emitters based on hexamethylazatriangulene (HMAT) donors and weakly accepting sulfone and sulfoxide acceptors, with CIE coordinates in solution as low as (0.16, 0.02) and quantum yields of unity. By restricting freedom of motion in the HMAT donor, stability of the sp2 C-N bonds is increased significantly, increasing photostability over controls with nonplanar donors while also narrowing the emission bandwidth to 39.5 nm FWHM. These materials were then evaluated in proof-of-concept experiments for both two-photon excited fluorescence and as emitters in OLEDs to demonstrate their potential applications in optoelectronics.
