We describe the synthesis, computational analysis, photophysics, electrochemistry and electrochemiluminescence (ECL) of a series of compounds formed of two triphenylamines linked by a fluorene or spirobifluorene bridge. The phenylamine moieties were modif

Three triphenylamine (TPA) derivatives, constructed by the introduction of halogen atoms in TPA, show strong mechanoluminescence emissions, partially due to their various electronic configurations by virtue of the electron withdrawing ability of halogen atoms. Careful investigation of their single crystals and the density functional theory (DFT) calculations based on the crystal structure demonstrate that the enhanced intermolecular interactions and the twisted molecular structure contribute to their strong ML emission.

A one-pot domino N-arylation protocol is described using diaryliodonium reagents under copper catalysis. The reaction uses both aryl groups of the diaryliodonium reagent to generate triarylamines starting from simple anilines, representing an atom-economical preparation of an important class of organic material building blocks.

The synthesis, structural, photophysical, electrochemical and electroluminescent properties of a novel class of bifunctional molecule are reported in which the hole-transporting triarylamine and electron-transporting oxadiazole components were combined. The strongly luminescent compounds displayed good thermal and morphological stability as well as intense fluorescence both in solution and thin film at room temperature. The effects of the introduction of substituents with different electronic properties upon their absorption and emissive characteristics were correlated with theoretical calculations using density functional theory computations. The photophysics and electrochemistry of such systems were compared to those for the corresponding molecule without an oxadiazole ring. The bipolar compounds could be vacuum-sublimed and applied as emissive dopants for the fabrication of electrofluorescent, organic light-emitting devices with relatively simpler device structures, which can emit tunable colors by varying the aryl ring substituents.
