Synthesis of luminescent gold organometallic complexes containing triphenylene ligands

Abstract

From the beginning of the century, there has been an increasing interest in the research of organometallic complexes with luminescent properties. Due to their wide range of applications, they can be useful as light emitting diodes, chemosensors, etc. In this project, gold(I) luminescent complexes have been studied and synthesized. Two triphenylene (TP) based derivatives with alkynyl moieties have been used, METP and HETP, as the polycyclic aromatic hydrocarbons (PAH) ligand of the complex. On the other hand, different phosphine ligands were employed to complete the gold(I) coordination, such as PPh3, PEt3, PMe3 and DAPTA. The obtained products have been characterized using the usual techniques such as 1H, 31P and 13C NMR, HSQC, COSY, IR and mass spectrometry. The luminescent properties of these compounds have been determined by recording the absorption and emission spectra.
