Synthesis and photophysical properties of new through-space conjugated luminogens constructed by folded tetraphenylethene

Through-space conjugation refers to a unique non-covalent electronic coupling interaction typically occurring between two face-to-face parallel aromatic units, which has shown great potential in constructing novel functional materials capable of multidimensional carrier and energy transportation. However, well-studied through-space conjugation systems are quite rare. In this work, a series of tailored through-space conjugated luminogens are readily constructed from the folded tetraphenylethene (TPE) core and common functional groups like fluorene, carbazole, imidazole and dimesitylborane. Systematic studies on their photophysical properties were conducted, and a deep insight into the structure-property relationship is gained. The new molecules show aggregation-enhanced emission (AEE) characteristics with high fluorescence quantum efficiencies of up to 54% in films. Through the binding experiments of fluoride ions with boron atoms, the impacts of through-space conjugation on the photophysical properties of the luminogens are carefully studied. All these results undoubtedly provide important clues to the rational design of efficient through-space conjugated materials with specific functions.

Synthesis and characterization of a green-light-emitting (pbi-Br)2Ir (acac) metal complex for OLEDs

We designed and synthesized a 2-(4-bromophenyl)-1-phenyl-1H-benzimidazole (pbi-Br) ligand, which was then employed to create an innovative phosphorescent cyclometallated iridium(III) (pbi-Br)2Ir(acac) metal complex with acetyl acetone as an ancillary ligand using the Suzuki coupling reaction. The complex was then characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectra and thermogravimetric analysis (TGA)/differential thermal analysis (DTA) for structural and thermal analysis, respectively. XRD confirmed its amorphous nature and the FTIR spectrum revealed the molecular structure confirmation of the metal complex. The TGA/DTA curve disclosed its thermal stability up to 310°C. Ultraviolet (UV)–vis absorption and photoluminescence (PL) spectra were measured to explore the photo-physical properties of the (pbi-Br)2Ir(acac) complex in basic and acidic media respectively. With the variation in solvent from acidic to basic media, optical absorption peaks blue shifted with variation in optical densities. These results facilitated the calculation of various photo-physical parameters. When excited at 379?nm in the solid state, the synthesized complex gave out a green light emission, peaking at λemi?=?552?nm. Staggering differences in optical density were observed in the PL spectra of the solvated complex. A Stokes’ shift of 7140.45?cm?1 and 7364.94?cm?1 was observed when the complex was solvated in acetic acid and chloroform, respectively. Hence the synthesized iridium metal complex can be considered as promising green emissive material for optoelectronic applications.
