The correlation between chemical structure and photophysical behavior is vital for development of luminogens in the application of optoelectronics. Different donor, acceptor and π-bridge were systematically combined to produce a series of D-π-A-π-D chromo

A 2,2′-bipyridine with bulky triphenylamine substituents in the 6 and 6′ positions of the ligand (6,6′-ditriphenylamine-2,2′-bipyridine, 6,6′-diTPAbpy) was generated. Despite the steric bulk, the ligand readily formed bis(homoleptic) complexes with copper

Three small organic molecules that contained a phenothiazine backbone and triphenylamine (TPA), carbazole (CZ), or anthracene (AN) as a terminal electron donor were synthesized and fabricated in ITO/organic film/Al sandwiched memory devices. The influence

Organic luminescence with different forms continues to be one of the most active research fields in science and technology. Herein, an ultra-simple organic molecule (TPA-B), which exhibits both mechanoluminescence (ML) and photo-induced room-temperature phosphorescence (RTP) in the crystalline state, provides an opportunity to reveal the internal mechanism of ML and the dynamic process of photo-induced RTP in the same molecule. Through the detailed investigation of photophysical properties together with crystal structures, the key role of molecular packing and intermolecular interactions was highlighted in the luminescence response by mechanical and light stimulus, affording efficient strategies to design potential smart functional materials with multiple luminescence properties.

A series of heteroleptic cyclometalated platinum(II) complexes, [Pt(C^N)(O^O)], (1–10) with various donors and acceptors has been synthesized and characterized by 1H NMR spectroscopy, elemental analyses, infrared spectroscopy and mass spectrometry. The X-ray structure of 2 has also been determined. The electrochemical and photophysical properties of the platinum(II) complexes were studied. These experimental results have been supported by computational studies. Furthermore, two of the complexes have been employed as the active material in the fabrication of resistive memory devices, exhibiting stable binary memory performance with low operating voltage, high ON/OFF ratio and long retention time.

Three new triphenylamine-BODIPY dyadsBDPT1-3have been designed and synthesized. Their optoelectronic properties were investigated, which revealed strong electronic interactions between the donor and acceptor moieties, together with high sensitivity to the inclusion of alkoxy groups. The properties of the dyads were compared with those of reference compoundsAandBDP1, which exhibit broader absorption in the visible region as a result of the inclusion of donor groups and extended conjugation of the BODIPY core. Fluorescence quenching was also observed, which was attributed to the photoinduced electron transfer, evidenced from solvatochromic measurements, quantum yields and theoretical calculations. The oxidation potentials of new compounds were found to be lower when compared with those of other BODIPY analogues with donor groups attached. The redox, computational, absorbance and emission data suggest that compoundsBDPT1-3exhibit promising properties for their application in organic photovoltaic or light emitting (optoelectronic) devices.
