Synthesis and photoinduced charge stabilization in molecular tetrads featuring covalently linked triphenylamine-oligothiophene-BODIPY-C60

Two covalently linked tetrads comprised of charge stabilizing triphenylamine (TPA)-oligothiophene (bi- or terthiophene, BT or TT) linked at the meso-position of a well-known photosensitizer, BF2-chelated boron dipyrromethene (BODIPY), was furth

A colorimetric and fluorometric oligothiophene-indenedione-based sensor for rapid and highly sensitive detection of cyanide in real samples and bioimaging in living cells

A new simple oligothiophene-indenedione-based sensor 3TI has been synthesized for the highly reactive and selective detection of cyanide anion (CN?) in 70% aqueous media. The sensor 3TI displays distinct colorimetric and fluorometric detection of CN? due to the addition of CN? to the electron-deficient indenedione-vinyl group of 3TI, which hampers intramolecular charge transfer (ICT) efficiencies. The recognition mechanism of 3TI for CN? was confirmed by the optical measurements, 1H NMR titration, FTIR spectra, HRMS analysis, and TD-DFT calculations. The sensor 3TI for CN? shows the outstanding advantages of high fluorescence brightness, fast response time (30 s), low detection limit (31.3 nM), minimal pH dependence in the physiologically relevant range, and excellent selectivity in presence of other competitive anions. Encouraged by these desirable sensing properties, the 3TI has been successfully used for determination of CN? in real water and food samples, silica-based sensing kits and fluorescence imaging in living cells with satisfactory results.

Aldehyde end-capped terthiophene with aggregation-induced emission characteristics

From the viewpoint of practical application, organic materials that are emissive in aggregate or solid state have been a hot research topic. This work demonstrates that 2,2′:5′,2″-terthiophene-5-carbaldehyde (TTA) exhibited aggregation-induced emission (AIE) property. The photophysical properties of the aldehyde in THF/H2O mixtures were studied, and the aggregates formed with different water fractions were studied by scanning electron microscopy. Our results indicated that the presence of an electron deficient aldehyde group as the end-capped group should endow TTA with AIE characteristic. Furthermore, ordered nanoscale aggregates of TTA exhibited distinct AIE behavior when assembled in solutions with appropriate water content.
