  摘要：

  The der-ay pathways of the lowest excited singlet state (1t*) of trans-1-(9-anthryl)-2-(4-R-phenyl)ethylenes (trans-R-StAs, where R = N(CH3)2, OCH3, CH3, Br, CN, and NO2 On the 4-Position of the styryl) were studied in solution at room and low temperatures. Fluorescence lifetime (tau(f)) and quantum yield (PHI(f)) as well as the yield (PHI(T)) and spectral and kinetic properties of the lowest triplet state were determined by steady-state and transient techniques. The solvent polarity has a large effect on the Stokes shift for (H3C)2N- and O2N-StA, the two derivatives with the strongest electron-donating and -accepting substituents. The smallest changes in PHI(f) and PHI(T), in comparison with the case of parent 9-StA, are caused by the Br or CH3 groups. For O2N- and (H3C)2N-StA, and to a lesser degree for NC- and H3CO-StA, PHI(f) and tau(f) become significantly smaller with increasing solvent polarity. Efficient deactivation by charge transfer via an excited singlet state with essentially trans configuration (A*) is proposed for these derivatives. The 1t* --> A* relaxation pathway in polar solvents is activated and competes with fluorescence and intersystem crossing. For NC-, H3CO-, and (H3C)2N-StA at room temperature trans --> cis photoisomerization occurs with substantial quantum yield (PHI(t --> c)) in those solvents in which the presence of the postulated A*-state efficiency reduces fluorescence and intersystem crossing. A contribution of a triplet mechanism to trans --> cis photoisomerization can be excluded throughout. A special case is O2N-StA, which exhibits virtually no photochemistry in both nonpolar and polar solvents, but PHI(t --> c) is up to 0.2 in slightly polar solvents, e.g., toluene.

• Preparation of Functionalized Polystyrene-<i>b</i><i>lock</i>-polyisoprene Copolymers and Their Luminescence Properties

  A series of block copolymers functionalized with aromatic 1,3,4-oxadiazole and stilbene, derivatives have been synthesized by the palladium catalyzed reaction between polystyrene-block-polyisoprene and different functional units. These polymers exhibited different emission properties in solution and in the solid state. In chloroform solution, they showed relatively narrow and featured emission bands while, in the solid state, the emission band was broadened and showed a significant red shift. These observations were attributed to the formation of aggregates between the luminophores. After some oxadiazole functionalized copolymers were annealed at elevated temperature, such aggregation was enhanced and there were further changes in the emission spectra. For the bifunctional copolymers, such a shift in the emission band was not significant because the presence of two different chemical species in the same block may prevent the same type of luminophores from aggregating together.
• Synthesis and spectroscopy of anthracene-containing linear and ‘T’-shaped π-conjugated ligands

  A range of new it-conjugated ethynyl- and diethynyl-benzene ligands has been synthesised and their spectroscopic characterisation carried out, most notably via IR and H-1 NMR. X-ray crystal structures were obtained for three of these ligands and one unusual ruthenium complex. Both the 4-ethynyl- and 2,5-diethynyl-benzene cores of these compounds have been functionalised through organic transformations by addition of an 9-anthracenyl. This has been attached via a range of linker moieties that vary in both their length and degree of pi-conjugation. This has given rise to two groups of compounds with either a linear, e.g., 9-(2-(4-ethynylphenyl)ethynediyl)anthracene and 9-(2-(4-ethynylphenyl)ethyl)anthracene, or 'T'-shaped morphologies, e.g., 9-(2-(2,5-diethylnylphenyl)ethyl)anthracene.
