  Synthesis, Morphology, and Optical Properties of Tetrahedral Oligo(phenylenevinylene) Materials

  摘要：

  A novel topological strategy is described for designing amorphous molecular solids suitable for optoelectronic applications. In this approach, chromophores are attached to a tetrahdral point of convergence. Stilbenoid units were covalently linked to tetraphenylmethane, tetraphenyladamantane, or tetraphenylsilane cores using palladium catalyzed coupling methodology, Thus, reaction of E(C6H5X)(4) (E = C and adamantane, X = I; E = Si, X = Br) with styrene or 4,3'-tert-butylvinylstilbene under Heck coupling conditions yields the corresponding tetrakis(stillbenyl) (E(STB)(4)) and tetrakis(4-tert-butyIstyrylstilbenyl) (E((BuSSB)-Bu-t)(4)) compounds. Similarly, reaction of 1,1-diphenyl-2-(4-dihydroxyboronphenyl)ethene or 2-(4-pinacolatoboronphenyl)-3,3-diphenylacrylonitrile with tetrakis(4-bromophenyl)methane using Suzuki coupling methodology gives tetrakis(4,4'-(2,2-diphenyl-vinyl)-1,1'-biphenyl (C(DPVBi)(4)) or tetrakis(4,4'-(3,3-diphenylacrylonitrile biphenyl)methane (C(DPAB)(4)), respectively, in good yields. Compounds with more extended conjugation can also be prepared. Thus, reaction of excess 1-(4'-tert-butylstyryl)-4-(4'-vinylstyryl)benzene with C(C6H4I)(4) provides tetrakis(4-(4'-(4"-tert-butylstyryl)styryl)stilbenyl)methane (C(4R-Bu-t)(4)) in low yield (similar to 20%). The more soluble analogue, tetrakis(4-(4'-(3",5"-di-tert-butylstyryl)stilbenyl)methane (C(4R-2(t)Bu)(4)) is prepared similarly using 1-(3',5'-di-tert-butylstyryl)-4-(4'-vinylstyryl)benzene and in better yield (similar to 80%). Alkoxy substituents can also be used to increase solubility. Tetrakis((4-(2',5'-dioctyloxy-4'-styryl)styryl)stilbenyl)methane methane, C(4R-(OC8H17)(2))(4), was prepared by treatment of C(C6H4I)(4) with excess 2,5-dioctyloxy-1-styryl-4(4'-vinylstyryl)benzene (yield similar to 73%). The simple stilbenyl-derivatives were found by DSC measurements and powder diffraction experiments to be crystalline compounds. Comparison of single-crystal X-ray diffraction data shows that C(STB)(4) and Si(STB)(4) form isomorphous crystals. The larger E((BuSSB)-Bu-t)4, C(DPVBi)(4), and C(DPAB)(4) compounds readily form amorphous glasses with elevated glass transition temperatures (T-g = 142-190 degrees C) in the absence of solvent. Extending the conjugation length of the arm leads to more stable glasses. For example, the glass transition temperature of C(4R-Bu-t)(4) was measured at 230 degrees C. Solution phase optical spectroscopic data of E((BuSSB)-Bu-t)(4) (E = C, adamantane, and Si) are characteristic of the parent distyrylbenzene chromophore. Films, however, show broad and significantly red-shifted emission spectra. In contrast, C(DPVBi)(4) gives absorption and emission spectra which are nearly identical between dilute solution phase samples and neat solid films. The emission of C(DPAB)(4) is broad and structureless, reminiscent of exciplex or excimer emission. Films of the tetramers with longer arms (C(4R-Bu-t)(4), C(4R-2(t)Bu)(4), and C(4R-(OC8H17)(2))(4)) show emission properties which are dependent on sample history. Annealing the sample at elevated temperature leads to red-shifted emission as a result of better interdigitation between the optically active fragments.

  具有聚集诱导的发射和分子内电荷转移特性的高效固体发射体：分子设计，合成，光物理行为和OLED应用

  摘要：

  发射电子供体-受体（DA）共轭物在生物光子学，双光子吸收材料，有机激光器，长波长发射器等方面具有广泛的应用。但是，由于臭名昭著的聚集引起的猝灭（ACQ）效应，合成高固态效率D–A结构化的发射器仍然是一个挑战。尽管据报道某些D–A系统显示出聚集诱导排放（AIE）行为，但大多数系统在高极性溶剂中仅具有选择性AIE活性，与非极性溶剂相比，其固相排放效率降低。在这里，我们报告基于三苯胺（TPA）和2,3,3-三苯基丙烯腈（TPAN）的D–A体系结构，即TPA3TPAN和DTPA4TPAN。用TPAN修饰芳胺会改变其发射行为，从ACQ变为AIE，使所得的TPA3TPAN和DTPA4TPAN在普通溶剂中不发光，但由于其高度扭曲的构型而聚集成纳米颗粒，固体粉末和薄膜时具有高发射性。由于它们的分子内电荷转移（ICT）属性，这两种化合物还显示出红移效应。结合了ICT和AIE功能，使TPA3TPAN和DTPA

  The optical properties and piezofluorochromic behaviour of N,N′-dioctyl-1,7-di(4-(1,2,2-triphenyl)vinyl)phenyl-3,4:9,10-tetracarboxylic perylenebisimide (PBI–TPE) have been investigated. PBI–TPE shows strong fluorescence in non-polar solvents, in contrast to complete quenching in common moderately polar to polar solvents, most likely due to intramolecular charge transfer (ICT) from the donating tetraphenylethene (TPE) groups to the acceptor perylenebisimide core. The solid-state fluorescence is morphology dependent, in which the amorphous-state displays near infra-red emission at 744 nm and the crystalline state shows a blue-shift in emission at 665 nm with a difference of 79 nm. Crystalline PBI–TPE exhibits stress induced amorphisation resulting in a piezo-responsive behaviour in which the metastable amorphous state and crystalline state can be interconverted by grinding and thermal annealing (200 °C)/recrystallisation. This reciprocal conversion gives rise to the piezofluorochromic effect. Finally, crystalline microstructures were used to fabricate a microwire field-effect transistor (MFET) with the effective mobility (μe) and capacitance (Ci) estimated to be 3.11 × 10−5 cm2 V−1 s−1 and 1.51 × 10−15 F, respectively.

  产生单线态氧 ( 1 O 2 ) 的光敏剂在开发新型光动力治疗剂和促进1 O 2涉及的化学反应方面受到高度关注。单线态氧通常是由三线态激发光敏剂与双氧通过能量转移机制反应产生的。在本研究中，我们展示了一种产生单线态氧的电荷转移机制，涉及推或拉功能化卟啉。为此，新合成了 20 种带有富电子推基或缺电子拉基的 β-吡咯功能化卟啉。这些推拉卟啉的光激发已被证明可产生高能 MP δ+ -A δ−或 MP δ – -D δ+电荷转移态。在含有卟啉的推动基团的情况下，随后的电荷重组导致延长寿命的三线态激发态，最终与双氧反应产生相对较高量子产率的反应性单线态氧。系统地探讨了卟啉外围的推拉基团在控制初始电荷转移、三重激发态的数量及其寿命以及提高单线态氧量子产率方面的影响。这项研究证实了携带推动基团的卟啉改善了1 O 2生成的性能。
