  Synthesis and Characterization of New Self-Assembled Metallo-Polymers Containing Electron-Withdrawing and Electron-Donating Bis(terpyridine) Zinc(II) Moieties

  摘要：

  A series of rigid pi-conjugated bis(terpyridines) (M1-M7) bearing electron-acceptor spacer units in 4'-position was synthesized in moderate to high yields by Pd-0-catalyzed Sonogashira cross-coupling reactions. The compounds were fully characterized by NMR spectroscopy, MALDI-TOF mass spectrometry, elemental analysis and their photophysical properties were discussed in detail. These new bis(terpyridines) were applied for the self-assembly reaction with Zn-II ions to form metallo-homo polymers (P1-P7). Broadened NMR signals and UV-vis titration experiments confirmed the successful polymerization. The electro-optical properties of the materials were investigated in detail. Band gaps up to 2.08 eV and bright blue to orange photoluminescence with quantum yields of 18 to 66% were observed strongly depending on the nature of the pi-conjugated bis(terpyridine) system. In combination with electron-donor ditopic terpyridine ligands (MD1 and MD2), two Zn-II random copolymers (R1 and R2) were synthesized. These materials were investigated by UV-vis absorption and photoluminescence experiments in dilute solution and in the solid state, prepared by spin-coating from DMF Solutions. Thereby, random copolymer R2 featured an energy transfer from the donor to the acceptor part in dilute solution.

  纳米级单步电子转移：强耦合的锌卟啉-金卟啉二联体中的超快电荷转移。

  摘要：

  描述了一系列三个新颖的锌（II）-金（III）双卟啉二元化合物（ZnP--S--AuP（+））的合成，电化学性质和光诱导电子转移过程。所研究的系统由两个三芳基卟啉组成，这些三芳基卟啉通过炔烃单元直接连接到内消旋位置，与叔-（亚苯基亚乙炔基）或五（亚苯基亚乙炔基）间隔基连接。在这些二单元组中，估计的中心到中心卟啉之间的分离距离在32至45 A之间变化。吸收，发射和电化学数据表明，由于间隔基直接附着在卟啉上，链接元素之间存在强电子相互作用穿过炔烃单元。在室温下的甲苯中，卟啉锌的光激发几乎导致电荷转移态（。+）ZnP--S--AuP（。）的定量形成，其寿命约为数百皮秒。在该溶剂中，电荷分离态通过卟啉锌三重激发态的中间种群衰减为基态。激发金卟啉可导致能量快速转移至三重态ZnP。在二氯甲烷中，电荷转移反应甚至更快，时间常数低至2 ps，并且也可以通过激发金卟啉来诱导。在后一种溶剂中，使用五-（亚苯基

  A sample holder comprises a spectral encoding material to encode a measurement signal of the sample with a spectral identification signal. The spectral encoding material has the advantage of providing an encoded signal with the measurement signal, which can help to ensure that the sample is appropriately identified. The sample holder may comprise one or more of a support, a container, a waveguide, or a substrate. The spectral encoding material may comprise a spectrally encoding solution, spectrally encoding particles, or one or more spectrally encoding layers of material. The spectral encoding material may comprise a calibration material, such as a polymer.
