• Steric effect on excimer formation in planar Pt(<scp>ii</scp>) complexes

  In order to understand the steric influence on excimer formation in square planar metal complexes, three different Pt(II) complexes were prepared by modifying the substituents in the main ligand: Pt(II)(dfppy)(acac) (Pt-1, where dfppy is difluorophenylpyridine, acac is acetylacetonate); the bulky triphenyl silyl (Ph3Si–) group was substituted at the pyridine moiety (Pt-2) and at the phenyl moiety (Pt-3)

  为了了解空间对方形平面金属络合物中准分子形成的空间影响，通过修饰主要配体中的取代基制备了三种不同的Pt（II）络合物：Pt（II）（dfppy）（acac）（Pt-1，其中dfppy是二氟苯基吡啶，acac是乙酰丙酮酸盐）；庞大的三苯基甲硅烷基（Ph 3 Si–）基团在Pt-1的主要配体的吡啶部分（Pt-2）和苯基部分（Pt-3）处被取代。铂络合物在约460 nm处显示出天蓝色发射。此外，Pt-1和Pt-3在浓缩溶液和固体样品中显示出约600 nm的准分子发射。单体Pt-1和Pt-3的发射寿命和强度显示出强烈的浓度依赖性。实际上，由于受激准分子的形成，在高浓度溶液中单体的寿命缩短了。考虑到单体发射的自猝灭寿命，通过斯特恩-沃尔默分析确定了本征发射寿命为364 ns（Pt-1）和300 ns（Pt-3）。Pt-2在浓缩溶液或固体样品中未显示任何准分子发射。Pt-1和Pt-3的晶体结构通过X射

  investigated as a method to modulate the photophysical properties of phosphorescent (benzo)porphyrins. For cyclometalation with Pt(II), 2-pyridyl groups were incorporated into three Pd(II) porphyrin complexes. Integration of the freely rotating cyclometalated 2-phenylpyridyl based motif in meso-position does not lead to notable spectral changes and only affects the luminescence decay time (about 2-fold

  研究了环金属化作为调节磷光（苯并）卟啉的光物理性质的方法。为了用Pt（II）进行环金属化，将2-吡啶基结合到三种Pd（II）卟啉配合物中。自由旋转的基于环金属化的2-苯基吡啶基的基序在中间位置的整合不会导致显着的光谱变化，而只会影响室温下溶液的发光衰减时间（减少约2倍）。但是，衰减时间在77 K的冷冻玻璃中或固定在刚性聚苯乙烯基质中均不受影响。相比之下，环金属化在中间位置包含一个2-吡啶基单元和卟啉的β-H导致大的红移（〜1900 cm -1吸收光谱中的Q波段和磷光峰。还观察到磷光寿命大大降低（约20倍）。环金属化反应使单线态氧量子产率提高到85％，使这种新染料成为一种强大的可激发1 O 2的红光光敏剂。
• Azadibenzophospholes: Functional Building Blocks with Pronounced Electron-Acceptor Character
  作者：Stefan Durben、Thomas Baumgartner

  DOI：10.1021/ic200951x

  日期：2011.7.18

  A series of azadibenzophospholes with varying location of the nitrogen center has been synthesized and comprehensively characterized. In the context of the study, suitably brominated phenylpyridine precursors were accessed via Suzuki-Miyaura cross-coupling for the first time. Despite being nonfluorescent, X-ray crystallographic studies of two azadibenzophosphole oxides revealed planar conjugated scaffolds with high degree of pi-conjugation. The P-oxidized species were found to show desirable reversible reduction features that support promising electron-accepting properties of the materials. The presence of the nitrogen as well as phosphorus centers within the scaffold allowed for further functionalization with transition metals, as well as methyl groups that result in altered absorption and redox features for the materials. Subsequent bromination of the scaffold selectively occurred at the exocydic P-phenyl group, as confirmed via X-ray crystallography. This halogenation allowed for further modification of the system via catalytic cross-coupling with pyridine.
• Nonconjugated Dimesitylboryl-Functionalized Phenylpyridines and Their Cyclometalated Platinum(II) Complexes

  To investigate possible through-space charge transfer transitions between a Pt(II) ion and a triarylborane unit, the two new nonconjugated molecules 1 and 2 have been synthesized and fully characterized. Compound 1 has a V-shaped geometry, while 2 has a U-shaped geometry. In 1 a BMes(2)Ar group and a ppy group (Mes = mesityl, ppy = phenylpyridine) are linked together by a SiPh2 unit, while in 2 these groups are joined together by a 1,8-naphthyl linker. The crystal structures of 1 and 2 were determined by single-crystal X-ray diffraction analyses. Their cyclometalated compounds Pt-1 and Pt-2 with a Pt(acac) unit chelated to the ppy site have been synthesized. Computational and experimental examinations on the photophysical properties of the free ligands and the Pt(II) compounds revealed that the molecular shape and geometry of the molecule have a distinct impact on the fluorescence and phosphorescence of these molecules. Pt-1 is a bright, phosphorescent emitter with lambda(em) 490 nm and Phi = 66% while Pt-2 is very weakly emissive with lambda(em) 567 nm and Phi = similar to 0.05%. Anions such as fluoride were found to have no impact on the phosphorescence of these two Pt(II) compounds, thus establishing that phosphorescence of these molecules does not involve a through-space charge transfer transition between the Pt(ppy) (acac) unit and the BMes(2)Ar unit.
