英语翻译
conjugated
ligands are particularly attractive building blocks for
self-assembly reactions,because cofacial molecular aggregation
can maximize the orbital interactions between two
p systems,thus leading to rich photophysical and photochemical
properties that can be harnessed for optoelectronic
applications and light-energy conversion reactions.[9] Intermolecular
PtII···PtII interactions play a key role in the close
packing of molecules.To date,quasi-one-dimensional nanowires
have been obtained by self-organization of organoplatinum(
II) complexes,presumably owing to the fact that
molecular propagation is faster along the PtII···PtII chain axis
than in the lateral directions.We and others have taken
advantage of this anisotropic growth mechanism to assemble
cationic organoplatinum(II) salts into nanostructures with
luminescent,semiconducting,liquid crystalline,and gelating
properties.[10] Herein we report free-standing and crystalline
nanosheets self-assembled from neutral pincer-type[11] cyclometalated
platinum(II) aryl acetylides.Indeed,intermolecular
PtII···PtII and C\2H···p(C\3C)[12] interactions in an orthogonal
configuration account for the quasi-2D molecular
organization herein.Notably,these organometallic nanosheets
luminesce in the red to near infrared (NIR) region,and
their electronic conductivity can be modulated by visible-light
irradiation.

共轭配体是用于自组装反应特别吸引人的基本成分,因为共面的分子共轭可以使两个π体系之间的轨道互作用最大化,从而导致可以被利用于光电子应用和光－能量转换反应的丰富的光物理和光化学性质[9].分子间PtII…PtII互作用在分子的闭合封装中起关键的作用.至今,准一维纳米线已经通过有机铂（II）络合物的自组织（有机化）而获得,这大概是由于分子的传播沿PtII…PtII链的轴线比在横向更快的事实引起的.作者和其他研究人员已经利用这一各向异性的生长机理将阳离子的有机铂（II）盐组装成纳米结构,它们具有发光、半导电、液晶和凝胶作用等性质[10].这里,我们报道了由中性的镊子型[11]环金属铂（II）芳香基乙炔化物自组装的无束缚和结晶纳米片.确实,这里在正交结构中的分子间PtII…PtII和C－H…π（C≡C）[12]互作用解释为准二维的分子组织（有机化）作用.尤其是这些有机金属纳米片在红色到计划外（NIR）区发光,而他们的电子电导率可以用可见光辐照来调整.
