A series of Pt(II) complexes with tetradentate luminophores has been designed, synthesized, and deposited on coinage metal surfaces with the aim to produce highly planar self-assembled monolayers. Low-temperature scanning tunneling microscopy (STM) and density functional theory (DFT) calculations reveal a significant initial nonplanarity for all complexes. A subsequent metal-catalyzed separation of

Functionalized N,O-bridged calix[1]arene[4]pyridines, first examples of the odd-numbered heterocalixaromatics containing mixed heteroatom bridges and mixed aromatic units, have been synthesized from the Pd2(dba)3/dppp-catalyzed 2+3 macrocyclic fragment coupling reaction between readily available staring materials. These novel macrocyclic compounds, which adopted distorted 1,3-alternate conformation
由Pd 2(dba)3 / dppp催化的2+ 3大环片段之间容易发生凝结物的偶合反应。这些新颖的固态大环化合物采用扭曲的1,3-交替构象,是强大的宿主分子,能够与富勒烯C 60在溶液中形成1:1络合物,结合常数高达49,494 M -1。

“U” shaped conformation. For complex 7, the bppa unit of L chelates a Co(II) atom, and a pyridyl nitrogen of the 4,4′-dpa unit bridges another Co(II) atom, thus affording a 1D chain structure. Similar to that observed in 7, each L ligand in complex 8 links two Cu(II) ions, and a μ1,3-azide further bridges two Cu(II) ions from neighbouring chains, affording a 2D undulated layer, which is interpenetrated
