Organoimido-Polyoxometalate Nonlinear Optical Chromophores: A Structural, Spectroscopic, and Computational Study
Ten organoimido polyoxometalate (POM)-based chromophores have been synthesized and studied by hyper-Rayleigh scattering (HRS), Stark and Resonance Raman spectroscopies, and density functional theory (DFT) calculations. HRS β0 values for chromop

Synthesis and structure of [2.2]paracyclophanes incorporating alkyne units in the extended linear chain
The novel [2.2]paracyclophanes 4-7 with an extended π-conjugation due to the presence of a linear arylethynyl chain have been synthesized by the Pd-catalyzed Sonogashira coupling reaction.
This invention is generally related to a method of making a molecule-surface interface comprising at least one surface comprising at least one material and at least one organic group wherein the organic group is adjoined to the surface and the method comp

Synthesis of nanometer-sized homo- and heteroorganometallic tripodaphyrins
Tripodaphyrins are tetrahedral or pyramidal assemblies in which a porphyrin macrocycle situated on the top of the molecule is 'supported' by three 'legs' consisting of linear arrays of covalently linked rigid constitutive elements. The edge-length at the 'base' of the molecules which have been synthesized until now lies in the range from 3.2 to 6.5 nm. In some tripodaphyrins (3a-c) the chromophore situated on the top of the molecule differs on the complexed metal ion from the other three, which are located at the ends of the 'legs'. Owing to the dimensions of the molecules, no intramolecular interaction between the chronophores is observed, even in the presence of a paramagnetic Cu(II) chelate.
