“…The Pd4⋅⋅⋅Pd6 distance in complex 1 is 17.41 Å. The average PdN and PdO bond lengths are in the range of 2.01–2.06 and 1.97–2.03 Å respectively, consistent with reported values 3p. Complex 1 was synthesized in high yield by reacting [(tmen)Pd](NO 3 ) 2 , tib, and stt in an 8:2:5 ratio in aqueous medium.…”

Systematic investigation on synergetic effects of geometry, length, denticity, and asymmetry of donors was performed through the formation of a series of uncommon Pd(II) aggregates by employing the donor in a multicomponent self-assembly of a cis-blocked 90° Pd(II) acceptor and a tetratopic donor. Some of these assemblies represent the first examples of these types of structures, and their formation is not anticipated by only taking the geometry of the donor and the acceptor building units into account. Analysis of the crystal packing of the X-ray structure revealed several H bonds between the counteranions (NO3 (-) ) and water molecules (OH⋅⋅⋅ON). Moreover, H-bonded 3D-networks of water are present in the molecular pockets, which show water-adsorption properties with some variation in water affinity. Interestingly, these complexes exhibit proton conductivity (1.87×10(-5) -6.52×10(-4) Scm(-1) ) at 296 K and low relative humidity (ca. 46 %) with activation energies of 0.29-0.46 eV. Moreover, the conductivities further increase with the enhancement of humidity. The ability of these assemblies to exhibit proton-conducting properties under low-humidity conditions makes these materials highly appealing as electrolytes in batteries and in fuel-cell applications.

“…Another group formed a highly ordered array of TMPyP on a sulfate/bisulfate adlayer on a Cu(111) surface. 76 Highly ordered arrays of various organic molecules can be found on chloride-modified Cu(100), 77,78 I-Cu(111), bromine-modified Au(111), 79 and sulfate adlayers on Au(111). 80 Thus, two-dimensional organization of water-soluble porphyrins has been achieved at electrochemical interfaces.…”

In the electrochemical surface science during the past 20 years, in-situ electrochemical scanning tunneling microscopy (EC-STM) and atomic force microscopy (AFM) have made significant contribution to understand various electrochemical processes with atomic scale. For examples, the underpotential deposition of copper, silver, and other metal ions; the specific adsorption of anions such as iodine and sulfate/bisulfate ions; electrochemical etching processes of metals and semiconductors and the molecular assembly of many organic molecules, such as metalloporphyrins, and metallophthalocyanines. Furthermore, we have recently developed a high resolution laser confocal microscope, combined with a differential interference contrast microscope, which enables to follows fast dynamic electrochemical processes at atomic height resolution in relatively large areas. It has been shown for the first time that single atomic steps of metals can be successfully seen by the newly developed optical microscope. Surface imaging techniques provide local pictures of electrode processes on the atomic scale, not averaged information in large areas.

“…One of the most prominent natural templates, i.e. single-stranded DNA, could be called a linear template according to this classification and a surface on which molecules self-assemble into an ordered array [14] may be coined a planar template. A beautiful example of a planar template is a recently reported electropolymerization using a liquid crystalline phase as the template [15].…”
