Differing HOMO and LUMO mediated conduction in a porphyrin nanorod.

چکیده
In this communication we provide the first UHV-STM images and STM-based current-voltage (I-V) and orbital mediated tunneling spectroscopy (OMTS) data on a self-assembled porphyrin nanostructure at the single structure level. We will show that transverse conductivity over distances less than 10 nm can occur by barrier type tunneling but that long distance conduction solely occurs through the LUMO band. These nanorods are very highly rectifying.

Computational design of concomitant type-I and type-II porphyrin sensitized solar cells.
Structures and electronic properties of porphyrins with various Donor (D)-Acceptor (A) functionalization adsorbed on TiO2 (anatase) nanoparticles are studied using DFT calculations. Adsorption of porphyrin leads to a substantial loss of planarity (puckering) for the porphyrin rings due to the stabilization of the system by the interaction of the lone-pair of electrons of the N-atoms of porphyri...
متن کاملExperimental and computational evidence of the intermolecular motifs in the crystal packing of luminescent pentacoordinated gallium(III) complexes.
This paper reports the synthesis, characterization, photophysical and structural properties of the homologous series of good emitting pentacoordinated GaQ'2L complexes 1-3, where Q' is 2-methyl-quinolin-8-olate and L is a phenolate substituted in para position with respect to the oxygen donor atom. A combined approach between the experimental structural analysis (i.e. the molecular fragments in...
متن کاملThe Role of Porphyrin-Free-Base in the Electronic Structures and Related Properties of N-Fused Carbazole-Zinc Porphyrin Dye Sensitizers
Dye sensitizers can significantly affect power conversion efficiency of dye-sensitized solar cells (DSSCs). Porphyrin-based dyes are promising sensitizers due to their performances in DSSCs. Here, based upon a N-fused carbazole-zinc porphyrin-free-base porphyrin triad containing an ethynyl-linkage (coded as DTBC), the novel porphyrin dyes named DTBC-MP and DTBC-TP were designed by varying the p...
متن کاملSynthesis and properties of novel donor-type metal–dithiolene complexes based on 5,6-dihydro-1,4-dioxine-2,3-dithiol (edo) ligand{
Metal–dithiolene complexes form very attractive categories of molecular metals and superconductors. They can have various oxidation states and can range from electron acceptors to donors. The first observation of metallic behavior in crystalline metal– dithiolene complexes was reported for Li0.75[Pt(mnt)2]?2H2O [mnt~maleonitriledithiolate; Scheme 1] by Underhill et al. in 1981. The conduction p...

In this work, we have studied binding of Clonidine drug (C9H9Cl2N3) with zigzag single walled carbonnanotubes (SWCNT) (5, 0) by theoretical methods of theory using Gaussian 09 software package.Binding energies, NMR parameters and HOMO- LUMO Gap energy were calculated. Results frombinding energies indicate that it is possible thermodynamically to bind Clonidine drug to SWCNT.The calculated NMR p...
