TL;DR: In this article, a new heterobimetallic complex [Mo(μ-Cl)(SnCl 3 )(CO) 3 (η 4 -NBD)] ( 1 ) has been prepared by reaction of [(CO) 4 Mo(μCl) 3 Mo(snCl 3 ]( CO) 3 ] with norbornadiene (NBD) at room temperature.

TL;DR: In this paper, a racemic 5,12-DiHETE-8,9-cyclopentadiene Diels-Alder adduct was prepared by palladium-catalyzed ternary coupling between vinylic halide, a vinyric tin compound, and norbonadiene in good yields.

TL;DR: It is demonstrated that the anchored CNBD monolayer remains operational and can be photo-converted to its energy-rich counterpart 2-cyano-3-(4-carboxyphenyl)quadricyclane (CQC).
Abstract: Molecular photoswitches provide an extremely simple solution for solar energy conversion and storage. To convert stored energy to electricity, however, the photoswitch has to be coupled to a semiconducting electrode. In this work, we report on the assembly of an operational solar-energy-storing organic-oxide hybrid interface, which consists of a tailor-made molecular photoswitch and an atomically-defined semiconducting oxide film. The synthesized norbornadiene derivative 2-cyano-3-(4-carboxyphenyl)norbornadiene (CNBD) was anchored to a well-ordered Co3O4(111) surface by physical vapor deposition in ultrahigh vacuum. Using a photochemical infrared reflection absorption spectroscopy experiment, we demonstrate that the anchored CNBD monolayer remains operational, i.e., can be photo-converted to its energy-rich counterpart 2-cyano-3-(4-carboxyphenyl)quadricyclane (CQC). We show that the activation barrier for energy release remains unaffected by the anchoring reaction and the anchored photoswitch can be charged and discharged with high reversibility. Our atomically-defined solar-energy-storing model interface enables detailed studies of energy conversion processes at organic/oxide hybrid interfaces.

TL;DR: The synthesis and conductance properties of a new type of robust molecular photothermal switch based on the norbornadiene–quadricyclane system are presented and the prevailing assumption that current will simply flow through the shortest through-bond path in a molecule is challenged.
Abstract: Integrating functional molecules into single-molecule devices is a key step toward the realization of future computing machines based on the smallest possible components. In this context, photoswitching molecules that can make a transition between high and low conductivity in response to light are attractive candidates. Here we present the synthesis and conductance properties of a new type of robust molecular photothermal switch based on the norbornadiene (NB)-quadricyclane (QC) system. The transport through the molecule in the ON state is dominated by a pathway through the π-conjugated system, which is no longer available when the system is switched to the OFF state. Interestingly, in the OFF state we find that the same pathway contributes only 12% to the transport properties. We attribute this observation to the strained tetrahedral geometry of the QC. These results challenge the prevailing assumption that current will simply flow through the shortest through-bond path in a molecule.
