Therefore, control of the chromophore density is essential for enhancing and manipulating the photoisomerization yield. We systematically compare two methods to achieve this goal: First, we assemble monocomponent azobenzene–alkanethiolate SAMs on gold nanoparticles of varying size. Second, we form mixed SAMs of azobenzene–alkanethiolates and “dummy” alkanethiolates on planar substrates. Both methods lead to a gradual decrease of the chromophore density and enable efficient photoswitching with low-power light sources. X-ray spectroscopy reveals that coadsorption from solution yields mixtures with tunable composition. The orientation of the chromophores with respect to the surface normal changes from a tilted to an upright position with increasing azobenzene density. For both systems, optical spectroscopy reveals a pronounced excitonic shift that increases with the chromophore density. In spite of exciting the optical transition of the monomer, the main spectral change in mixed SAMs occurs in the excitonic band. In addition, the photoisomerization yield decreases only slightly by increasing the azobenzene–alkanethiolate density, and we observed photoswitching even with minor dilutions. Unlike in solution, azobenzene in the planar SAM can be switched back almost completely by optical excitation from the cis to the original trans state within a short time scale. These observations indicate cooperativity in the photoswitching process of mixed SAMs.' article_processing_charge: No article_type: original author: - first_name: Thomas full_name: Moldt, Thomas last_name: Moldt - first_name: Daniel full_name: Brete, Daniel last_name: Brete - first_name: Daniel full_name: Przyrembel, Daniel last_name: Przyrembel - first_name: Sanjib full_name: Das, Sanjib last_name: Das - first_name: Joel R. full_name: Goldman, Joel R. last_name: Goldman - first_name: Pintu K. full_name: Kundu, Pintu K. last_name: Kundu - first_name: Cornelius full_name: Gahl, Cornelius last_name: Gahl - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn - first_name: Martin full_name: Weinelt, Martin last_name: Weinelt citation: ama: Moldt T, Brete D, Przyrembel D, et al.

However, relatively little attention has been devoted to how the shape and surface chemistry of magnetic nanoparticles affects their self-assembly properties. Here, we undertook a combined experiment–theory study aimed at better understanding of the self-assembly of cubic magnetite (Fe3O4) particles. We demonstrated that, depending on the experimental parameters, such as the direction of the magnetic field and nanoparticle density, a variety of superstructures can be obtained, including one-dimensional filaments and helices, as well as C-shaped assemblies described here for the first time. Furthermore, we functionalized the surfaces of the magnetic nanocubes with light-sensitive ligands. Using these modified nanoparticles, we were able to achieve orthogonal control of self-assembly using a magnetic field and light. article_processing_charge: No article_type: original author: - first_name: Gurvinder full_name: Singh, Gurvinder last_name: Singh - first_name: Henry full_name: Chan, Henry last_name: Chan - first_name: T. full_name: Udayabhaskararao, T. last_name: Udayabhaskararao - first_name: Elijah full_name: Gelman, Elijah last_name: Gelman - first_name: Davide full_name: Peddis, Davide last_name: Peddis - first_name: Artem full_name: Baskin, Artem last_name: Baskin - first_name: Gregory full_name: Leitus, Gregory last_name: Leitus - first_name: Petr full_name: Král, Petr last_name: Král - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Singh G, Chan H, Udayabhaskararao T, et al.

Recently, choosing the nitric oxide molecule as an example, we have introduced and demonstrated an experimental approach to measure coupled valence electronic and rotational wave packets using high-order-harmonic-generation (HHG) spectroscopy [Kraus et al., Phys. Rev. Lett. 111, 243005 (2013)]. A short outline of the theory to describe the combination of the pump and HHG probe process was published together with an extensive discussion of experimental results [Baykusheva et al., Faraday Discuss. 171, 113 (2014)]. The comparison of theory and experiment showed good agreement on a quantitative level. Here, we present the theory in detail, which is based on a generalized density-matrix approach that describes the pump process and the subsequent probing of the wave packets by a semiclassical quantitative rescattering approach. An in-depth analysis of the different Raman scattering contributions to the creation of the coupled rotational and electronic spin-orbit wave packets is made. We present results for parallel and perpendicular linear polarizations of the pump and probe laser pulses. Furthermore, an analysis of the combined rotational-electronic density matrix in terms of irreducible components is presented that facilitates interpretation of the results. article_number: '023421' article_processing_charge: No article_type: original author: - first_name: Song Bin full_name: Zhang, Song Bin last_name: Zhang - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: Peter M. full_name: Kraus, Peter M. last_name: Kraus - first_name: Hans Jakob full_name: Wörner, Hans Jakob last_name: Wörner - first_name: Nina full_name: Rohringer, Nina last_name: Rohringer citation: ama: Zhang SB, Baykusheva DR, Kraus PM, Wörner HJ, Rohringer N.
