Photoswitching a molecular catalyst to regulate CO2 hydrogenation.
Dalton Trans. 44 , 14854-64, (2015) Inspired by nature's ability to regulate catalysis using physiological stimuli, azobenzene was incorporated into Rh(bis)diphosphine CO2 hydrogenation catalysts to photoinitiate structural changes to modulate the resulting catalytic activity. The rhodium bound... |

A charged aerosol detector/chemiluminescent nitrogen detector/liquid chromatography/mass spectrometry system for regular and fragment compound analysis in drug discovery.
J. Chromatogr. A. 1411 , 63-8, (2015) In this paper, we introduce a high throughput LCMS/UV/CAD/CLND system that improves upon previously reported systems by increasing both the quantitation accuracy and the range of compounds amenable to testing, in particular, low molecular weight "fragment" co... |

Rheological profiling of organogels prepared at critical gelling concentrations of natural waxes in a triacylglycerol solvent.
J. Agric. Food Chem. 63 , 4862-9, (2015) The aim of this study was to use a detailed rheological characterization to gain new insights into the gelation behavior of natural waxes. To make a comprehensive case, six natural waxes (differing in the relative proportion of chemical components: hydrocarbo... |

Photoisomerizable and thermoresponsive N-isopropylacrylamide-surfmer copolymer hydrogels prepared upon electrostatic self-assembly of an azobenzene bolaamphiphile.
Macromol. Rapid Commun. 34(5) , 393-8, (2013) Photoreactive and thermoresponsive N-isopropylacrylamide (NIPAM)-surfmer copolymer hydrogels containing 4,4'-di(6-sulfato-hexyloxy)azobenzene (DSHA) dianions are described. The functional hydrogels are obtained in a two steps. First a micellar aqueous solutio... |

Photoreversible switching of the lower critical solution temperature in a photoresponsive host-guest system of pillar[6]arene with triethylene oxide substituents and an azobenzene derivative.
J. Am. Chem. Soc. 134(49) , 20146-50, (2012) A new water-soluble thermoresponsive pillar[6]arene with triethylene oxide groups was synthesized. The pillar[6]arene showed lower critical solution temperature behavior in aqueous solution. Its clouding point was photoreversibly switched based on a photoresp... |

Effect of the steric molecular structure of azobenzene on the formation of self-assembled monolayers with a photoswitchable surface morphology.
Langmuir 29(14) , 4622-31, (2013) The growth processes of self-assembled monolayers (SAMs) of two azobenzene disulfides formed on flat gold surfaces were studied to confirm the effect of the intermolecular interactions between azobenzene molecules on the light-triggered surface morphologies o... |

The still unknown azobenzene - wavelength dependent photoanisotropy in amorphous azobenzene polymers.
Opt. Express 21(2) , 1812-9, (2013) We demonstrate a new type of anisotropy in thin films of amorphous azobenzene polymers induced between 570 and 633 nm, where the absorbance in the film is on the order of 0.05. The anisotropy has a pronounced radial contribution. This observation points to an... |

Azobenzene as photoresponsive conformational switch in cyclic peptides.
J. Pept. Res. 65(1) , 4-14, (2005) Over the last decades azobenzene has been the most widely used optical trigger for the synthesis of photoresponsive systems ranging from poly-alpha-amino acids to innovative materials with light-controlled mechanical and optical properties. More recently, its... |

Control over hierarchy levels in the self-assembly of stackable nanotoroids.
J. Am. Chem. Soc. 134(44) , 18205-8, (2012) We report a precise control over the hierarchy levels in the outstanding self-organization process shown by chiral azobenzene dimer 1. This compound forms uniform toroidal nanostructures that can hierarchically organize into chiral nanotubes under the control... |

Contactless, photoinitiated snap-through in azobenzene-functionalized polymers.
Proc. Natl. Acad. Sci. U. S. A. 110(47) , 18792-7, (2013) Photomechanical effects in polymeric materials and composites transduce light into mechanical work. The ability to control the intensity, polarization, placement, and duration of light irradiation is a distinctive and potentially useful tool to tailor the loc... |
