Azobenzene dye-coupled quadruply hydrogen-bonding modules as colorimetric indicators for supramolecular interactions

Beilstein Journal of Organic Chemistry, 2012
The facile coupling of azobenzene dyes to the quadruply hydrogen-bonding modules 2,7-diamido-1,8-naphthyridine (DAN) and 7-deazaguanine urea (DeUG) is described. The coupling of azobenzene dye 2 to mono-amido DAN units 4, 7, and 9 was effected by classic

Mechanism and Dynamics of Azobenzene Photoisomerization

Journal of the American Chemical Society, 2003
The excited-state dynamics of trans-azobenzene were investigated by femtosecond time-resolved photoelectron spectroscopy and ab initio molecular dynamics. Two near-degenerate pipi* excited states, S2 and S3,4, were identified in a region hitherto associated with only one excited state.

Biomineral‐Inspired Organic/Inorganic Colloidal Liquid‐Crystalline Hybrids for Photoresponsive Adhesion

Advanced Functional Materials, EarlyView.
A new class of photoresponsive liquid‐crystalline (LC) adhesives based on biomineral‐inspired organic/inorganic colloidal hybrids is reported. These colloidal LC materials are formed by hybridization of a hydroxyapatite nanorod with azobenzene‐based forklike molecules.
