Modeling of Azobenzene-Based Compounds

Physical Sciences Reviews, 2017
AbstractAzobenzene is by far the most studied photochromic molecule and its applications range from optical storage to bio-engineering. To exploit the great potential of azobenzene, one must achieve deep understanding of its photochemistry as single molecule in solution AS WELL AS in-chain moiety and pendent group in macromolecular structures.

Pyridyl-substituted azobenzene disperse dyes

Dyes and Pigments, 1992
Abstract N,N-Disubstituted aminoazobenzene dyes containing a 2-pyridyl substituent were prepared and used for the dyeing, as disperse dyes, of polyamide, polyester and cellulose acetate. The dyeings and the fastness tests gave very satisfactory results.

Theoretical Study of the Isomerization Mechanism of Azobenzene and Disubstituted Azobenzene Derivatives

The Journal of Physical Chemistry A, 2006
A series of azobenzenes was studied using ab initio methods to determine the substituent effects on the isomerization pathways. Energy barriers were determined from three-dimensional potential energy surfaces of the ground and electronically excited states. In the ground state (S(0)), the inversion pathway was found to be preferred.

Athermal Azobenzene‐Based Nanoimprint Lithography

Advanced Materials, 2016
A novel nanoimprint lithography technique based on the photofluidization effect of azobenzene materials is presented. The tunable process allows for imprinting under ambient conditions without crosslinking reactions, so that shrinkage of the resist is avoided. Patterning of surfaces in the regime from micrometers down to 100 nm is demonstrated.

Azobenzene photoswitches in bulk materials

Physical Review E, 2008
A nonadiabatic two-scale quantum-classical dynamics method is developed to allow for dynamical simulation of photoinduced processes and reactions in chemically complex condensed-matter systems such as photosensitive liquid crystals. A first application to photoswitching of azobenzene in the bulk reveals not only valuable insights into the excited-state

Azobenzene-Linked Porphyrin−Fullerene Dyads

Journal of the American Chemical Society, 2007
A new group of porphyrin-fullerene dyads with an azobenzene linker was synthesized, and the photochemical and photophysical properties of these materials were investigated using steady-state and time-resolved spectroscopic methods. The electrochemical properties of these compounds were also studied in detail.
