Cyclic Azobenzene‐BODIPY Hybrids

Chemistry – A European Journal, 2023
AbstractCyclic azobenzene‐BODIPY hybrids were synthesized via cyclization by 1) acid‐catalysed condensation of azobenzene‐bridged dipyrroles with 3,5‐di‐tert‐butylbenzaldehyde, 2) oxidation with DDQ, and 3) metalation with BF3 ⋅ Et2O. The structures of many cyclic hybrids have been confirmed by single crystal X‐ray analysis.

Photoresponsive Dendritic Azobenzene Peptides

ChemBioChem, 2001
Two dendritic peptides containing a branched lysine core and up to eight azobenzene moieties in the periphery were synthesized on solid support employing the omega-amino acid 4-(aminomethyl)phenylazobenzoic acid. With an additional peptidic tail consisting of an oligolysine portion, water solubility was achieved for the dendrimers, which allowed for ...

Mechano-isomerization of azobenzene

Chemical Communications, 2013
We show that ultrasound-induced mechanical force isomerizes an azobenzene centered within a poly(methyl acrylate) polymer from cis to trans configuration without cleaving the azo bond. The isomerization rate was not altered by the polarity of the solvent indicating that the isomerization occurs through a non-polar, inversion transition state.

Azobenzene photoswitches for biomolecules

Chemical Society Reviews, 2011
The photoisomerization of azobenzene has been known for almost 75 years but only recently has this process been widely applied to biological systems. The central challenge of how to productively couple the isomerization process to a large functional change in a biomolecule has been met in a number of instances and it appears that effective photocontrol

Enthalpies of formation of cis-azobenzene and trans-azobenzene

The Journal of Chemical Thermodynamics, 1992
The standard (p° = 0.1 MPa) molar enthalpy of formation of crystalline trans-azobenzene was determined from its enthalpy of combustion in oxygen at 298.15 K measured by static-bomb calorimetry. The enthalpy of isomerization: ΔisomH°m(cr, cis → trans)/(kJ · mol−1) = -(49.1 ± 1.0), was measured by reaction-solution calorimetry: the isomerization was ...

The azobenzene derivatives

SPIE Proceedings, 2015
Azobenzene derivatives constitute a group of dyes which have photochromic properties and have been investigated as promising systems for diverse applications in the unconventional optic area, their properties can be moulded with help of light.
