Insights into a novel class of azobenzenes incorporating 4,6- O -protected sugars as photo-responsive organogelators
A novel class of 4,6-O-butylidene/ethylidene/benzylidene β-d-glucopyranose gelator functionalized with photo-responsive azobenzene moieties were designed and synthesized and also characterized using different spectral techniques. These azobenzene-based or

Oligoazobenzenes - Switching in a new dimension
A new synthesis of cyclotrisazobenzene with different substituents was developed with yields of up to 30%. Solid-state structures of cyclotrisazobenzene as well as the tert-butyl derivative were obtained. Also, the photochromic properties and the complexa

Synthesis and property studies of cyclotrisazobenzenes
Azobenzenophanes are fascinating macrocycles, which are of special interest due to their unique photochromic behavior. Cyclotrisazobenzenes 2 (R = H, Br, tBu) were prepared to probe how much strain the photoisomerization of the azobenzene motive can tolerate. The macrocycles were synthesized in an overall yield of 10-20% from oriho-phenylenediamine (6). Solid-state structures of cyclotrisazobenzenes 2a and 2b were obtained. Irradiation under various conditions did not induce any isomerization.
