A new series of azobenzene-bridged metal-free organic dyes and application on DSSC

A series of novel azobenzene-based dyes were designed and synthesized using azobenzene as the π-spacer unit to connect diarylamino and cyanoacetic acids for construction of the D–π–A conformation. The introduction of a thienyl into the anchor group (A) co

Creation of azobenzene-based photochromic amorphous molecular materials - Synthesis, glass-forming properties, and photochromic response

A novel family of azobenzene-based photochromic amorphous molecular materials has been created. They were found to readily form amorphous glasses with well-defined glass-transition temperatures and to exhibit photochromism as amorphous films as well as in solution. It was found that their quantum yields of trans-cis photoisomerization were smaller as amorphous films than in solution and that the backward cis-trans thermal isomerization reactions as amorphous films were either accelerated or retarded relative to those in solution, depending upon their molecular structures. In addition, the rate acceleration for the cis-trans thermal isomerization as amorphous films relative to solution was found to be more prominent as the irradiation time for generating the cis-isomer became shorter.
