Abstract

We report a study on the excited state dynamics of two symmetric squaraine dyes, carrying different side-groups attached to the squaric ring. By means of UV-VIS absorption and time-resolved fluorescence spectroscopies, we found that the photodynamic of these functional molecules depends strongly on both the steric and electro-donating properties of the side-group.
