Nonlinear optical chromophores containing a novel pyrrole-based bridge: optimization of electro-optic activity and thermal stability by modifying the bridge
sunshine: Two new pyrrole‐containing organicdyes were rationally designed and easily prepared. Thanks to the special electronic properties of pyrrole moieties and the introduction of the non‐coplanar aromatic rings through a single bond (blue part in the above structure), a solar‐cell device based on the sensitizer LI‐1 yields an overall conversion efficiency as high as 91 % of the standard cell from N719
