Absorption Tuning of Monosubstituted Triazatruxenes for Bulk Heterojunction Solar Cells
摘要:
A series of triazatruxene (TAT)-functionalized Bodipy dyes were prepared by a sequence of reactions involving either cross-coupling reactions promoted by Pd complexes or a Knoevenagel reaction leading to a vinyl linker. The new dyes show large absorption coefficients and fluorescence quantum yields as well as interesting electrochemical properties. The blue dyes of this series exhibit interesting photovoltaic effects (V-oc = 0.83 V, J(sc) = 3.6 mA/cm(2), efficiency 0.9%) in bulk heterojunction solar cells, due to the good hole mobility imported by the TAT entity.
Depending on the structure of the substituent at the nitrogen atom of the heterocycle, reaction of isoindigo derivatives with hydrazine hydrate leads to the formation of either oxindole derivatives, or to a substituted isatin-3-hydrazone.
