MALEIMIDE-BASED COMPOUND, AND TAUTOMER OR STEREOISOMER THEREOF, DYE FOR PHOTOELECTRIC CONVERSION, AND SEMICONDUCTOR ELECTRODE, PHOTOELECTRIC CONVERSION ELEMENT AND PHOTOELECTROCHEMICAL CELL USING THE SAME
Two unsymmetricalsquaraines, where the electron-rich 3,4-ethylenedioxythiophene or bithiophene conjugated fragment was used to link unconventionally the squaraine core and the hexyloxyphenyl amino group, were applied for DSCs. The corresponding photovoltaic devices exhibit an attractively panchromatic response and also convert a portion of the near-infrared photons into electricity.
The present invention discloses organic and inorganic photosensitizer dyes as the following formulas (1) to (3), wherein the substituents “A, B, D and G” are as defined in claim

key-reaction: Stille cross-couplings. This requires tedious prefunctionalizations including the preparation and treatment of unstable organolithium and toxicity-concern organotin reagents. In contrast to traditional multistep synthesis, this work describes that a series of star-shaped small molecules with a carbazole or phenothiazine core can be efficiently synthesized through a shortcut using optimized direct
