A series of benzodipyrrolidone-based dimeric aza-BODIPY dyes with a pushâpull structure are synthesized. Single crystal X-ray diffraction demonstrates these extended aza-BODIPY dyes are planar. The resulting aza-BODIPY chromophores exhibit intense absorption in the 450â800 nm regions and possess lower-lying LUMO energy levels. Furthermore, the pushâpull substituents on aza-BODIPYs core have a positive effect on their optophysical properties.
This disclosure relates to novel organic dye and a method for preparing the same. The dye compound of the present invention, when used for a dye-sensitized solar cell (DSSC), shows improved molar absorption coefficient, J
sc
(short circuit photocurrent density) and photoelectric transformation efficiency, compared to dyes of the prior art, thus largely improving solar cell efficiency, and it may be purified without expensive column thus remarkably lowering dye synthesis cost.
Five sorts of soluble oligothiophenes containing 3,4-ethylenedioxythiophene (EDOT) were synthesized, and their optical and electrochemical properties were investigated.
