Asym. magnesium tetraethynylporphyrin derivatives bearing two diketopyrrolopyrrole (DPP) units and two different aryl units were synthesized by multistage Sonogashira coupling reactions. According to saturated UV-Vis-NIR spectra, the solubility of the asym. porphyrin derivatives was superior to that of sym. porphyrin derivatives Frontier orbital energies were investigated in the solution state by differential pulse voltammetry and in the solid state by photoelectron yield spectroscopy and UV-Vis-NIR spectroscopy. Time-dependent d. functional theory calculations were carried out to simulate the UV-Vis-NIR absorption spectra and revealed splitting of the Q band into two bands at 712 nm and 650 nm. The thickness of active layers in solution-processed organic solar cells was influenced by the solubility of the porphyrin derivatives When the compound with the highest solubility was used (2d), the film thickness was 215 nm, which is larger than-the thickness of ∼120 nm reported for sym. porphyrin derivatives Also, the short-circuit c.d. (JSC) was influenced by solubility, especially for compound 2d, compared with other asym. compounds 2a-c. The optimized device conditions using 2d and PC61BM gave JSC of 14.86 mA/cm2, open-circuit voltage of 0.69 V, fill factor of 0.47, and power conversion efficiency of 4.84%. In the experimental materials used by the author, we found Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3COA of Formula: C51H42O3Pd2)
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is used in the preparation of semiconducting polymers processed from nonchlorinated solvents into high performance thin film transistors.COA of Formula: C51H42O3Pd2 It is also used in the synthesis of polymer bulk-heterojunction solar sells as a semiconductor.
