Rieke Metals Announces New Monomers
Rieke Metals has added new monomers to their product portfolio! These monomers are ideal in use of perovskite solar cells, organic semiconductors and UV photodetectors.
New item 4163, 1,4-Dibromo-2,5-dihexyloxybenzene, emphasizes the superior role of alkyl groups over ethylene glycol in the design of hole-transporting conjugated polymers for perovskite solar cells. While a (2-methoxyethoxy)ethoxy side chain, offers enhanced flexibility and results in higher hole mobility at the same hole density, the hexyloxy, demonstrates a stronger electron-donating ability which leads to higher hole density and better conductivity under identical processing conditions.
Items 4164, 2,2′-[2,5-Bis(hexyloxy)-1,4-phenylene]bis[thiophene] aka BHBT and 4165, 5,5”-[2,5-Bis(hexyloxy)-1,4-phenylene]bis[2,2′-bithiophene] aka BHBT2, have been utilized for multiple applications including organic/polymeric semiconductors and organic ultraviolet photodetectors. Structural and photoelectrical characteristics are well described for these compounds as thin films and components in bulk-heterojunction and composite nanotubes.
NEW
With the use of BHBT2 in UV photodetectors, the photodetector showed a fast, reversible, and stable response with very high detectivity. The determination that there was efficient UV detection was partly attributed to the strong absorption of BHBT2 in the UV region.
Improving the intramolecular noncovalent interactions of organic devices is critical. Addition of BHBT2 has been shown as an important way to modulate the optoelectronic performances of organic photoconductors.
