A Bench-Stable Antiaromatic Porphyrinoid Complex
Ni(II) meso-dimesitylnorcorrole [N1236] is a 16π-electron antiaromatic porphyrinoid complex which is bench-stable unlike many other antiaromatic compounds. It has been demonstrated that N1236 is a promising candidate as an electrode active material for rechargeable batteries, because of its reversible two-electron oxidation and two-electron reduction giving its aromatic dicationic and dianionic species, respectively. Moreover, there is an increased interest in exploring properties of not only N1236 but also its related compounds, such as the synthesis of pyridine-fused bis(norcorrole) derivatives using N1236 as a starting material.
Phenylphenothiazine (PTH) Derivatives
Phenylphenothiazine (PTH) is one of the key components in organic semiconductors, tha serves as both a hole transporting material for solar cells and an organic lectroluminescent material. Additionally, it has attracted attention as an organic photocatalyst and a catalyst for organic atom transfer radical polymerization (O-ATRP). TCI offer 4 products, 10-phenylphenothiazine [P2470], 10-(4-bromophenyl)phenothiazine [B5374], 10-(4-methoxyphenyl)phenothiazine [M3639] and 12-phenyl-12H-benzo[b]phenothiazine [P3081].
Electron Transport Material for OLED: NBPhen
NBPhen [D5581] is an electron transport material with high electron mobility (4.2 × 10-4 cm2/Vs). The HOMO and LUMO of NBPhen are -5.8 eV and -2.6 eV, respectively. NBPhen has also been reported to be used as an exciplex host.
Hole Transport Material: Spiro-OMeTAD
Spiro-OMeTAD [T3672] can be used as a hole transport material for perovskite solar cells, perovskite EL devices, dye-sensitized solar cells, and organic EL devices, etc. Spiro-OMeTAD is suitable for solution processes in device fabrication. It has been reported that The HOMO and LUMO of Spiro-OMeTAD are -5.0 eV and -1.5 eV, respectively (by photoemission spectroscopy).Upcoming Events
