Surface Modification Using Trip-C12' for Performance Improvement of OFET
Surface treatment of insulator is one of the most reliable technique for an improvement of performance of organic field effect transistor (OFET). TCI offers Trip-C12' [D5881], a tripodal triptycene with dodecyloxy groups at 1-, 8- positions and methoxy group at 13- position. Trip-C12' can modify the target surface regardless of the type of substrate, because the highly oriented structure is caused by its own unique self-assembling ability rather than by chemical bonding with the substrate. TCI has demonstrated and evaluated that the mobility of the OFETs can be increased by inserting the Trip-C12' layers.
(6,6)Carbon Nanobelt as a Useful Synthetic Tool for the Construction of Cycloiptycenes
Iptycenes have a structure in which aromatic ring is condensed into a bicyclooctatriene skeleton, as represented by triptycene. As a rigid three-dimensional π-conjugated molecule group, they form attractive target molecules. However, it is not easy to synthesize iptycenes from available small molecules. In particular, cycloiptycene, in which triptycene is condensed to form a ring shape, has never been synthesized. Segawa, Itami and co-workers have succeeded in the synthesis of each of the cycloiptycene derivatives in one step from (6,6)carbon nanobelt [I1078]. It is reported that (6,6)carbon nanobelt react as a diene in the Diels–Alder reaction with arynes and alkynes like diphenylacetylene.
Self-Assembled Monolayer Forming Reagent Enabling High Performance Organic Thin-Film Solar Cell
2PACz [C3663] can form a self-assembly monolayer (SAM) on metal oxide surfaces due to the functionality of its terminal phosphonic acid moiety. 2PACz enhances efficiency, stability, and cost-effectiveness of perovskite solar cells. As a result, the 2PACz-based device shows better performance over the one using PTAA hole transport material. Recently, 2PACz was further studied in organic thin-film solar cell (OPV), and improvements in power conversion efficiency and stability were observed when compared to the case of PEDOT:PSS. An OPV device with 2PACz-modified ITO electrode and the ternary BHJ (PM6:BTP-eC9:PC71BM) show a maximum PCE of 18.03%.
Visible light-induced photoreactions have been intensively developed, because a photoreaction under visible light does not require high energy UV light and the reactions occur under mild conditions avoiding formation of unexpected by-products. TCI offers many organocatalysts and metal complex catalysts like ruthenium and iridium-based complexes for the photoreactions. It is reported that the photoredox catalysts catalyzes Csp2-Csp3 bond formation, which is difficult to achieve with palladium catalysts. In addition, they are used as photoactivated co-catalysts for nickel-catalyzed ligand-free aryl amination.
