Reference of Bis(4-methoxyphenyl)amineIn 2019 ,《Synthesis, photophysical and electronic properties of tetra-donor- or acceptor-substituted ortho-perylenes displaying four reversible oxidations or reductions》 was published in Chemical Science. The article was written by Merz, Julia; Steffen, Andreas; Nitsch, Joern; Fink, Julian; Schuerger, Claudia B.; Friedrich, Alexandra; Krummenacher, Ivo; Braunschweig, Holger; Moos, Michael; Mims, David; Lambert, Christoph; Marder, Todd B.. The article contains the following contents:
(DPA)4-Per I and (Bmes2)4-Per II derivatives were synthesized via regioselective Ir-catalyzed C-H borylation and subsequent reactions, a strong π-donors and acceptors at the 2,5,8,11-positions of perylene were introduced leading to unusual properties. Thus, incorporation of four donor diphenylamine (DPA) or four acceptor Bmes2 (mes = 2,4,6-Me3C6H2) moieties yielded novel compounds which can be reversibly oxidized or reduced four times, resp., an unprecedented behavior for monomeric perylene derivatives Spectroelectrochem. measurements showed NIR absorptions up to 3000 nm for the mono-cation radical of II and a strong electronic coupling over the perylene bridge was observed indicative of fully delocalized Robin-Day Class III behavior. Both derivatives I and II possess unusually long intrinsic singlet lifetimes (τ0), e.g., 94 ns for the former one. The compounds I and II were emissive in solution, thin films, and the solid state, with apparent Stokes shifts were exceptionally large for perylene derivatives Transient absorption measurements on II revealed an addnl. excited state, with a long lifetime of 500μs, which sensitized singlet oxygen effectively.
