  Substituted hydroquinones and quinones and methods of synthesizing such compounds are disclosed herein. The substituted hydroquinones have the formula: while the substituted quinones have the corresponding oxidized structure (1,4-benzoquinones). One, two, three, or all four of R1, R2, R3 and R4 comprise a thioether moiety and a sulfonate moiety, and wherein each R1, R2, R3 and R4 that does not comprise a thioether and a sulfonate moiety sulfonate moiety is independently a hydrogen, an alkyl or an electron withdrawing group. The substituted hydroquinones and quinones are soluble in water, stable in aqueous acid solutions, and have a high reduction potential in the oxidized form. Accordingly, they can be used as redox mediators in emerging technologies, such as in mediated fuel cells or organic-mediator flow batteries.

• Polyimide and Imide Compound Exhibiting Bright Red Fluorescence with Very Large Stokes Shifts via Excited-State Intramolecular Proton Transfer

  DOI：10.1021/ma502456f

  日期：2015.3.24

  A novel polyimide (PI) emitting a prominent red fluorescence was prepared based on 3,6-dihydroxypyromellitic dianhydride (P2HDA) and 4,4'-diaminocyclohexylmethane (DCHM). In order to investigate the fluorescence properties of the PI, an imide model compound, N,N'-dicyclohexyl-3,6-dihydroxypyromellitimide (P2H-Ch), corresponding to one repeating unit of the PI, was also synthesized. The UVvis absorption and fluorescence spectra of P2H-Ch in CHCl3 and the solid PI film demonstrated intense red fluorescence at around 640 nm with a very large Stokes shift (nu) of 7655 and 8994 cm(-1), respectively, via the excited-state intramolecular proton transfer (ESIPT). Moreover, the corresponding monoanion and dianion species were formed in basic conditions with an organic base (DBU) and basic salt (NaOH), which were characterized by highly visible halochromism. The introduction of -OH groups into the pyromellitic moiety of imide compounds or PIs at their para positions led to the long-wavelength fluorescent emission as well as to the high pH sensitivity.
