The UV-vis-NIR absorption spectrum of3exhibits two major bands at 795 and 895 nm in the near-IR region, while2shows maximum absorbance at 661 nm and strong fluorescence at 692 nm (ΦF= 0.59). The cyclic voltammetry of3consists of two pairs of reversible one-electron reductions at -0.61...
Conditions which abolish O 2 evolution and remove functional manganese destroy this effect. The spectrum and absorptivity of the oscillating component are similar to those found in synthetic manganese dimers poised in the mixed-valent oxidation state Mn 2(III,IV). A similar structural unit is thus...
Note that the discussed P+HL− and P+QA− spectra are EADS, resulting from the global analysis, whereas only the P+BL− spectrum is SADS as resolved in the target analysis. Whereas the CO modes of BChl and BPhe pigments upshift in the cation state, they downshift in both the excite...

benzoquinonefluorescencenear-IRredox activeA near-infrared absorbing boron-dipyrromethene (BODIPY) chromophore coupled with two benzoquinone moieties at its 3,5-positions, 3, was prepared via Knoevenagel condensation of 1,3,5,7-tetramethyl-8-(4'-benzonitille) BODIPY 1 with 3,5-di-tert-butyl-4-...
The infrared and Raman spectra of some chloroquinones have been obtained and compared with the spectrum of para benzoquinone. Vapour, solution and crystal phase data are presented. The complete vibrational assignment of p-benzoquinone has been made [1], and this has been used to aid the ...
