Photoinduced electron transfer and charge separation in anthraquinone-substituted porphyrin–phthalocyanine heterodimer

A one-dimensional inorganic–organic hybrid compound:catena-poly[ethylenediammonium [indate(III)-di-μ-hydrogenphosphato(V)-μ-hydroxido] monohydrate]

“…The terminal O atoms are involved in strong hydrogen bonds (see below) which likewise explains their low bond valence sum. These results are in good agreement with the framework formula and are in close agreement with those reported in the literature for similar indium phosphates (Li et al 2006;Du et al 2004). …”

Heterothiometallic polymeric clusters

“…Other S-bridging examples include the saddle aggregate o2 [11], the hexagonal prism-shaped dimer o3 [3b], the mixed-polymerizing cluster o4 [12], the eight nuclear square o5 [13], and the eicosanuclear cluster o6 [14]. The square monomer m11 share peripheral X bridges to form the dimer o7 [15], and the nest shaped monomer m7 partakes the outer iodide bridges to form the dimer o8 [16].…”

Porphyrin-anthraquinone dyads: Synthesis, spectroscopy and photochemistry

“…[9][10][11] Many current investigations are concerned with porphyrin-quinone molecules in order to understand the role of factors like distance, orientation, energetics and medium in determining the rate of intramolecular photoinduced electron transfer (PET). [12][13][14][15][16][17][18][19][20][21] The nature of the bridge linking the D and A components is also a subject of much interest since PET in many donor-acceptor (D-A) molecules is known to be dominated by through-bond interactions. 3 As part of our continuing interest in studies of PET processes, we report here the design, synthesis, spectral (UV-visible, IR, FAB-MS, 1 H NMR and ESR) and electrochemical characterization and, more importantly, the photophysical properties of an azomethine-bridged porphyrin-anthraquinone dyad (H 2 L 2 ) and its copper(II) (CuL 2 ) and zinc(II) (ZnL 2 ) derivatives (figure 1).…”
