Nitrogen-15 labeled butyl 4,5,6,7-tetrahydro-2H-isoindole-1-carboxylate was prepared via butyl isocyanoacetate from 15N-glycine in an overall 46% yield, This bicyclic intermediate was converted into nitrogen-15 and carbon-13 labeled 2,3:7,8:12, 13:17, 18-tetrabutanoporphyrin, a useful model system for the sedimentary tetrahydrobenzoporphyrins.

A novel class of dyes, namely benzoporphyrins, was synthesized and implemented into dye-sensitized solar cells. They feature complementary absorptions compared to N719, which renders them promising candidates for co-sensitization in DSSCs. Notably, metallated benzoporphyrins reveal a TiO2-nanoparticle attachment that is size and aggregation dependent. Therefore, unproductive energy-transfer events between the selectively attached dyes can be prevented. In light of the latter, an efficiency improvement of 39 % has been achieved upon selective adsorption of benzoporphyrins and N719 onto different layers of TiO2 photoelectrode.

Two series of copper tetraarylporphyrins containing β,β′-fused tetrabutano or tetrabenzo groups were synthesized and characterized as to their electrochemistry and spectroelectrochemistry in nonaqueous media. The examined compounds are represented as butano-(TpYPP)CuII and benzo-(TpYPP)CuII, where TpYPP is the porphyrin dianion and Y is a CH3, H or Cl substituent on the para-position of the four meso-phenyl rings of the compound. Each neutral porphyrin in the two series is ESR active and shows a typical d9 Cu(ii) signal in frozen CH2Cl2 solution. Each Cu(ii) porphyrin also undergoes two reversible one-electron reductions and two reversible one-electron oxidations in DMF or CH2Cl2 containing 0.1 M tetra-n-butylammonium perchlorate to give a π-anion radical and dianion upon reduction and a π-cation radical and dication upon oxidation. A third one-electron oxidation is also observed for butano-(TpYPP)Cu (Y = CH3 and H) and benzo-(TPP)Cu in PhCN and this process is assigned to the CuII/CuIII transition. The reversible half-wave potential for the first oxidation of each compound in both series is shifted negatively by about 500 mV as compared to E1/2 values for oxidation of the related copper tetraarylporphyrin without the four fused benzo or butano rings while smaller positive shifts of 60 and 300 mV are seen for reduction of the tetrabenzotetraarylporphyrins and tetrabutaotetraarylporphyrins, respectively, as compared to the same redox reactions of the related tetraarylporphyrins. The electrochemically measured HOMO-LUMO gap averages 1.76 ± 0.05 V for benzo-(TpYPP)CuII, 2.04 ± 0.06 V for butano-(TpYPP)CuII and 2.33 ± 0.03 for (TpYPP)Cu in CH2Cl2.
