The synthesis, spectral characterization, and electrochemical behavior of bis(tri-n-hexylsiloxy)(2,3-phthalocyaninato)silicon left bracket SiPc(OR)//2 right bracket , its dimer left bracket RO(SiPcO)//2R right bracket , and its naphthalocyanine analog left bracket SiNc(OR)//2 right bracket are described. All compounds show near-UV absorption corresponding to Soret and N bands and intense absorption in the visible - near-IR region corresponding to Q bands. In CH//2Cl//2, within the solvent stability limit, there are two reductions and one oxidation for SiPc(OR)//2 and two reductions and two oxidations for RO(SiPcO)//2R and SiNc(OR)//2; all appear as reversible one-electron waves, although n equals 2 for the dimer. The difference in the peak potentials of the first oxidation and first reduction waves agrees well with the excitation energy and fluorescence (corresponding to Q bands) of SiPc(OR)//2 and SiNc(OR)//2.
The impact of the extended π-conjugation in photophysical, photochemical and aggregation behavior of new phthalocyanine–naphthalocyanine hybrids

We report the synthesis and characterization of phthalocyanine–naphthalocyanine hybrids and the impact of the extended π-conjugation on the macrocycles aggregation, singlet oxygen production, fluorescence lifetime and quantum yields in solution. We observed that the addition of naphthalol units in the structure causes a bathochromic shift in UV-vis, emission and excitation bands and decreases the quantum yield of singlet oxygen in solution.
Iterative synthesis of acenes via homo-elongation

supporting information; experimental part, p. 803 - 805 (2009/07/10)
Starting from aromatic ortho-dialdehydes, we devised a homo-elongation protocol that combines a Wittig olefination and subsequent intramolecular Knoevenagel condensation to produce acene diesters and dinitriles. The Royal Society of Chemistry.
