Wisely Designed Phthalocyanine Derivative for Convenient Molecular Fabrication on a Substrate
An
axial-substituted silicon phthalocyanine derivative, SiPcÂ(OR)<sub>2</sub> (R = C<sub>4</sub>H<sub>9</sub>), that is soluble in organic
solvent is conveniently synthesized. This silicon phthalocyanine derivative
reacts with a hydroxyl group on a substrate and then with another
phthalocyanine derivative under mild conditions. The accumulation
number of the phthalocyanine molecules on the substrates is easily
controlled by the immersion time. On the basis of AFM (atomic force
microscopy) images, the surface of the phthalocyanine-modified glass
substrate has uneven structures on the nanometer scale. ITO electrodes
modified with the composition of the phthalocyanine derivative and
PCBM show stable cathodic photocurrent generation upon light irradiation
Potential Tuning of Nanoarchitectures Based on Phthalocyanine Nanopillars: Construction of Effective Photocurrent Generation Systems
Nanopillars
composed of a photoresponsive phthalocyanine derivative have been
conveniently fabricated using a continuous silane coupling reaction
on a substrate. The chemical potentials of phthalocyanine nanopillars
(PNs) are precisely controlled by changing the number of phthalocyanine
derivatives on the substrate. In addition, photocurrent generation
efficiencies have been strongly influenced by the number of phthalocyanine
derivatives. High photocurrent conversion cells in a solid state have
been obtained by the combination of PNs and a fullerene derivative
