In supercritical CO 2 , the photocatalytic oxidation of octanol appeared to follow pseudo-first-order kinetics, with octanal being produced as the initial product. At 309 K, the pseudo-first-order rate constant k d i s decreased upon increasing CO 2 pressure from 8 to 20 MPa, giving rise to an increased yield of octanal. When the temperature was raised within the range from 299 to 319 K at constant CO 2 pressure (10 MPa), k d i s increased while the net yield of octanal decreased. These changes are rationalized as being caused by changes in near-surface CO 2 density and, hence, in efficiency of mass transport of octanal to and from the catalytically active site. The observed dependence of the photoactivity of hydrophobic T805 TiO 2 in scCO 2 on temperature and pressure likely varies with surface conditions promoted by irradiation, which effects partial desilanization photocatalytically active sites. When scCO 2 density was very low, T805 TiO 2 did not suspend well into the scCO 2 fluid; that is, almost all of the T805 TiO 2 precipitated on a window or inner wall of the cell. At scCO 2 densities between 8 and 20 MPa, T805 TiO 2 was efficiently dispersed under stirring. At very low pressures near the critical point, the kinetic analysis was complicated by incident light scattering caused by suspended particles which act as inhibitory inner filters.}, number={29}, journal={JOURNAL OF PHYSICAL CHEMISTRY B}, author={Hirakawa, T and Whitesell, JK and Fox, MA}, year={2004}, month={Jul}, pages={10213–10218} }

The structures of these composites were established by TEM, elemental analysis, and 1 H NMR spectroscopy. Changes in optical and physical properties caused by attachment of the fluorenyl groups to the gold nanoparticles were studied by absorption, Fourier transform infrared, and fluorescence spectroscopies. Emission from the end-attached fluorenyl groups is substantially quenched upon attachment to a gold cluster so that less than 5% of emission intensity from an optically matched solution of the analogous freely dissolved fluorene and alkane-1-thiolate Au-MPCs is retained in the fluorenyl-alkane-1-thiolate Au-MPCs. Nanosecond flash photolysis shows that intersystem crossing (from the fluorenyl singlet to the corresponding triplet) was suppressed because energy transfer was much faster. No direct evidence of electron transfer from the excited fluorenyl group to the gold cluster could be observed, implying that electronic coupling through energy transfer accounts for most of the observed emission quenching and suppressed intersystem crossing.}, number={6}, journal={CHEMISTRY OF MATERIALS}, author={Gu, T and Whitesell, JK and Fox, MA}, year={2003}, month={Mar}, pages={1358–1366} }

In addition, the 6,6‘-dithio derivative (1,1‘,5,5‘-tetramethyl-6,6‘-dithio-3,3‘-bisverdazyl (7)) was prepared.

Film morphology is controlled by annealing of 250 nm thick films. Under these conditions, the degree of interchain interaction follows the degree of thermotropic liquid crystalline ordering which is, in turn, a function of the length of the attached alkyl substituents. Alkyl substituents also affect the solubility of these polymeric liquid crystals in organic solvents; low solubility favors strong ground state aggregation, as is evidenced by a red-shifted absorption band. In the annealed films, aggregate and excimer formation is evidenced by a broadening of the absorbance band, an increase in the intensity of the low energy emission, the appearance of new long-lived fluorescent species, and structure-dependent changes in observed fluorescence quantum yields.}, number={9}, journal={JOURNAL OF MATERIALS CHEMISTRY}, author={Teetsov, J and Fox, MA}, year={1999}, month={Sep}, pages={2117–2122} }

Virtually identical spectral behavior was observed whether the duplex was produced before deposition or by in situ complementary association. With a duplex bearing an appropriate pyrene end-label, the resulting thin film was photoresponsive. Surface emission measurements show no evidence for pyrene aggregation on the modified surfaces. The polarity of the photocurrent, reflecting photoinduced electron transfer initiated by photoexcitation of pyrene, is opposite that expected from the oligonucleotide-mediated reduction of the appended pyrene excited state.Key words: oligonucleotide, self-assembled monolayer, duplex formation, photoelectrochemistry, surface emission.}, number={5-6}, journal={CANADIAN JOURNAL OF CHEMISTRY-REVUE CANADIENNE DE CHIMIE}, author={Reese, RS and Fox, MA}, year={1999}, pages={1077–1084} }

Liquid crystalline phase stability, the identity of the inserted metal, and the nature of its supramolecular packing all influence the observed photoelectrochemical response. Porphyrin 2, which has a stable liquid crystalline phase, produces higher steady-state photocurrents than do the corresponding meso-substituted porphyrins 3 and 4, although liquid crystallinity is not an absolute requirement for observation of a photoresponse.

The resulting heterogeneous rate constants are compared to those known for the same reactions in homogeneous solution, where (SCN)2•- and I2•- were generated by pulse radiolysis. Relative to the solution phase, the reaction between (SCN)2•- and ascorbic acid on a TiO2 sol was accelerated by approximately a factor of 40, that between (SCN)2•- and hydroquinone was essentially unchanged, and that between (SCN)2•- and cysteine was slowed by approximately an order of magnitude.
