Utilization of the renewable solar fuel based on a perylenetetracarboxylic acid diimide (PTCDI)–semiconductor composite represents an effective method to solve the energy crisis; however, most applications have focused on dye sensitization of the monomolecular layer. Here the synergy effect of PTCDI self-assembly and P25 nanoparticles (NPs) has been elucidated systematically from the PTCDI stacking structure on P25 NP and electron transfer (ET) mode, for which the visible-light photocatalytic activity of PTCDI self-assembly through the assistance of P25 has been acquired and enhanced, even up to 7 times with the addition of EDTA. It has been found that self-assembly of PTCDI nanowires (NWs) as building blocks has been reconstructed on P25 NP via arrangement of short-range π–π stacking that is important for high photocatalytic activity. We inferred that the indentation plays a key role in the formation of the short-range π–π stacking mode on the basis of the results of XRD, photoluminescence, transient decay spectroscopy, and photocurrent measurements. In addition to that, a substantial part of the electrons excited in the interfacial layer of the PTCDI shell are injected into the conduction band of P25, thus preventing charge recombination. Our findings will provide guidance for photocatalytic enhancement of the organic self-assembly.

Photophysical Characterization, Two-Photon Absorption and Optical Power Limiting of Two Fluorenylperylene Diimides

et al. 2008

Perylene diimides have unique optical and electronic properties and have attracted interest in fields ranging from nonlinear optics to photovoltaics. The steady-state linear photophysical properties, two-photon absorption (2PA) spectra, and optical limiting behavior of fluorenylperylene diimide-based derivatives were investigated in solution at room temperature. An efficient intramolecular energy transfer and specific strong dependences of fluorescence quantum yield on solvent properties were observed. The 2PA spectra were measured over a broad spectral region by two-photon induced fluorescence and open aperture Z-scan methods under femtosecond and picosecond excitation, respectively. The maximum values of pure 2PA cross sections, up to ∼3500 GM, were obtained for fluorenylperylene diimide-based derivatives under picosecond excitation, when excited-state absorption and stimulated emission processes were taken into account. These perylene derivatives exhibited efficient two-photon optical power limiting under picosecond excitation.

Water‐soluble diblock copolymer, poly(N‐isopropylacrylamide)‐block‐poly(N‐vinyl‐2‐pyrroridone) (PNIPAMm‐b‐PNVPn), was found to associate with fullerene (C60), and thus C60 can be solubilized in water. The 63C60/PNIPAMm‐b‐PNVPn micelle formed a core‐shell micelle‐like aggregate comprising a C60/PNVP hydrophobic core and a thermoresponsive PNIPAM shell. The C60‐containing polymer micelle formation and its thermoresponsive behavior were characterized using light scattering and 1H NMR techniques. The hydrodynamic radius (Rh) of the C60‐bound polymer micelle increased with increasing temperature, which was ascribed to the hydrophobic association between dehydrated PNIPAM shells above lower critical solution temperature (LCST). 1H NMR data suggest that the motion of the PNIPAM block is restricted above LCST due to the dehydration of the PNIPAM shell in water. The generation of singlet oxygen by photosensitization by the C60‐bound polymer micelle was confirmed from photooxidation of 9,10‐anthracenedipropionic acid. Furthermore, DNA was found to be cleaved by visible light irradiation in the presence of the C60‐bound polymer micelle. Therefore, there may be a hope for a pharmaceutical application of the C60‐bound polymer micelle to cancer photodynamic therapy. © 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2011.
