The development of new strategies for the preparation of multicomponent supramolecular assemblies is a major challenge on the road to complex functional molecular systems. Here we present the use of a non-porous self-assembled monolayer from uC33-NDI-uC33, a naphthalenediimide symmetrically functionalized with unsaturated 33 carbon-atom-chains, to prepare bicomponent supramolecular surface systems with a series of alkoxy-pyrene (PyrOR) derivatives at the liquid/HOPG interface. While previous attempts at directly depositing many of these PyrOR units at the liquid/HOPG interface failed, the multicomponent approach through the uC33-NDI-uC33 template enabled control over molecular interactions and facilitated adsorption. The PyrOR deposition restructured the initial uC33-NDI-uC33 monolayer, causing an expansion in two dimensions to accommodate the guests. As far as we know, this represents the first example of a non-porous or non-metal complex-bearing monolayer that allows the stepwise formation of multicomponent supramolecular architectures on surfaces.

The metabolism of the four-ringed polycyclic aromatic hydrocarbon (PAH) pyrene was investigated using cell suspension cultures of soybean, wheat, purple foxglove, and jimsonweed and callus cultures of soybean and foxglove. In all species, nonextractable residues were found (soybean, jimsonweed, and foxglove suspensions, 14C; soybean and foxglove callus cultures, 20-25%; wheat, 30-40%); soluble metabolites were detected in only foxglove and wheat. About 90% of applied pyrene was transformed in wheat. Corresponding data from soybean and foxglove callus cultures were about 30% and those from soybean, jimsonweed, and foxglove suspensions about 7%. In foxglove, 1-hydroxypyrene methyl ether was identified as the main metabolite, whereas a complex mixture of carbohydrate conjugates of 1-hydroxypyrene was found in wheat. Due to the present results, crop and wild plants may be metabolic sinks for PAHs in the environment. Concentrations and toxicological implications of 1-hydroxypyrene, its derivatives, and analogous metabolites of other PAHs should be investigated.
Excited state intramolecular proton transfer in 1-hydroxypyrene

1-Hydroxypyrene (1) shows unusual acid'base chemistry in its singlet excited state. Whereas most hydroxyarenes experience a marked enhancement in their acidity when excited, and rapidly deprotonate to give the corresponding phenolate anion, this is not an important pathway for 1, despite theoretical predictions that 1 should experience enhanced acidity as well. In this work, we demonstrate that 1 undergoes a competing excited state intramolecular proton transfer from the OH to carbon atoms at the 3, 6, and 8 positions of the pyrene ring to give quinone methide intermediates. When the reaction is carried out in D2O, reversion of these quinone methides to starting material results in replacement of the ring hydrogens with deuterium, providing a convenient handle to follow the reaction with NMR spectroscopy and mass spectrometry. The quantum yield for the reaction is 0.025 and appears to not be strongly dependent on the water content when aqueous acetonitrile solutions are used. 1-(2-Hydroxyphenyl) pyrene (19) was prepared and studied and shows similar reactivity to 1.

A novel bispyrene compound was synthesized to selectively detect RNA through excimer emission "turn-on" in aqueous solution at physiological pH (7.4). The compound was used to successfully image RNA in HeLa cells.

A novel pyrene-based receptor bearing benzothiazole was synthesized as a good turn-on fluorescent sensor for the recognition of Zn2+. The probe showed an excellent selectivity for Zn2+over most other competing ions (eg, Cr3+, Li+, Cd2+, Al3+, Pb2+, Li+, Mg2+, Ag+, Ca2+, Ni2+, Mn2+, Fe3+, Hg2+, Ba2+, K+, Na+, Cu2+, Fe2+) in EtOH-HEPES (65:35, v/v, pH = 7.20), which might be attributed to the photoinduced electron transfer (PET) mechanism. The formation of 1:1 stoichiometric PBZ-Zn2+ complex was determined based on the Job's plot, 1H NMR titration and ESI-MS. The binding constant of the complex was 4.04 × 104 M?1 with a detection limit of 2.58 × 10?7 M. The potential application of the PBZ in real water samples for recognizing Zn2+ was investigated. Bio-imaging study also revealed that PBZ could be applied to detecting Zn2+ in live cells. These results indicated that PBZ could be a favorable probe for Zn2+.

Effects of substituents on absorption and fluorescence properties of trimethylsilylethynyl- and tert-butylethynyl-pyrenes

Effects of substituents introduced at 1-position of trimethylsilylethynyl- and tert-butylethynyl-pyrenes on absorption and fluorescence properties were investigated. Fluorescence intensities of 1.0 × 10–5 M CH2Cl2 solutions of these pyrene derivatives were significantly larger than that of pyrene. Absorption of a silyl derivative having a formyl group shifted to longer wavelengths as the solvent polarity increased, whereas that of the carbon analog shifted to shorter wavelengths. On the other hand, in the solvent dependence of fluorescence, both fluorescence of them shifted to longer wavelengths as the polarity of the solvent increased. Fluorescence spectra of pyrene derivatives synthesized in this study at saturated concentrations in CH2Cl2 exhibited excimer emissions in the longer wavelength regions compared to that of unsubstituted pyrene. Fluorescence quantum yields of silicon analogs were higher than that of the corresponding carbon analogs in both solution and solid states. From the results of molecular orbital calculations, it was clarified that the effects of the substituents at the 1-position on the pyrene ring on the absorption and fluorescence properties can be explained by the properties of the molecular orbitals corresponding to the respective electron transitions.
