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.

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 general strategy is reported for developing through-bond energy transfer (TBET) fluorescence probes by combining intramolecular charge transfer (ICT). The strategy uses a coplanar donor-π-bridge-acceptor system (SiOPh-PyOH) without spirolactam. The off-on switch of TBET and ICT is controlled by coplanar structure changes in the sensing process instead of spirolactam ring-opening in traditional TBET probes. DFT calculations showed that the energy and charge transfers from SiOPh to PyOH are prohibited. Since the SiOPh has no fluorescence, the probe SiOPh-PyOH shows fluorescence properties similar to that of pyrene. After sensing ONOO?, the silyl ether is removed and the probe changes into ?OPh-PyO?. Electron-donating ICT from OPh to PyO? induces a large redshift of emission to 594 nm (179 nm shift). TBET from OPh to PyO? ensures the probe exhibits a large pseudo-Stokes shift of 213 nm. Furthermore, the probe was successfully used in endogenous ONOO? detection. This study offers a new strategy for the construction of TBET probes emitting in the red region without spirolactam ring-opening, a new ONOO? sensing system using silyl ether as a reaction site, and a method for the deprotection of silyl ethers with ONOOH under mild conditions.
