We developed a new method combining the in situ liquid-solid phase reaction and self-assembly in solution to synthesize novel inorganic/organic small molecular semiconductor core-shell nanoparticles of ZnS/PTCDA (ZPNPs). This method is a one-step process which can produce stoichiometric inorganic/organic core-shell nanoparticles and does not introduce any impurity. The film of ZPNPs exhibited an ultrasensitive detection of aniline vapor. The film of ZPNPs can highly selectively distinguish aniline vapor from many volatile organic compounds and water due to the strong synergistic interactions of π-π and hydrogen-bonds between electron donor (aniline) and acceptor (PTCDA) molecules, in which the detection limit was lowered to 100 ppb at room temperature.

The synthesis and self-assembly of twelve semifluorinated first-generation dendrons or minidendrons attached to electron-acceptor (n-type) groups generated from various combinations of eight acceptors and three dendrons arc reported. Dendrons attached to small electron-acceptor molecules mediate their self-assembly into π-stacks located in the center of a supramolecular helical pyramidal column with the long axis of the acceptor perpendicular to the long axis of the column. Dendrons attached to large electron-acceptor molecules, such as perylene bisimide, mediate the assembly of their acceptors in an unprecedented arrangement of π-stacks that have the long axis of the acceptors parallel to the long axis of the supramolecular pyramidal column. All supra_molecular columns self-organize into various periodic columnar arrays that exhibit liquid-crystalline phases, crystalline phases, or a liquid-crystalline phase with enhanced intracolumnar order. The present study demonstrates the simplicity and the versatility of the concept of assembly of π-type electroactive groups mediated by semifluorinated dendrons and assesses the scope and limitations of this supramolecular strategy.
Single-molecule spectroscopy of interfacial electron transfer

It is widely appreciated that single-molecule spectroscopy (SMS) can be used to measure properties of individual molecules which would normally be obscured in an ensemble-averaged measurement. In this report we show how SMS can be used to measure photoinduced interfacial electron transfer (IET) and back electron transfer rates in a prototypical chromophore-bridge-electrode nonadiabatic electron transfer system. N-(1-hexylheptyl)-N′ -(12-carboxylicdodecyl)perylene-3,4,9,10-tetracarboxylbisimide was synthesized and incorporated into mixed self-assembled monolayers (SAMs) on an ITO (tin-doped indium oxide, a p-type semiconductor) electrode. Single-molecule fluorescence time trajectories from this system reveals "blinks", momentary losses in fluorescence (>20 ms to seconds in duration), which are attributed to discrete electron transfer events: electron injection from the perylene chromophore into the conduction band of the ITO leads to the loss of fluorescence, and charge recombination (back electron transfer) leads to the return of fluorescence. Such blinks are not observed when an electrode is not present. The fluorescence trajectories were analyzed to obtain the forward and back electron rates; the measured rates are found to lie in the millisecond to second regime. Different rates are observed for different molecules, but the lifetime distributions for the forward or back electron transfer for any given molecule are well fit by single exponential kinetics. The methodology used is applicable to a wide variety of systems and can be used to study the effects of distance, orientation, linker, environment, etc. on electron transfer rates. The results and methodology have implications for molecular electronics, where understanding and controlling the range of possible behaviors inherent to molecular systems will likely be as important as understanding the individual behavior of any given molecule.
