Construction of Segregated Arrays of Multiple Donor and Acceptor Units Using a Dendritic Scaffold: Remarkable Dendrimer Effects on Photoinduced Charge Separation
visualization of a petal-like structure of DP12 superset Py2F3. Photoexcitation of the zinc porphyrin units in DPm superset Py2Fn results in a zinc porphyrin-to-fullerene electron transfer to generate a chargeseparation. The charge-separation rate constant (kCS) in CH2Cl2 at 20 degrees C increases from 0.26 x 10(10) to 2.3 x 10(10) s(-1) upon increment of m and n, whereas the charge-recombination rate constant

The present invention relates to a method for preparing haptens of formulae I and II that are useful in the preparation of immunogens, antibodies and conjugates, for use in competitive immunoassays for the detection of ractopamine, isoxsuprine and ritodrine. The haptens are prepared by reacting a phenylethanolamine derivative of formula D with a phenylalkylcarbonyl derivative of formula E:

template that serves as structural scaffold to self‐assemble an ordered and mixed array of ethynyl‐pyrene‐ and ethynyl‐Nile‐red‐nucleoside conjugates. Fluorescence spectroscopy revealed evidence for energy transfer between the two different chromophores. Moreover, fluorescence quenching is significantly enhanced by the attached fullerene in mixed assemblies of different chromophore ratios. This indicates
