    The preparation of ribose-free ‘artificial dinucleotides’: A new approach to molecular recognition? (1989)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 7 (1989), S. 19-26 
    Details
    ISSN: 1573-1111
    Keywords: Artificial dinucleotide ; molecular recognition ; cytosine-guanine dimer
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The synthesis of the cytosine-guanine linked dimer1, and its symmetric guanine-guanine analogue2 are described. Compound1 is the first homogeneous ribose-free system to be prepared and characterized in which molecular recognition by complementary guanine-cytosine base-pairing might be possible. It is thus prototypical of a new and potentially large class of ‘artificial oligonucleotides’.

    Exciton interactions in synthetic porphyrin dimers (1989)
    Springer
    Photosynthesis research 22 (1989), S. 201-210 
    Details
    ISSN: 1573-5079
    Keywords: exciton theory ; optical spectroscopy ; porphyrin dimer ; Soret band
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The Soret absorption spectra of six synthetic rigid porphyrin dimers whose crystal structures have been determined are simulated using simple exciton theory. The objective is to test the validity of the point dipole and associated approximations; the electronic interaction parameters are thus calculated using data obtained from the monomer spectra, with no adjustable parameters. Satisfactory agreement between theory and experiment is obtained for one class of dimers but not for a second. This poses a challenge for semiempirical electronic structure methods as to whether improvements over the point dipole calculations can be obtained.
