    Notes: Macrobicyclic Endoreceptors: Synthesis, Crystal Structure, and Inclusion of Organic GuestsThe macrobicyclic ligand 2 is synthesized in a one-step cyclization procedure. According to an X-ray structure analysis three dichloromethane guest molecules are included inside the cavity, whereas water and methanol are found outside the cavity. The rigid endo preorganization of the nitrogen donors allows the complexation of three 2,9-disubstituted 1,10-phenanthrolines inside the cavity.

    Repetitive-Synthesis of Bulky Dendrimers - A Reversibly Photoactive Dendrimer with Six Azobenzene Side Chains (1993)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 126 (1993), S. 1161-1169

    ISSN: 0009-2940

    Topics: Chemistry and Pharmacology
    Notes: Dendrimers with bulky repeating units containing up to 43 benzene rings (in 9) have been obtained by using a repetitive divergent synthetic strategy (three generations). The new functional dendrimer 13 containing six azobenzene units at the periphery was synthesized allowing a reversible switching of the shape and size of the molecule upon irradiation. An X-ray structure analysis of the dendritic molecule 3a shows the inclusion of acetonitrile.
