  • Detection and functionalization of dendrimers
    Patent number: 7368512
    Abstract: A method of detecting unreacted termini within a dendritic structure is achieved by exposing a dendrimer to a single generating compound capable of bonding to and tagging a deprotected but uncoupled termini. A signal generated by the signal generating compound to an otherwise uncoupled termini provides detection of the unreacted termini.
    Type: Grant
    Filed: September 14, 2004
    Date of Patent: May 6, 2008
    Assignee: University of South Florida
    Inventors: George Newkome, Charles N. Moorefield, Claus Weis

  • Method of utilizing isocyanate linkages for forming multi-tier cascade polymers
    Patent number: 5773551
    Abstract: A method of synthesizing multi-tier cascade polymers and the polymers made thereby are formed by reacting at least one tier of a polymer with a functionalized isocyanate having the following formula:O.dbd.C.dbd.N--C(CH.sub.2 --R).sub.3with R being selected from the group including:a) --(CH.sub.2).sub.n --CH.sub.2 --COOR'with R' being selected from the group consisting of alkyl, cycloalkyl, aryl, heteroaryl-polycycloalkyl, adamantyl, n.dbd.0-10;b) --O--(CH.sub.2).sub.n --CH.sub.2 COOR'c) --O--(CH.sub.2).sub.n --CH.sub.2 --CNwith R' being selected from the group consisting of alkyl (C-1 to C-20), cycloalkyl (C-3 to C-10), aryl, heteroaryl, polycycloalkyl, adamantyl, n=0-10; andd) --CH.sub.2 --(CH.sub.2).sub.n --O--R"with n=0-10, R" being selected from the group consisting of alkyl, cycloalkyl, aryl, heteroaryl ester functionality, and a sulphur or a silicon atom bearing substituents selected from the group including: ##STR1## --SO.sub.2 --R'", --SiR'".sub.3 --(CH.sub.2 ).sub.n --CH.sub.2 --CN, --(CH.sub.2 ).
