Phosphorus Containing Dendrimers: Surface Chemistry and Applications

摘要

The synthesis of phosphorus containing dendrimers is described up to the fifthgeneration (96 terminal groups). The surface chemistry of these dendrimers allows the grafting of various functionalities such as phosphate (6 O-P(O)(OEt)2 groups), aminophosphate (up to 96 N-P(O)(OEt)2 groups), aminophosphite (up to 96 N-P(OEt)2 groups), functionalized phosphonate (up to 96 HC(OH)P(O)(OR)2 (R = Et, (CH2)11CH3), up to 96 HC(N-Pr)P(O)(OEt)2, or up to 48 CH=CH-P(O)(OEt)2), phosphorus ylide (6 C(O)CH=P(Ph)3), carboxylic acid (up to 24 CH=CH-C(O)OH), and tetraazamacrocycle (up to 12 cyclam). These surface functionalities have been chosen due to the well known properties of the corresponding monomers and/or polymers in various areas such as adhesives, flame retardants, fuel additives, sequestring agents.
