2. Topotactic Polymerization of Diacetylene-Containing SAMs as a Method for Surface-Derivatization of Nanoparticles Timothy Hanks and Laura Wright, Deparment of Chemistry, Furman University
The focus of this work is to construct multifunctional nanoscale objects. A key concept is the self-assembly of long-chain alkanes containing a conjugated butadiyene (diacetylene, DA) moiety in the chain. If these can be organized properly, they will undergo a topotactic polymerization initiated by UV irradiation. In the case of highly solvated nanoparticles, we believe the DAs on a single particle undergo polymerization. In weaker solvents, we believe the particles are aggregating, with the DA-containing chains interpenetrating. Upon photolysis, the particles cross-polymerize to form insoluble materials
When we treat THF solutions of nanoparticles with a long-chain alkane containing a DA and terminated by a functionality of interest – usually a carboxylic acid or an ionic fluorophore, the hydrophobic alkane chains interpenetrate, leaving a hydrophilic surface.
