Abstract

Polydiacetylene-attached titania nanoparticles were synthesized by the reaction with 10,12-pentacosadiynoic acid (PDA). The surface of titania nanoparticles was modified with a silane coupling agent, 3-aminopropyltrimethoxy silane (APTMS). 10,12-Pentacosadiynoic acid (PDA) was also modified by the esterification of N-hydroxy-succinimide (HS) with 4-pyrrolidinopyridine as a catalyst. The modified PDA (HS-PDA) was attached to titania by the reaction between modified TiO2nanoparticles and HS-PDA. Products were purified and then further polymerized by the photochemical 1,4-addition reaction. These PDA-attached TiO2 nanoparticles were characterized with NMR, IR and thermogravimetry (TG).
