Nanoparticles, nanodots (d <~30nm), and nanowires of conjugated polymers have been recently highlighted as promising nanomaterials for aqueous-based applications such as biomedical imaging and therapy, and photocatalytic solar energy conversion. It is because of their higher energy absorption and emission properties, and photostability than single molecular dyes. However, active radicals based on oxygen such as superoxide radical anions or hydroxyl radicals are commonly generated in such applications and seriously deteriorate their optoelectronic properties by destroying the electron delocalization of conjugated backbones. In this contribution, it is presented that the assembly of conjugated polymer nanomaterials with phospholipids via a film-shattering method ensures a dense molecular packing between the alkyl tails of the phospholipids and the alkyl side chains of the conjugated polymers, thereby protecting the conjugated backbones from the harsh attacks by the active radicals in the aqueous media. |
