POLY 472 |
| We report here the synthesis and characterization of a novel series of amphiphiles consisting of a well-defined oligothiophene trimer asymm-etrically end-substituted with a hydrophobic alkyl chain and a hydrophilic poly(ethylene glycol). The Ą,Ą'-disubstituted oligothi-ophenes were synthe-sized by Suzuki coupling and Stille coupling reaction. 1H NMR, GC-MS, AFM and DSC were used to confirm the molecular structures of these molecules. The self-assembling behavior of the hydrophobic and hydrophilic blocks varied depending on the type of solvent. Various surface morphologies were also found from their thin films prepared on mica by either spin-coating or dip-coating method. |
