We have synthesized a highly regioregular poly(3-alkylthiophene) containing an oxygen atom in the side chain, poly(3-pentylmethoxythiophene) (P5OMe). We have studied the formation of Langmuir-Blodgett (LB) multilayer structures prepared by mixing P5OMe with highly isotactic polymethylmethacrylate (PMMA), and we have characterized the structure...

Tapping mode atomic force microscopy (AFM) was employed to study the surface structure of spin-coated and solvent-cast films of the newly synthesized electroluminescent copolymer TT9 and its fractions A and B. Fraction A is well soluble in chloroform while fraction B forms aggregates of high molecular weight in the same solvent. TT9 and...
