Abstract
The emission wavelength in conjugated copolymers is determined by the various monomers used, their sequence in the polymer backbone, the effective conjugation length of the material, and intra- and intermolecular interactions of the different units. This paper will discuss the influence of conjugation length as well as the influence of intramolecular charge-transfer on the absorption and emission properties. Fluorene, benzothiadiazole and a third comonomer (fluorene, xylene or triphenylamine) were used as building blocks. The influence of monomer sequence is probed as well by comparing sequentially random copolymers to their sequentially defined ones with identical monomer ratios. Model oligomers were also made for comparison.
