• they correlate the monomer transition energy (ω0), the magnitude of the electronic coupling between the thiophene monomers in the macromolecules (J), and the extent of the delocalized π-conjugated system [17]. Experimental The solutions were freshly prepared with chloroform (Merck, UVASOL). UV–vis

• macromolecules containing two different types (A and B) of incompatible side chains (so-called binary combs). Side chains of the binary combs are strongly adsorbed on a surface and segregated with respect to the backbone. The thickness of surface domains formed by the B side chains is controlled by the

• interaction with the substrate. We predict the stability of direct and inverse disc-, torus- and stripelike nanostructures. Phase diagrams of the film are constructed. Keywords: comb copolymers; macromolecules; adsorption; self-organization; Introduction Recent advances in macromolecular synthesis allow

• precise control over structure and polydispersity of architecturally complex polymers [1][2][3]. Among these polymers are comb or brush copolymers, i.e., macromolecules which consist of a backbone and attached side chains [4][5]. Originally the interest in comb copolymers was motivated by the desire to
