“…) and spin‐casting (Supporting Information Fig. S2) are similar to that observed previously for poly(3‐alkylthiophene):polystyrene mixtures spin‐casted from various solvents on homogenous and inhomogenous substrates . Strong incompatibility of polythiophenes and polystyrene leads to phase demixing during solvent evaporation.…”

“…This bottom‐up concept, demonstrated for the first time by Böltau et al for model (dielectric) polymers spin‐casted on pre‐patterned substrates, showed that domain growth in a phase separating polymer blend can be guided by a substrate chemical pattern. Recently, the application of this method has been demonstrated on several blends of conjugated polymers, as well as blends of insulating and semiconducting polymers spin‐casted on patterned substrates. It was shown that templates prepared by various techniques such as lithography, micro‐contact printing of self‐assembling molecules, dip‐pen lithography can be successfully used to guide the phase ordering in composites of organic semiconductors.…”

Pattern replication in solution‐deposited thin films of insulating and conjugated polymer mixtures might provide an alternative to spatially resolved printing techniques for the fabrication of polymer‐based circuitries. Though it has been previously shown that phase separation in the course of spin‐casting leads to the formation of domain structures resembling the chemical patterns pre‐set on the film substrate, finding optimal casting conditions is a tedious process, which requires multiple sample preparations. Here, we have demonstrated pattern replication in a mixture of poly(3,3′′′‐didodecyl quarter thiophene) (PQT‐12) and deuterated poly(styrene‐co−4‐bromostyrene) (dPBrS) deposited by horizontal‐dipping on substrates, patterned with self‐assembling molecules by micro‐contact printing. Moreover, we show that casting conditions for accomplishing pattern replication can be efficiently screened by preparing thickness gradient samples. We have optimized the reconstruction of the substrate pattern in the PQT‐12:dPBrS film. Our results prove that desired structures of semiconducting and insulating polymers can be produced in a simple, high‐throughput technological process. © 2013 Wiley Periodicals, Inc. J. Polym.

Protein interactions with surfaces of promising conducting polymers are critical for development of bioapplications. Surfaces of spin-cast and postbaked poly(3-alkylthiophenes), regiorandom P3BT, and regioregular RP3HT are examined prior to and after adsorption of model protein, bovine serum albumin, with time-of-flight secondary ion mass spectrometry, atomic force microscopy, and X-ray photoelectron spectroscopy. The multivariate method of principal component analysis applied to ToF-SIMS data maximizes information on subtle differences in surface chemistry: PCA reveals alkyl side chains and conjugated backbones, exposed for RP3HT and P3BT, respectively. Phase imaging AFM shows semicrystalline microstructure of RP3HT and amorphous morphology of P3BT films. A cellular-like pattern of proteins adsorbed on RP3HT develops with coverage to more uniform overlayer, observed always on P3BT. The amount of adsorbed protein, determined by XPS as a function of BSA concentration (up to 10 mg/mL), is ∼21% lower for RP3HT than P3BT (up to 1.1 mg/m(2)). Although PCA differentiates protein from polythiophene, relative protein surface composition evaluated from ToF-SIMS saturates rather than increases with amount of adsorbed BSA from XPS. This reflects ToF-SIMS sensitivity to outermost layer of proteins, enabling multivariate analysis of protein conformation or orientation. PCA distinguishes between amino acids characteristic for external regions of BSA adsorbed to P3BT and RP3HT. These amino acids are identified for P3BT and RP3HT as hydrophilic and hydrophobic, respectively, by relative hydrophobicity of amino acid side chains. Alternative identification with BSA domains fails, pointing to substrate-induced changes in conformation and degree of denaturation rather than orientation of adsorbed protein.

“…Deposited SAMs are available with a variety of molecular architectures, or their mixtures allow for a controlled modification of surface tension and for a tunable variation of wettability . SAM micro‐patterns prepared over broad substrate areas can align the domains of spin cast blends of conjugated polymers, one of the key factors in the design of high‐efficiency organic solar cells …”

The origin and formation of the dipole moment at the interface of metal electrode and thin organic film is crucial for the fabrication of high‐performance organic electronic devices. In this work, model polymer multilayer systems are studied in which interfaces are modified heterogeneously with thiol‐based self‐assembled monolayers (SAM). Due to the presence of polar terminal group (‐COOH) in SAM and polar pendant groups (‐COOH, ‐C(O)OCH3) within studied polymers, it is pointed out that the resultant interface energetics differ from the expected ones as one would expect from the chemical character of the self‐assembled molecules used to tune junction properties. This is discussed in terms of inter‐association and depolarization effects between polymer and thiol modified substrate. The presented model systems may serve as an interaction reference for SAMs and semiconducting polymers containing similar moieties, utilized for the fabrication of organic electronic devices.
