“…Consequently, the conducting polymers MEH-PPV and P3HT behave like standard homopolymers such as polystyrene in terms of the spin-coating preparation technique. [40] For both polymers the film thickness can easily be controlled by changing the concentration of the initial polymer solution with good reproducibility.…”

The morphology inside photoactive blended films of two conjugated homopolymers poly [(1-methoxy)-4-(2-ethylhexyloxy)-p-phenylene-vinylene] (MEH-PPV) and poly(3-hexylthiophene-2,5-diyl) (P3HT) is investigated. For both homopolymers a linear dependence of the installed film thickness from the concentration of the polymer solution used in spin coating is probed. This dependence allows preparation of an efficient series of blended films with constant thickness and different blending ratios. Information about the lateral structure inside the films is gained from grazing incidence small angle X-ray scattering. At the calculated critical blending ratio the smallest lateral separation between adjacent domains is found representing the highest surface contact between both homopolymers in the films. The presence of wetting layers at both interfaces as detected with X-ray reflectivity and atomic force microscopy is promising for photovoltaic applications. UV/Vis spectroscopy complements the structural investigation.

“…The substrate was therefore prepared by spin-coating a dilute polystyrene solution on a silicon wafer. [24] Tapping mode AFM measurements gave average roughness R a values as low as 0.1-0.2 nm (Figure 1a), quite comparable to the features of freshly prepared mica-peeled Au surfaces (a substrate typically used in DPN experiments). [22] The coating thickness was measured by both AFM and laser profilometry (see Experimental), and resulted to be about 200 nm (Figure 1b).…”

Model high density DNA arrays have been realized by direct deposition with Dip-Pen Nanolithography of acrylamido-functionalized oligonucleotides (23-mer) on spin-coated, flat polystyrene surfaces. A highly specific interaction between the acrylamide end functionality and polystyrene was found. The surface morphology of the model array was studied by atomic force microscopy (AFM). Spots are clearly seen both in topography and demodulation modes. The array withstands the hybridization process with label free, complementary oligonucleotides and the following cleaning procedures. The final AFM characterization showed significant changes especially in demodulation images which may be an indication that molecular recognition between complementary oligos has occurred.

Chemical Synthesis, Electronic Study, and Vibrational Analysis of a New Organic Copolymer Based on PVK and 3-nhexylthiophene

et al. 2010

Conjugated polymers containing carbazole moieties either in the main or in the side chains have attracted much attention because of their unique electronic properties, to their high photoluminescence quantum efficiency, and thermal stability. The aim of this work is to study a new organic copolymer which combines the PVK properties and those of PHT. We will describe in this study the protocol synthesis, the chemical structure, and the electronic and vibrational properties of the resulting copolymer. The experimental and theoretical studies are combined in order to describe the properties of this material. These properties suggest this compound (PVK-PHT) to be a good candidate for optoelectronic application.
