Title: Polypeptide Composite Particle-Assisted Organization of π-Conjugated Polymers into Highly Crystalline “Coffee Stains”

Abstract

We demonstrate that homopolypeptides covalently tethered to anisotropically shaped silica particles induce crystalline ordering of representative semiconducting polymers. Films drop-cast from chloroform dispersions of poly(γ-stearyl-l-glutamate) (PSLG) composite particles and poly(3-hexythiophene) (P3HT) led to highly ordered crystalline structures of P3HT. Hydrophobic–hydrophobic interactions between the alkyl side chains of P3HT and PSLG were the main driving force for P3HT chain ordering into the crystalline assemblies. It was found that the orientation of rigid P3HT fibrils on the substrate adopted the directionality of the evaporating front. Regardless of the PSLG-coated particle dimensions used, the drop-cast films displayed patterns that were shaped by the coffee ring and Marangoni effects. PSLG-coated particles of high axial ratio (4.2) were more efficient in enhancing the electronic performance of P3HT than low axial ratio (2.6) homologues. Devices fabricated from the ordered assemblies displayed improved charge-carrier transport performance when compared to devices fabricated from P3HT alone. Furthermore, these results suggest that PSLG can favorably mediate the organization of semiconducting polymers.

A Facile Approach to Improve Interchain Packing Order and Charge Mobilities by Self-Assembly of Conjugated Polymers on Water

Journal Article Yang, Yizhou ; Liu, Zitong ; Chen, Jianmei ; ... - Advanced Science

Development of facile and economic approaches for assembling organic semiconductors into more ordered structures toward high charge mobilities is highly demanding for the fabrication of organic circuits. Here a simple and facile approach is reported to prepare conjugated polymer thin films with improved crystallinities and charge mobilities by self-assembling semiconducting polymers on water. The formation of polymer thin films with more ordered structures is attributed to coffee ring effect induced by solvent-evaporation on water, and the hydrophobic nature of conjugated polymers that forces the polymer chains to pack densely and orderly on water surface. This approach is applicable to typicalmore »« less

Measuring the Degree of Crystallinity in Semicrystalline Regioregular Poly(3-hexylthiophene)

Journal Article Shen, Xiaobo ; Hu, Weiguo ; Russell, Thomas P. - Macromolecules

By using a combination of wide-angle X-ray diffraction (WAXD), mass density, and ¹³C solid-state nuclear magnetic resonance (NMR) measurements, a quantification of the absolute degree of crystallinity in regioregular poly(3-hexylthiophene) (rr-P3HT) is presented. A regiorandom P3HT (rra-P3HT), lacking long-range order, was used to separate the crystalline contribution from the total scattering in WAXD, thus yielding degrees of crystallinity in the range of 47–56% at room temperature for three different rr-P3HTs. For the same rr-P3HT with identical processing history, NMR yields degrees of crystallinity that are consistently ~10% greater than that obtained by WAXD, which can only be explained by orderedmore »« less

Structural Transitions of Nanocrystalline Domains in Regioregular Poly(3-hexyl thiophene) Thin Films

Journal Article Yang, H ; Shin, T ; Bao, Z ; ... - Journal of Polymer Science Part B: Polymer Physics

The effects of solution processing and thermal annealing on thin film morphology and crystalline structures of regioregular poly(3-hexyl thiophene) (RR P3HT) are studied in terms of molecular weight (M{sub w}). Using grazing-incidence X-ray diffraction, {pi}-conjugated planes in drop-cast films from chloroform solutions are found to be preferentially oriented parallel to the substrates regardless of M{sub w}. However, the mesoscale nanocrystalline morphology of the drop-cast films is significantly affected by M{sub w}, exhibiting a distinctive morphological transition from short nanorods to long nanofibrils above a critical number-averaged M{sub w} ({approx} 3.6 kDa). This is probably due to the change in amore »« less

Magnetic-field annealing of inverted polymer:fullerene hybrid solar cells with FePt nanowires as additive

Journal Article Chen, Chiang-Ting ; Chen, Yang-Fang ; Hsu, Fang-Chi ; ... - Applied Physics Letters

We demonstrate a facile annealing method to improve the polymer chain ordering of poly(3-hexythiophene) (P3HT):fullerene blend triggered by a small amount of FePt nanowires (FePt NWs). By applying a magnetic field perpendicular to the substrate during the solvent drying process, the resulting P3HT:fullerene:FePt NWs film becomes highly optical anisotropy and exhibits a much stronger X-ray diffraction intensity of P3HT. We hypothesize that the coupling force between the FePt NWs and P3HT can assist the polymer chain alignment leading to an improved device performance. The proposed approach is simple and can be applied to other polymer blend systems as well.

Plastic neutron detectors.

Technical Report Wilson, Tiffany M S ; King, Michael J ; Doty, F Patrick

This work demonstrated the feasibility and limitations of semiconducting {pi}-conjugated organic polymers for fast neutron detection via n-p elastic scattering. Charge collection in conjugated polymers in the family of substituted poly(p-phenylene vinylene)s (PPV) was evaluated using band-edge laser and proton beam ionization. These semiconducting materials can have high H/C ratio, wide bandgap, high resistivity and high dielectric strength, allowing high field operation with low leakage current and capacitance noise. The materials can also be solution cast, allowing possible low-cost radiation detector fabrication and scale-up. However, improvements in charge collection efficiency are necessary in order to achieve single particle detection withmore »« less
