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

Abstract

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 typical semiconducting polymers, and charge mobilities of their thin films are boosted remarkably. Finally, this new method can be utilized to easily fabricate the array of field-effect transistors with high charge mobilities in an economic way.

Figure 1. Figure 1.: Schematic illustration of the thin films fabrication based on conjugated polymers by using the AOW method. Polymer solution is dropped on water surface to form a partly spread solution drop. As solvent evaporating at contact line, polymers gradually assemble at the edge and result in the formation ofmore » thin films with stripe-like structures. Thin films can be transferred onto solid substrates and dried by blowing with dry N2, and the resulting thin films are used to fabricate field-effect transistors.« less
