Solvent Additive to Achieve Highly Ordered Nanostructural Semicrystalline DPP Copolymers: Toward a High Charge Carrier Mobility. (2nd October 2013) - An, Tae Kyu
Abstract A facile spin‐coating method in which a small percentage of the solvent additive, 1‐chloronaphthalene (CN), is found to increase the drying time during film deposition, is reported. The field‐effect mobility of a PDPPDBTE film cast from a chloroform–CN mixed solution is 0.46 cm2 V‐1 s‐1. The addition of CN to the chloroform solution facilitates the formation of highly crystalline polymer structures.
