title: A novel thermally reversible soluble-insoluble conjugated polymer with semi-fluorinated alkyl chains: enhanced transistor performance by fluorophobic self-organization and orthogonal hydrophobic patterning.
abstract: SFA-PQT exhibits self-assembly via a fluorophobic effect in a non-fluorous solvent, which leads to an enhanced electrical performance. Ambipolar transistors and inverters with p- and n- type bilayers are enabled by the unique thermally reversible soluble-insoluble properties of SFA-PQT. More importantly, the hydrophobicity of SFA-PQT facilitates orthogonal hydrophobic patterning and a patterned inverter exhibits low voltage dissipation, a narrow transition zone, a high gain value, and negligible hysteresis.
