The facile control of chiral packing in poly(p-phenylenevinylene) (PPV) spin-cast films was investigated. The circular dichroism (CD) spectroscopy was used to demonstrate that spin-cast films from chiral π-conjugated polymer can be easily and selectively fabricated from different solvents to have correspondingly different architectures with opposite handedness. By varying the spin-casting solvent or annealing conditions, three distinct film architectures can be prepared from the PPV. The architectures included two chiral organizations with opposite handedness and a disordered assembly that does not exhibit and chiral packing.
