The size and morphology control of polydiacetylene microcrystals has been investigated by changing preparation conditions such as temperature and added surfactant in the reprecipitation method. As a result, fibrous microcrystals (diameter: 50 nm, length: 5-10 μm) of conjugated polymers were interestingly fabricated under an optimum condition. The formation mechanism of polydiacetylene fibrous microcrystals and their optical properties were also investigated.
