英文摘要	A novel beta' phase crystal with lamellar structure of monodisperse poly(9,9-dioctylfluorene) (pfo) has been prepared by means of melt crystallization, demonstrating similar optical properties with beta phase crystals. a preliminary determination of unit cell dimensions and molecular packing (orthorhombic, a = 1.30 nm, b = 2.22 nm, c = 3.36 nm, 4 chains, with space group pmc2(1) and density 1.06 g/cm(3)) was made by combined analysis of the selected-area electron diffraction (saed) and x-ray diffraction (xrd) patterns. in the lamellar crystals, the molecular backbone chains are parallel to the lamellar plane with the alkyl side chains interdigitation in the thickness of lamella.
