摘要
The title compound 4-（N,N-diphenylamino）styrene-4＇-N-methylpyridinium iodine （abbreviated to PASMPI） was synthesized by a facile condensation reaction with a high yield. The red crystal including a molecule of CHCI3 was obtained by recrystallization in chloroform/ethanol. Its crystal structure was determined by a four-circle diffractometer. The crystal data： C26H23N2ICHCI3, Mr = 609.73, orthorhombic, space group Pbca, a = 15.422（5）, b = 14.042（5）, c = 24.693（5） A, V= 5347（3） A^3, Z = 8, Dc = 1.515 g/cm^3, F（000） = 2432,μ（MoKa） = 0.057 mm^-1, the final R = 0.0439 and wR = 0.0772. The results reveal that the molecule is a completely reverse system. The molecular rotation from non-coplanar to coplanar may play an important role in increasing the fluorescence intensity under the condition of staining DNA.
