title: [Study on the spectral properties of a new fluorene derivative].
abstract: A new big pi-conjugated, symmetrical fluorene derivative, 9, 9-bis(2-ethylhexyl)-2,7-bis(2-(4-methoxy) benzene-2, 1-ethenyl) fluorene (abbreviated as MO-Flu-MO) was synthesized and characterized by elemental analysis, mass spectral, UV-Vis and IR spectral. Spectral characteristics of this compound, including linear absorption spectral and one-photon fluorescence spectral, were measured in acetonitrile, methylene chloride, tetrahydrofuran and hexane at room temperature. It was found that solvent effects have different influence on absorption spectral and fluorescence spectral, major reasons of such spectral behavior are discussed.
