We investigate the energy transfer of a highly ordered π-conjugated liquid crystalline mol. containing two chromophores of biphenyl and pyrene moiety, in which the mol. was prepared by esterification of fluorinated biphenyl compound and 1-pyrenebutanol. DSC, POM and XRD results show that this mol. forms a highly ordered smectic liquid crystalline mesophase, in which the π-conjugated mol. was strongly packed together over large-areas. We show that the liquid crystalline bi-chromophoric systems with highly ordered structure exhibit the energy hopping and transfer to the chromophore with the energetically lowest S1 state. From the single-mol. spectroscopy of the biphenyl and pyrene chromophore in solution, we show an intramol. energy transfer from biphenyl to pyrene moieties. In solid thin film, highly ordered structure of the liquid crystal plays a significant role in the formation of the excimer and perfect energy transfer between the chromophores.
