  • Title: Synthesis and photophysical properties of nonbenzoid ended fluorophores.
    Author: Shao H, Chen X, Wang Z, Lu P.
    Journal: J Phys Chem B; 2007 Sep 06; 111(35):10386-96. PubMed ID: 17696391.
    Abstract:
    A series of pi-conjugated compounds (1-23) were successfully synthesized by the Sonogashira, Suzuki, and Wittig-Horner reactions. The structure-property relationship about photoluminescence based on these synthesized compounds was systematically discussed in detail. In addition, energy gaps between ground and excited states of these compounds, which were in good agreement with the experimental observation, were calculated by the semiempirical parametrized PM3 method. It was revealed that emission efficiency largely depends on molecular structure, aggregation type, and size of nanoaggregates.
