Synthesis and Optoelectronic Characterization of Some Star-Shaped Oligomers with Benzene and Triphenylamine Cores

Figure 3

Absorption (a) and fluorescence (b) spectra of conjugated oligomers with benzene core: D4, D5, D6, in dilute chloroform solution (10⁻⁵M). Emission spectra were obtained upon excitation at the absorption maximum.
