Abstract:

9,10-Bis((4-(2-(2-(2-methoxyethoxy)ethoxy)ethoxy)phenyl)ethynyl)anthracene(1) was synthesized by Sonogashira coupling. Its structure was characterized by 1H NMR and MALDI-TOF mass spectroscopy. The self-assembling behavior of compound 1 was investigated by means of differential scanning calorimetry(DSC), thermal polarized optical microscopy(POM), and small-angle X-ray scattering(SAXS) at the bulk state. Compound 1 self-assembled into smectic A phase(SmA) in the solid state. Spectroscopic analysis suggested that compound 1 inherited the characteristic of high fluorescence quantum yield(Φf) of disubstituted anthracenes. The title compound 1 is a kind of photoluminescence materials with good performance.

 

Key words: self-assembly, anthracene, fluorescence quantum yield, smectic A phase, Sonogashira coupling reaction
