PURPOSE: Provided are novel luminescent materials and a preparation method thereof. The compounds exhibit the maximum emission value in a wide range of spectrum from indigo blue to reddish orange according to aromatic nuclei and peripheral moieties, which are useful as turnable luminescent materials. CONSTITUTION: The method of preparation comprises reacting 1,4-bis£dibromovinyl|benzene or 2,5-bis£dibromovinyl|thiophene through Sonogashira reaction. In formula 1, A is phenyl or thiophenyl; B is phenyl, thiophenyl, furfuryl, 2-thiophenylcarbaldehye or pyridyl. |
