In order to prepare new functional macromolecule material, the coupling reaction of acenaphthene catalyzed by [Bmim]Cl/FeCl3 ionic liquid was investigated under mild reaction conditions and without any additional organic solvent.
Conclusions In conclusion, Pure 3,3'-biacenaphthenys were obtained, which can be used in the synthesis of aromatic polymers, thus the approach of the preparing of new function macromolecule material is offered.

When the solid material distribution in Figure 2(a) is imported to PATRAN, the 1st order frequency computed by NASTRAN is 61.61 (Hz), whis is slightly larger than that (60.76 Hz) with void and soft materials for Figure 2(a).
That is, soft materials have little influence on frequency of this structure.
Therefore, soft materials can significantly increase fundamental frequency of plate vibrations.
Void and soft materials have little effect on frequency of in-plane vibration but affect out-of-plane vibrations of plate structures considerably.

Materials MEH-PPV was purchased from Sigma Aldrich.
The materials were used as the active layers without any further purification.
However, the two materials are mixed together and are effectively connected in series.
