By comparing the influence of the solvent polarity, in the fluorescence experiment, for PTCP and PPCP, the bathochromic shifts are attributed to the locally excited process.

通过考察溶剂极性对该类D-π-A分子光物理性能(来源：A28BC论a5文网www.abclunwen.com)的影响，发现当共轭体系较小时，PTCP和PPCP发射的是本体荧光，即源于局部激发态LE态。

Whereas the absorption spectrum undergoes minor change with increasing polarity of the solvents, the fluorescence spectrum experiences a distinct bathochromic shift in the band position and the fluorescence quantum yield increases reaching a maximum before decrease with increasing the solvent polarity.

By the testing means of electron-spectroscopy for chemical analysis , thermogravimetric analysis , differential scanning calorimetry , transmission electronmicroscopy , the results have shown that the emulsion polymerization in situ in the presence of nano-particle of calcium carbonate can happen smoothly and successfully and the surface of nano-particle of calcium carbonate have been capsulated by polymer of acrylates, which prevent from the agglomerating of nano-particles of calcium carbonate. Because the copolymer of acrylate has good compatibility with some plastics such as PVC, ABS, AS and so on, so the dispersion of nano-scale calcium carbonate as nanometer size in these plastics can be reached more easily and the effects of nanometer can happen.
