So it form (DBS-BRDB), composite nanoparticle in red-violet that exhibit two resonance scattering peaks at 360 nm and 420 nm,a characterization resonance scattering peaks at 520 nm. And the resonance scattering effect appears.

• DBS-BRDB分子间存在较强的分子间作用力和疏水作用力而生成{DBS-BRDB}_n纳米微粒,在360,470nm处产生2个共振散射峰,在520nm产生1个特征共振散射峰。
