And it does not emit fluorescence. The (DBS-BRDB),, nanoparticle can be decomposed into DBS-BRDB association molecule by alcohol. So that,the resonance scattering peaks and the red-violet disappear in presence of enough alcohol.

• 当纳米微粒体系加入乙醇后,体系的红紫色和共振散射峰消失,吸收峰和荧光峰恢复,由于乙醇致使{DBS-BRDB}_n纳米微粒分解为DBS-BRDB分子。
