Cross-linked polymer dots with intense and narrow yellow emission were designed using boron-dipyrromethene (BODIPY) polymer as the acceptor and poly[9,9-dioctylfluorenyl-2,7-diyl--1,4-benzo-{2,1'-3}-thiadiazole] (PFBT) polymer as the donor. The emission fwhm's of the polymer dots (Pdots) were 37 nm. CL-BODIPY 565 Pdots were about 5 times brighter than commercial quantum dots (Qdots) 565 under identical experimental conditions. Specific cellular targeting indicated that the small, bright, and narrow emissive CL-BODIPY 565 Pdots are promising probes for biological applications.
以硼二吡咯亚甲基(BODIPY)聚合物为受体、聚[9,9-二辛基芴-2,7-二亚基-1,4-苯并-{2,1'-3}-噻二唑](PFBT)聚合物为供体,设计出了具有强烈且狭窄黄色发射的交联聚合物点。聚合物点(Pdots)的发射半高宽为37纳米。在相同实验条件下,CL-BODIPY 565 Pdots的亮度约为商用量子点(Qdots)565的5倍。特异性细胞靶向表明,小尺寸、明亮且发射狭窄的CL-BODIPY 565 Pdots有望成为生物应用的探针。
