摘要：J-aggregates of cyanine have shown great merits in tumor photothermal therapy(PTT)due to their distinct redshift absorption as well as superior photothermal conversion efficiency(PCE).However,due to the complexity of intermolecular interactions,especially the impact of steric hindrance on aggregation,exploring effective strategies to regulate the aggregation modes of organic materials remains ***,steric hindrance-regulated J-aggregation of near-infrared(NIR)cyanine was reported based on Pt-coordinated cyanine self-assembly with unexpected“butterfly effect”.Two Pt-coordinated cyanine dimers CyR-Pt(R=Me and Et)were synthesized and spontaneously self-assembled into aggregates in aqueous ***-Pt aggregates were loose and amorphous *** replacing ethyl with methyl to reduce steric hindrance,a tiny change resulted in the generation of tightly stacked cyanine J-aggregates(thickness less than 3 nm)observed in CyMe-Pt ***,this unexpected“butterfly effect”enabled CyMe-Pt J-aggregates to effectively inhibit reactive oxygen species and greatly improve its ***,CyMe-Pt J-aggregates with NIR-II absorption exhibited outstanding photothermal stability and higher PCE(η=37%)than CyEt-Pt disordered aggregates(η=20%).Evident tumor suppression performance of CyMe-Pt J-aggregates was validated under 980 nm laser irradiation,demonstrating its great potential in tumor PTT.

摘要：针对华电大同第一热电厂生活污水和生产废水的具体水质特点,采用了相应的处理方法。两股废水处理之后混合,经过多介质过滤、超滤、反渗透、加氨处理后回用,各项出水水质指标均明显低于《工业循环冷却水处理设计规范》的标准,基本实现了废水、固废的零排放。
