Aggregation-Induced Emission of Curcuminoid-BF Complex for Phosphor-Converted Red Light-Emitting Diode.

The incorporation of difluoroboron β-diketonate and tetraphenylethene under a facile Knoevenagel condensation reaction afforded one new D-π-A-π-D complex with high aggregation-induced emission (AIE) activity. The film can maintain a high photocurrent after long-term (500 min) photoelectronic measurements. The successful fabrication of a red LED device makes it a promising candidate for high-performance solid-state lighting.

Evaluation of background persistent organic pollutant levels in human from Taiwan: polychlorinated dibenzo-p-dioxins, dibenzofurans, and biphenyls.

This study was intended to determine the background levels of PCDD/PCDFs and PCBs in the Taiwanese population and to investigate factors potentially related to PCDD/PCDF and PCB levels. The levels of seventeen PCDD/PCDFs in the 251 serum samples collected from the general population in Taiwan ranged from 4.92 to 26.

Congener profiles of PCBs and PCDD/Fs in Yucheng victims fifteen years after exposure to toxic rice-bran oils and their implications for epidemiologic studies.

In 1978-1979, a mass poisoning occurred in central Taiwan from rice-bran oil contaminated by heat-degraded PCBs was later called the Yucheng (oil disease in Chinese). Only a few studies have so far investigated the levels of specific polychlorinated biphenyl (PCB) or polychlorinated dibenzodioxin/furan (PCDD/F) congeners in the Yucheng victims. This study aimed to investigate the serum residual levels of thirty-three PCBs and seventeen 2,3,7,8-substituted PCDD/F congeners in the Yucheng victims 15 years after the exposure.
