A series of NIR organic chromophores with donor-pi-acceptor-pi-donor structure are synthesized. Good thermal stability and strong photoluminescence in solid state render them suitable for application in light-emitting diodes. Exclusive near-infrared emission at 1080 nm with external quantum efficiency of 0.28% is obtained from the nondoped OLEDs. The longest electroluminescence wave-length is 1220 nm.

大兴安岭摩天岭泥炭藓泥炭纤维素的δ13C 时间序列揭示了近1000 a 来该区气候的演变过程。区内1000 a 的气候经历了950700 a BP、700300 a BP 及300 a BP 以来三个阶段百年尺度的干湿波动,这些波动上又叠加了一系列数十年尺度的气候变化。该序列指示了大兴安岭地区近代气候向着偏干方向发展。
