摘要：为认真贯彻落实乡村振兴战略规划,各地区结合实际,积极响应开展古村镇保护,众多专家学者也持续关注传统乡土景观的保护。绍兴市作为历史文化名城,具有较为丰富乡村景观资源。通过整理分析绍兴乡土文化元素,凝练出适宜当地乡土景观发展的原则,结合中国传统美术理论著作《画品》与现代油画作品《鲁迅故乡》,总结出较为新颖的景观艺术表达手法,打造非传统意义上的乡村空间,探索乡村发展的新模式,带动多种经济产业的开发。

摘要：Achieving high-efficiency deep blue emitter with CIE_(y)10%has been a long-standing challenge for traditional fluorescent materials in organic light-emitting diodes(OLEDs).Here,we report the rational design and synthesis of two new deep blue luminogens:4-(10-(4’-(9 H-carbazol-9-yl)-2,5-dimethyl-[1,1’-biphe nyl]-4-yl)anthracen-9-yl)benzonitrile(2 M-ph-pCzAnBzt)and 4-(10-(4-(9 H-carbazol-9-yl)-2,5-dimethyl phenyl)anthracen-9-yl)benzonitrile(2 M-pCzAnBzt).In particular,2 M-ph-pCzAnBzt produces saturated deep blue emissions in a non-doped electroluminescent device with an exceptionally high EQE of 10.44% and CIE_(x,y)(0.151,0.057).The unprecedented electroluminescent efficiency is attributed to the combined effects of higher-order reversed intersystem crossing and triplet-triplet up-conversion,which are supported by analysis of theoretical calculation,triplet sensitization experiments,as well as nanosecond transient absorption *** research offers a new approach to resolve the shortage of high efficiency deep blue fluorescent emitters.
