进化（Evolution），这个词汇最能联想到达尔文有关自然界生物为了回应环境压力、自然选择和基因突变而逐渐（经过好几百万年）产生由低级到高级的发展变化过程。回顾单枪影院投影机的发展，数码工业化生产将这一进程微缩到不到10年的演变过程，从480p到720p再到1080p Full HD大约不到5年时间，而实际上早在2003年6月JVCD—ILA3840×2048像素数码投影机已开启4K时代。2004年6月SONy SXRD—R110已完成Digital Cinema 4096×2160的4Kp技术发展。

New acetylene monomers, 6-{[(1-naphthylethynyl-4-phenyl)carbonyl]oxy}-1-phenyl-1-hexyne (1), 2,5-diethynyl-thiophene (3), and 4,4'-diethynylbiphenyl (6) were synthesized. Homopolymerization of 1 and copolycyclotrimerizations of 3 and 6 with 1-heptyne and 1-octyne have been achieved with wCl6- and TaCl5-Ph4Sn catalysts, respectively, giving soluble linear disubstituted polyacetylene (2) and hyperbranched polyarylenes (5 and 8) with high molecular weights (up to 1.2 x 10(5)) in high yields (up to 98%). The structures and properties of the polymers are characterized and evaluated by R NMR, TGA, UV, photoluminescence (PL), and electroluminescence (EL) analyses. All the polymers possess high thermal stability and emit strong blue light upon photoexcitation. The intensity of the emitted light is greater than that of poly(1-phenyl-1-octyne), a well-known highly luminescent disubstituted polyacetylene. Little aggregation-induced red shift in the PL was observed in the thin films of the polymers. By constructing a multi-layer EL device, high EL quantum yield (0.18%) has been achieved in 2, which are the best results for substituted polyacetylenes attainable so far.

目标:分析活动期葡萄膜炎患者在小梁切除术后的炎症反应及眼压情况。方法:我们回顾了2006-10/2011-03期间,接受了小梁切除术的活动期葡萄膜炎性青光眼患者纪录。手术前后的炎症反应、复发频率、类固醇依赖度及眼压均以配对t检验作比较。结果:在29例29眼患者中,90%的患眼在手术时正在接受局部类固醇治疗。患者平均年龄为58.3±14.0a,术前眼压为35.7±8.9mmHg。患者平均复诊时期为35.2±18.7mo。术后3mo前房炎症反应分级平均减少了0.4±0.6(P<0.01)。复发频率在复诊期内每年减少了2.3±2.1次(P<0.01)。术后1a的平均眼压为13.1±4.5mmHg,而其中44.8%患者的眼压无需用药亦能维持在21mmHg或以下。结论:小梁切除术后的葡萄膜炎性青光眼患者在炎症反应及眼压方面均有改善,但成功率较原发性青光眼患者低。小梁切除术可以作为活动期葡萄膜炎性青光眼患者早期控制眼压和炎症反应治疗的一个选择。

稠(杂)环聚合物是一类重要的功能聚合物,因其优异的光电特性而被广泛应用于光电领域.这类聚合物的传统制备方法往往需要用到修饰有复杂官能团的稠(杂)环单体,这些单体种类有限且合成难度大,导致稠(杂)环聚合物的发展受到限制. C–H活化过程的发现与提出为利用惰性的C–H键作为潜在官能团提供了可能,有效避免了对单体进行复杂修饰的要求,大大扩增了单体的种类和来源.基于C–H活化的炔烃环化聚合反应,能够在聚合物骨架中原位直接形成稠(杂)环结构,具有原料简单易得、聚合效率高、产物结构丰富等诸多优势,因此受到广泛关注.本文分类总结了基于C–H活化的炔烃环化聚合领域的最新进展,包括合成手段和所得聚合物的性质与功能介绍,并对该领域的未来发展方向进行了展望.
