摘要:摘要 并五苯是有机电子领域的重要半导体.在这项工作中,提出了一种从 6,13-并五苯醌作为前体获得并五苯的替代合成程序.并五苯的合成在两个反应中进行,6,13-并五苯醌的 Diels-Adler 环加成,然后 6,13-并五苯醌还原为并五苯,使用 Lialh4 作为还原剂.产物通过傅里叶变换红外光谱 (Ftir),1H-核磁共振光谱 (1H-NMR),X 射线衍射 (Xrd),热重分析 (Tga) 和紫外-可见光谱 (Uv-Vis) 进行表征.在这项工作中,使用替代方法以高产率 (55%) 合成了 6,13-并五苯醌.优化过程导致反应时间的整体减少,同时表现出高产率.

摘要:Apparatus for plasma synthesis of graphitic products including graphene, comprising: a plasma nozzle coupled to a reaction chamber; means for supplying a process gas to the plasma nozzle, the process gas comprising a carbon-containing species; and means for supplying radio frequency radiation to the process gas within the plasma nozzle, so as to produce a plasma within the nozzle in use, and thereby cause cracking of the carbon-containing species; wherein the plasma nozzle is arranged such that an afterglow of the plasma extends into the reaction chamber, the cracked carbon-containing species also passes into the reaction chamber, and the cracked carbon-containing species recombines within the afterglow, so as to form graphitic products including graphene. A method of plasma-synthesising graphitic products including graphene is also provided.

标题 :Convergent synthesis of multiporphyrin light-harvesting rods
发明人：LINDSEY JONATHAN S; LOEWE ROBERT S
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A 1 (A b+1 ) b , wherein b is at least 1, A 1 through A b+1 are covalently coupled rod segments, and each rod segment A 1 through A 1+b comprises a compound of the formula X 1 (X m+1 ) m wherein m is at least 1 and X 1 through X m+1 are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.
