An 8-fold interpenetrating diamondoid network, [Ni(cyclam)] 2
[TCM] â
2DMF â10H 2
O, has been prepared by the self-assembly of a Ni-
(II)cyclam macrocyclic complex and sodium tetrakis[4-(carboxyphenyl)-
oxamethyl]methane in DMF/water. The network shows an unusual
[4 + 4] mode of interpenetration, generating 1D channels of
effective window size 6.7 Å × 4.7 Å. The network shows flexible
behavior: it becomes nonporous on removal of the guest molecules
occupying the channels, but the open structure is restored when
the desolvated solid is immersed in the mixture of H
2
O/DMF (1:1,
v/v) for 5 min. The desolvated host has different binding capacities
for n-butanol, pyridine, and ethanol.
Assembly of metal-organic open frameworks (MOFs) has
attracted great attention, and MOFs with various network
topologies have been prepared from the metal and organic
building blocks.They have the potential for being applied
to selective molecular recognition and separation,gasstorage,ion-exchange,
and heterogeneous catalysis.It is
of interest to build diamondoid networks with big cavities
because they have the perspective to be used as porous
materials or for a catalytic purpose. Interpenetrating dia-mondoid networks with open structures including counterions
and guest molecules have been demonstrated.
Our design strategy was to build a neutral diamondoid
network by interconnecting a big pseudotetrahedral anionic
ligand and a metal ion having two coordination sites at the
trans position (Scheme 1). We chose tetrakis[4-(carboxyphe-nyl)oxamethyl]methane (TCM) ligand

金属有机骨架(MOFs)自组装的极大关注,并与各种networktopologies MOFs材料已经从金属制备有机建造块。他们被用于选择性分子识别、分离,库,离子交换的潜力,和多相催化。它有兴趣建立与大cavitiesbecause他们作为porousmaterials或催化目的看钻石网络。互穿网络直径mondoid包括counterionsand客体分子的开放结构已被证明。我们的设计策略是由相互连接的一大anionicligand四面体和跨位具有两个配位点的金属离子的建立一个中立的diamondoidnetwork(方案1)。我们选择了四[ 4(carboxyphe NYL)oxamethyl ]甲烷(中医)配体

当爱向你招手的时候,跟着它
尽管道路会陡峭艰难
当它用翅膀将你包围的时候,不要逃避(挣扎),屈服于它
尽管里面藏着的剑会伤害到你
当它对你说话的时候,相信它
尽管它的声音会摧毁你的梦,就像北风肆虐花园
爱除了充实它自己之外并没有其他的追求
但是如果你爱着并且有追求,就让这些成为你的追求
“去了解爱的痛苦
去被你自己对爱的理解伤害
去开心快乐的流血心痛
在黎明醒来,心像插着翅膀,给新的一天的爱
在中午的时候休息一下思考爱情的喜悦
在黄昏的时候带着感恩的心情回家
然后 为心中所爱的人的祈祷,唱着赞美的诗歌 入睡”
看上去很有宗教色彩
好晦涩难懂啊
大概就这意思,用词不妥请谅解
