We propose that a new and potentially extensive class of solid
polymeric materials with unprecedented and possibly useful
properties may be afforded by linking together centers with either
a tetrahedral or an octahedral array of valencies by rod-like
connecting units. For example, if ways could be devised of linking
together tetrahedral centers and appropriate molecular rods, an
infinite molecule would be generated which might be expected
to adopt a structure based on either the cubic diamond lattice or
the hexagonal Lonsdaleite lattice in which each C-C bond of the
prototype had been replaced by a molecular rod. These frameworks
would generate a regular array of cavities, interconnected
by windows. When models of 3D networks based on tetrahedral
centers are constructed, a very striking feature is the relatively
large size of the cavities and windows produced even by rods of
only modest length.
Lattices of this general type seemed to us to offer a number
of features of sufficient potential interest and utility to warrant
attempting the synthesis of some exploratory examples. For
instance, they may show interesting molecular sieve and ion exchange
properties, they may have unusual mechanical and elec-trical properties, and they may, after appropriate functionalization
of the rods, provide tailor-made materials for the heterogeneous
catalysis of a wide range of transformations.

第一段的译文,仅供参考,因为不是学晶体和材料的,所以有点拗口。
我们发明了一种新的大分子固体聚合材料,由四面体或者八面体棒状连接单元连接起来的这种材料具有前所未有的性能。例如当份额该材料分子被设定以四面体和相适应的分子棒连接时,就可以产生一种立方晶格或者六方晶格的大分子结构,晶格原型的每个C-C键都是该中大分子的分子棒。这种分子骨架能够产生分子管状相互连接的规则的腔。当这种基于3D网状结构形成后,显著的性质就是大尺寸的腔,这种管状腔甚至可以由较小的尺寸分子棒产生。

这种晶格材料可以为我们提供许多完成开发项目有效的合成保证。例如,该类材料可能显示出很由意思的分子筛和例子交换性能,也可能显示不同寻常的机械和电子性能,当然,在得到合适的功能整理后,也有可能成为异相催化转化的尾接材料。
