对储能材料的探索促进了新材料的合成，这些新材料是在可控条件下通过热解芳香前体获得的，用于生产以氢或锂存储为目的的碳基结构无序网络。显然，这些材料是由不同分子种类的完全不溶的混合物组成的，它们逃避了传统的物理化学技术来确定结构。为了克服这一困难，我们开发并报告了一个系统的振动光谱工作，它奠定了在研究分子的结构理解中要考虑的基本概念，并可以扩展到类似类别的复杂碳质材料。这些体系的（部分）结构和分子水平上的一些反应途径可以从提出和讨论的光谱信号中推断出来，并作为结构分析的关键特征。(c) 2005 Elsevier Ltd版权所有。
The search for materials aimed at energy storage has prompted the synthesis of new materials which were obtained by pyrolysis of aromatic precursors under controlled conditions for the production of carbon based structurally disordered networks aimed at hydrogen or lithium storage. Obviously these materials consist of fully insoluble mixtures of different molecular species which escape the traditional physico-chemical techniques for structure determination. With the purpose of overcoming this difficulty we have developed and report here a systematic vibrational spectroscopic work which lays the basic concepts to be considered in the structural understanding of the molecules studied and can be extended to similar classes of complex carbonaceous materials.The (partial) structure of these systems and some of the reaction pathways at the molecular level can be inferred from the spectroscopic signals presented and discussed to be taken as key features for structural analysis.
