Between sulfuric acid and iron chloride both of which are acceptor-type intercalates, the criteria of host carbon materials were found to be different. In the case of iron chloride, host criterion for the intercalation in organic solution was also diferent from that through vapor.The determining factor for the intercalation of alkali metal-ether complexes was found to be the structure of host carbon materials, but also their texture, either coke of pyrolytic carbon, has prominent effect for the intercalation reaction. For Na-THF complexes, the cokes heat-treated at relatively low temperatures gave so-called random stage structure, but from the pyrolytic carbons stage-1 structure was obtained. For Na-DME complexes, however, such as host effect was not observed and all host carbons gave the compounds with stage-1 structure. This result suggested that not only Na ions but also the combination with ether molecules causes the host effect. In MeTHF solution, either ternary compounds with alkali metal-MeTHF or binary compounds with alkali metal was obtained, depending on the host carbon materials used.Limiting to the intercalation reactions in the solutions at room temperature, which were studied in the present research, the intercalation reaction was shown to be governed by different factors, such as host carbon materials, intercalates and solvents.

硫酸和氯化铁都是受体型插层剂，它们的主体碳材料的标准不同。在氯化铁的情况下，有机溶剂中插层的主体标准也不同于水蒸气中插层的主体标准，碱金属-醚配合物的插层反应的决定因素是主体碳材料的结构，但其结构（焦炭或热解碳）对插层反应也有显著影响。对于Na-THF络合物，在相对较低的温度下热处理的焦炭得到所谓的无规阶段结构，但从热解碳得到阶段-1结构。而对于Na-DME配合物，没有观察到主体效应，所有主体碳都具有第一阶段结构。这一结果表明，不仅Na离子，而且与醚分子的结合引起的主机效应。在MeTHF溶液中，根据主体碳材料的不同，可以得到碱金属-MeTHF三元化合物或碱金属-MeTHF二元化合物，但仅限于本研究中所研究的室温下的插层反应，插层反应受不同的因素如主体碳材料、插层剂和溶剂的影响。
