Trichlorobenzene-graphite

Fig.22 Molecular models and corresponding STM images of Kagom network (DBAl) (20.0nmx20.0nm) and Honeycomb network (DBA2) (18.7 nmxl8.7 nm) recorded at the 1,2,4-trichlorobenzene-graphite interface. (Reproduced with permission from [62])...

Fig. 23 A Chemical structure of a DBA derivative with alkoxy chains and cartoon demonstrating the transition from a porous honeycomb structure to a dense packing upon elongation of the alkyl chains. B Guest-induced transition from a dense network to a honeycomb network. The graph shows the honeycomb coverage as a fimction of the guest (g) to host h) ratio. STM images (96nmx96nm) recorded at the 1,2,4-trichlorobenzene-graphite interface for different guest to host (g/h) ratios. (Reproduced with permission from [66])...

Summary of Known Methods of Ereparation of Mesophase. At the time of writing, it appears that a major objective of research into the chemistry of mesophase formation is to obtain mesophase at as low a temperature as possible and to have a soluble mesophase, e.g. in 1,2,4 trichlorobenzene (112). The applications of such mesophase(s) must be in the production of graphitizable pitch fibres. However, this direction of research could have applications in many other areas of carbon/graphite production. Therefore it is appropriate, now, to make a list of known methods of preparation of mesophase (113).

Monolayers of cyclothiophene macrocycles have been observed to form a complex with Cgo molecules, when studied with STM at a 1,2,4-trichlorobenzene solution/ graphite interface [13].
