GRAPHITIZATION OF ORGANIC COMPOUNDS .2. X-RAY PROPERTIES OF CARBONS PREPARED FROM A SERIES OF ALKYLATED CARBAZOLES

The synthesis, carbonization, and graphitization of a series of carbazole derivatives, substituted at the ring carbon atoms by one or more methyl, ethyl, or butyl groups, are described. The carbons prepared from these compounds become more graphitic, as measured by X-ray crystallographic data, with increasing alkyl substitution and with increasing chain size of the alkyl groups. © 1969.
