Abstract: Based on the simulation experiment it is discovered that the generation of fluorene series compounds on the biological precursors with the same structure. At a certain temperature, β carotene can transform into fluorene series and the reaction of sulphur with chain organic compounds can form more abundant fluorene series. While aromatizing, some changes such as methyl coming off, methyl removing and hydrogen of methyl coming off may take place in β carotene, which will form a great deal of free radicals, and the fluorene series will be formed when the free radicals form bond; The diphenyl methanes formed by β carotene may transform into fluorene series compounds; The reaction of sulphur with chain compounds forms possibly some diphenyl methanes at first, then sulphur acts on the products and seizes the α H of the two aromatic nuclei to form free radicals. When the free radical of one aromatic nucleus combines another one's, fuorene is formed. Although flourene series have the biological carbon skeleton, they should not be referred to as biomarkers for they were mainly formed by geochemical synthesis.
