Usage

General Description

9,9-dibutyl-2-nitro-9H-Fluorene is a chemical compound belonging to the group of organic compounds known as fluorenes. These are polycyclic aromatic compounds containing a fluorene moiety, which consists of two benzene rings linearly fused to a nine-membered cyclopentane ring. The "9,9-dibutyl" signifies that there are two butyl groups attached to the ninth carbon in the compound's structure while "2-nitro" indicates the presence of a nitro group on the second carbon. 9,9-dibutyl-2-nitro-9H-Fluorene has been used in scientific research, particularly in the area of organic semiconductors, due to its unique properties.
