N-(2,4,7-trinitrofluorenylidene)anilines—new electron transport materials in positive charge electrophotography

Abstract

New electron transport materials, N-(2,4,7-trinitrofluorenylidene)-2,6-dialkylanilines, show excellent properties in positive charge electrophotography. Single-crystal X-ray diffraction analyses of two of these compounds are reported. The high solubility of N-(2,4,7-trinitrofluorenylidene)-2,6-diethylanilines could be mainly attributed to the loss of overlap between intermolecular fluorene rings due to the bulkiness of the ethyl groups.
