Synthesis and Fluorescence Emission Properties of 1,3,6,8-Tetrakis(9H-Fluoren-2-yl)Pyrene Derivative

A novel pyrene-based highly pure blue fluorescent and stable molecule, 1,3,6,8-tetrakis[9,9-bis(3-methylbutyl)-9H-fluoren-2-yl]pyrene, was successfully synthesised via a Pd-catalysed Suzuki coupling reaction of 1,3,6,8-tetrabromo-pyrene with 2-[9,9-bis(3-methylbutyl)-9H-fluoren-2-yl]-4,4,5,5-tetrame...

Description
Summary:A novel pyrene-based highly pure blue fluorescent and stable molecule, 1,3,6,8-tetrakis[9,9-bis(3-methylbutyl)-9H-fluoren-2-yl]pyrene, was successfully synthesised via a Pd-catalysed Suzuki coupling reaction of 1,3,6,8-tetrabromo-pyrene with 2-[9,9-bis(3-methylbutyl)-9H-fluoren-2-yl]-4,4,5,5-tetramethyl[1,3,2]dioxaborolane. The photoproperties of this pyrene were examined in detail and these data indicated its potential application as blue-emitting materials in organic light-emitting diodes.
