SYNTHESIS AND PROPERTIES OF FLUORENE BASED SMALL MOLECULE ACCEPTORS CONTAINING AROMATIC MALONONITRILE FUNCTIONALITIES

Synthesis and properties of fluorene based small molecule acceptors containing aromatic malononitrile functionalities

Four novel small molecule acceptors (SMA) with fluorene-based cores were synthesized with terminal phenyl, thienyl, and furyl malononitrile groups in good yields.The products were obtained from a two-step reaction of 2,2′-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) with m- or p-bromobenzaldehyde, 5-bromo-2-thiop
