Dispirofluorene-indenofluorene (DSFIF): Synthesis, Electrochemical, and Optical Properties of a Promising New Family of Luminescent Materials
摘要:
A series of new dispiro[fluorene-9 ',6,9 '',12-indeno[1,2b]fluorenes] (DSFIFs) that combine indenofluorene (IF) and spirobifluorene (SBF) architectural specificities have been prepared. Their anodic oxidations lead to the formation of nonsoluble transparent polymers. The photophysical and electrochemical properties of these new molecules have been evaluated for further blue OLED applications.

A series of new dispiro[fluorene-9',6,9'',12-indeno[1,2b]fluorenes] (DSF-IFs) has been synthesised. These newbuildingblocks for blue-light-emitting devices and electroactivepolymers combine indenofluorene (IF) and spirobifluorene (SBF) properties. We report here our synthetic investigations towards these new structures and their thermal, structural, photophysical and electrochemical properties.

Two new crystallinehostcompounds of bisfluorenol type featuring an elongated core structure compared to a known parent molecule (2,2′′-[1,1′:4′,1′′]-terphenylyl versus 2,2′-biphenylyl) have been synthesized. Crystallineinclusioncompounds involving protic guest molecules have been prepared and studied with reference to their crystal structures. Conformational changes as against the prototype compound
