Abstract

original image

A new generation of spiro type molecule 2,2′,6,6′-Tetraphenyl-4,4′-spirobi[cyclopenta[2,1-b;3,4-b′]dithiophene, Spiro-4P-CPDT (see figure) has been synthesized and characterized. The optical, electrochemical, and electrical properties are very different with respect to its 9,9′-spirobifluorene analogue, Spiro-Quaterphenyl. This new compound with less aromatic heteroaryl unit as the core is a promising candidate as an amorphous charge transport materials in organic electronics.
