Fusion of perylene bisimides and hexaazatriphenylene into a star-shaped ladder conjugated n-type semiconductor†
Abstract
Novel n-type star-shaped molecule TriPBI containing a HAT core and three fused PBI “arms” was synthesized and characterized. The n-type charge carrier mobility as high as 3.34 × 10−3 cm2 V−1 s−1 of TriPBI is evaluated by SCLC measurements, which is considerably higher than 8.71 × 10−5 cm2 V−1 s−1 of the PBI monomer.
