Regioselective Photocyclization To Prepare Multifunctional Blocks for Ladder-Conjugated Materials
摘要:
Multifunctional building blocks 8 and 9 were efficiently synthesized by fusing a perylene-3,4,9,10-tetracarboxylic acid bisimide (PBI) core with o-phenylenediamine, and they were condensed with a pyrenedione and a pyrenetetraone, respectively, to construct new ladder-type conjugated oligomers 12 and 13. In the key photocyclization step, an unusual regioselectivity at the position ortho to the nitro group was discovered in the coupling of the o-nitroaniline functional units at the bay sites of PBI. Bulk-heterojunction solar cells based on 12 and 13 as the acceptors exhibited reasonable performance.

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.
