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.
A meta-dielectric film usable in a capacitor includes composite molecules with a resistive envelope built with alkyl oligomeric single chain or branched chain oligomers having carbo-hydrogen or carbo-fluoro composition and a polarizable core molecular fragment inside the resistive envelope. The polarizable core has an electronic or ionic type of polarizability provided by electronic conductivity of the core molecular fragment or limited mobility of ionic parts of the core molecular fragment.

A novel perylenediimide molecule: Synthesis, structural property relationship and nanoarchitectonics
between perylene molecules, the morphology of nano-architectonics and absorption properties of compound 1 are investigated by DFT calculations. On the basis of molecular orbitals, we have explained the electronic transitions and energy state in compound 1. The conjugation in compound 1 is affected by the degree of twisting in perylene ring due to the substituent at the baypositions of the perylene core
