2,5,8,11-Tetraalkenyl Perylene Bisimides: Direct Regioselective Synthesis and Enhanced π–π Stacking Interaction
A series of 2,5,8,11-tetraalkenyl
perylene bisimide (PBI) derivatives
were synthesized through RuÂ(II)- or RhÂ(III)-catalyzed regio- and steroselective
oxidative C–H olefination in one step. The optical electronic
and self-assembly of the 2,5,8,11-substituted PBIs were investigated,
which showed great potential in optoelectronic applications
Direct Synthesis of Large-Scale <i>Ortho</i>-Iodinated Perylene Diimides: Key Precursors for Functional Dyes
A highly regioselective
tetra-<i>ortho</i>-iodination
reaction of perylene diimides (PDIs) has been developed, which could
be conducted on a multigram scale (>10 g), featuring a column chromatography-free
workup and purification. The <i>ortho</i>-iodinated-PDIs
serve as key intermediates for the preparation of a variety of <i>ortho</i>-functionalized PDIs and PDI-based conjugated polymers
