Cyclen-functionalized perylenediimides PBI-1 and PBI-2 were first synthesized as highly sensitive and selective fluorescent chemosensors for Pb2+ in aqueous solution. PBI-2 shows a better selectivity for Pb2+ in the presence of other metal ions and, importantly, it can successfully enter the cell and be applied in imaging of living cells.

N-Alkyl-3,4-perylenedicarboximides (alkyl=methyl, ethyl, propyl, butyl, isobutyl, pentyl, hexyl, and octyl) were prepared by the decarboxylation of N-alkyl-3,4:9,10-perylenetetracarboxylic monoanhydride monoimides (same alkyls) in potassium hydroxide solution.

Here we have shown that it is possible to modulate hydrophobic and hydrophilic interactions to further adjust the supramolecular helicity by changing the length of an alkyl chain. These modulated supramolecular interactions have been translated to and observed in electrical conductivity, and provide a new pathway to construct a high-performance nanodevice.

Excitation energy transfer in perylene-3,4:9,10-bis(dicarboximide) (PDI) aggregates is of interest for light-harvesting applications of this strongly absorbing and π–π stacking chromophore. Here we report the synthesis and characterization of two PDI dimers in which the chromophores are covalently linked by a redox-inactive triptycene bridge in orientations that are cofacial (1) and slip-stacked along

The condensations of 3,4 : 9,10-perylenetetracarboxylic dianhydride with alkylamines (isobutyl-, pentyl-, hexyl-, and octylamines) were spectroscopically determined. Under all of the reaction conditions employed, N-alkyl-3,4 : 9,10-perylenetetracarboxylic monoanhydride monoimide (2a–d) (alkyl=a; isobutyl, b; pentyl, c; hexyl, d; octyl) were obtained. As the reaction proceeded, the yield of 2a–d increased at an initial stage but decreased gradually after reaching a maximum. This maximum yield of 2a–d was: 2a; 85–88%, 2b; 85–89%, 2c; 78–84%, 2d; 79–85%. The kinetics of the reaction were also examined.
