Electron Delocalization in Perylene Diimide Helicenes.

We report two new helicenes derived from the double fusion of an acene with two perylene diimide (PDI) subunits. These PDI-helicene homologs exhibit very different structural and electronic properties, despite differing by only a single ring in the link between the PDI units. The shorter inter-PDI link brings the two PDI subunits closer together, and this results in the collision of their respe...

Persistent Photoconductivity in Perylene Diimide Nanofiber Materials

Perylene tetracarboxylic diimide (PTCDI) derivatives have been extensively investigated for one-dimensional (1D) self-assembly and their applications in optoelectronic devices. Our study on self-assembled PTCDI nanofiber materials revealed a persistent photoconductivity (PPC) effect, which is sustained conductivity after illumination is terminated. A comprehensive understanding of the PPC effec...

Crystal structure of N,N′-di­benzyl­pyromellitic diimide

The title compound, C24H16N2O4 [systematic name: 2,6-di-benzyl-pyrrolo-[3,4-f]iso-indole-1,3,5,7(2H,6H)-tetra-one], consists of a central pyromellitic di-imide moiety with terminal benzyl groups at the N-atom positions. The mol-ecule is located about an inversion centre, so the asymmetric unit contains one half-mol-ecule. In the mol-ecule, both terminal phenyl groups, tilted by 72.97 (4)° with ...

Fluorescence quenching in a perylenetetracarboxylic diimide trimer.

A perylenetetracarboxylic diimide (PDI) trimer (3) linked by a triazine ring has been prepared. The UV-vis absorption spectra together with the (1)H NMR spectra revealed that two of the three PDI subunits in the trimer presents a face-to-face stacked configuration while the third one appended acts as a monomer. There is no strong interaction between the dimer and monomer at ground state. Howeve...
