The effect of dextrans on Photoconductive Perylene Bisimide Gels
Perylene bisimides (PBIs) are interesting materials for the use in organic electronics. This is due to them being able to accept an electron in response to light and form the radical anion. We have recently found that the addition of dextran or a simple sugar can increase the lifetime of this radical anion due to them being able to interact with the PBI structures. From EPR we can see that there is a difference in the radical anion produced in the PBI system versus the PBI + dextran systems. We want to investigate using SANS whether this is caused by a structural change in the PBIs when the dextran or sucrose is added making the radical anion more stable.
