The kinetic decays of photoconductivity of HDPPBA-C and HDPPBA-N showed that the photogenerated free charge carriers are stable for more than 10 s, meaning that the supramolecular structures have 10-fold long charge carrier lifetime by the incorporation of H-bonds compared to the control. This is translated in faster charge recombination for the control molecule, HDPPH. Additional measurements were performed by extending the time window up to 100 s and interestingly, the charge carrier lifetime of HDPPBA-N was one order of magnitude longer than the one of HDPPBA-C, finding values of 3.7 x 10 -5 s and 1.6 x 10 -4 s, respectively (Figure and Table , entries 4 and 5). These results show that the subtle difference in amide topology plays an important role in the self-assembly process of both derivatives, and thus, in the electrical performance. Furthermore, we have observed that the charge carrier lifetime of the H-bonded structures is extraordinarily long, being at least of one order of magnitude larger than similar H-bonded systems measured by FP-TRMC and reported in the literature. In our case, the amide groups are separated from the -conjugated segment by a flexible alkyl linker, while in the other examples reported in literature, the amide bonds are directly attached to it. By placing the amide bonds between two flexible alkyl linkers, it is possible to obtain supramolecular structures with long charge carrier lifetimes.
