| Abstract | Multilayer films of oligo(pyrenebutyric acid) (OPB) and N,N'-bis(N,N-dimethylaminopropylaminopropyl)-3,4,9,10-perylenediimide (BDMAPAP-PDI) were successfully fabricated by layer-by-layer deposition. Multilayer growth was monitored by ultraviolet-visible (UV-vis) spectroscopy, fluorescence spectroscopy, ellipsometry, and atomic force microscopy (AFM). It was found that extraction was scarcely observed although both components (OPB and BDMAPAP-PDI) have low molecular weights and both electrostatic interactions and pi-pi stacking contributed to the multilayer deposition. The multilayers exhibit a rapid photocurrent response, and excitations of both OPB and BDMAPAP-PDI can lead to the effective charge dissociation. The incident photon to current conversion efficiency (IPCE) of the composite film with 5 bilayers was measured to be 1.29% at the absorption peak of BDMAPAP-PDI. Fluorescence quenching and photovoltaic conversion studies indicated that strong photoinduced charge transfer interactions occurred at the area of OPB/BDMAPAP-PDI heterojunction in the films, which strongly enhanced the photoresponse of the multilayer films. |
