AbstractAs an important photoconductive hybrid material, perylene/ZnO has attracted tremendous attention for photovoltaic-related applications, but generally faces a great challenge to design molecular level dispersed perylenes/ZnO nanohybrids due to easy phase separation between perylenes and ZnO nanocrystals. In this work, we reported an in-situ reaction method to prepare molecular level dispersed H-aggregates of perylene bisimide/ZnO nanorod hybrids. Surface photovoltage and electric field-induced surface photovoltage spectrum show that the photovoltage intensities of nanorod hybrids increased dramatically for 100 times compared with that of pristine perylene bisimide. The enhancement of photovoltage intensities resulting from two aspects: (1) the photo-generated electrons transfer from perylene bisimide to ZnO nanorod due to the electric field formed on the interface of perylene bisimide/ZnO; (2) the H-aggregates of perylene bisimide in ZnO nanorod composites, which is beneficial for photo-generated charge separation and transportation. The introduction of ordered self-assembly thiol-functionalized perylene-3,4,9,10-tetracarboxylic diimide (T-PTCDI)/ ZnO nanorod composites induces a significant improvement in incident photo-to-electron conversion efficiency. This work provides a novel mentality to boost photo-induced charge transfer efficiency, which brings new inspiration for the preparation of the highly efficient solar cell.

Transmission And Reflection

Optical transmission and reflection measurements are reported for the quasi one dimensional solids perylene-TCNQ (P1T1) and (perylene)3-TCNQ (P3T1) in the region from 300 to 1200 nm. Raman spectra of single crystals of both compounds were obtained from 20 to 3000 cm−1. With 457.9 nm excitation, combinations and overtones of perylene are observed for the first time. A complete Raman spectrum of perylene and its deuterated homologue including librations is thus obtained via selective resonance enhancement of that molecule.

We present the polarized reflection spectra of several MPcs ( M ≡ Co , Ni , Cu , Zn , Pb ) in the Q-band region and interpret them based on conventional exciton theory. We compare the polarized reflection spectra of the phthalocyanine radical salts NiPc ( AsF 6)0.5, H 2 Pc ( AsF 6)0.67 and LiPc and interpret the new absorption band near the Q-band using the relationship between the degree of oxidation and the intensity of this new band. Based on the pressure dependence of this new band and the diagnostic phonon modes, we prove a pressure-induced charge transfer in NiPc ( AsF 6)0.5. A metal–insulator phase transition is predicted from the analysis of the plasmon absorption and is confirmed by the high-pressure electrical resistivity. We propose the origin of the pressure-induced charge transfer and the mechanism of the metal–insulator transition. We find the optical transition associated with the 3 d z2 band in the reflection spectrum of CoPc ( AsF 6)0.5, which is proved by comparison with the mixed crystals Co x Ni 1 − x Pc ( AsF 6)0.5. A new weak intermolecular optical transition is found through the resonance enhancement of a local phonon in the mixed crystals Co x Ni 1 − x Pc ( AsF 6)0.5.
