“…͑See Scheme I.͒ Furthermore, it was demonstrated that mixture targets of PTCDA with metal powders such as Co ͑PTCDA/Co͒ led to increase the yield of ''naked'' perylene skeletons without side groups of PTCDA by improving the efficiency of elimination of the groups by catalytic effect of Co, resulting in more effective preparation of PPN nanoparticles. 7 In this article, optimized ablation conditions have been determined for preparation of better defined PPN nanoparticles by ELA of PTCDA and/or mixture targets of PTCDA with TiO 2 as well as Co powders expecting further catalytic effect. Furthermore, from the practical aspects of the PPN nanoparticles prepared by ELA, pn junctions consisting of a͒ Electronic mail: nishio@orgphys.chem.tohoku.ac.jp the PPN nanoparticle layer and Si wafers have been fabricated for the purpose of applying them to an organic photovoltaic cell.…”

Polyperinaphthalene (PPN) nanoparticles are prepared by excimer laser ablation (ELA) of a 3, 4, 9, 10-perylenetetracarboxylic dianhydride (PTCDA) target or a mixture target of PTCDA with Co or TiO2 powder (PTCDA/X: X=Co, TiO2) using XeCl excimer laser beams. Enhancement of elimination reaction of side groups of PTCDA is observed by ELA of PTCDA/Co and PTCDA/TiO2. In particular, for PTCDA/TiO2, the reaction occurs at a fluence of 0.25 J cm−2 pulse−1 much lower than the case of PTCDA/Co at room temperature. Heterojunctions between the PPN nanoparticle layer and Si wafers are formed. Well rectifier property is demonstrated for the junction with n-Si substrates. Current versus voltage curve of the heterojunction with a n-Si substrate in the dark and under illumination shows the possibility of the junction as a photovoltaic cell. Furthermore, PPN nanoparticles are applied to anode electrodes for ultrathin rechargeable Li ion batteries. In situ Raman spectroscopy under lithium ion doping is performed to elucidate the storage mechanism of lithium ion at cis-polyacetylene-type edge (phenanthrene-edge) of PPN structure.

Heterojunctions of PPN films prepared by ELA of PTCDA with Si wafers are fabricated. Well rectifier property is obtained for the junction of the PPN with a n-Si substrate. Current versus voltage curves of the heterojunction in the dark and under illumination show that the junction is promisimg as a photovoltaic cell. Furthermore, PPN films are applied to anode electrodes for ultra thin rechargeable Li ion batteries. Substrate temperature dependence of effective capacitance of lithium ions at first cycle are investigated. In addition, in-situ Raman spectroscopy of the films under lithium ion doping and undoping is performed to elucidate the storage mechanism of lithium ion at cis-polyacetylene-type edge (phenanthrene-edge) of PPN structure.
