Since delocalized π electrons can move about throughout a crystal or molecule without distorting it, π-electron materials have many peculiar characteristics such as extremely high electron mobility and superpolarization. The π-electron cloud is also a fundamental reaction field for organic and biological materials.The Yoshimura π-Electron Materials Project will view the large space occupied by the freely-moving π electrons as domains of electron motion and materials transformation. The project will exploit and elucidate unique physical, chemical and biochemical phenomena which result from these domains. For this, the project will develop synthetic methods and processes for new organic and inorganic materials with extended π-electron systems and with high crystallinity. It will elucidate the mechanisms of superpolarization, high electron mobility and nonlinear phenomena. The project may propose new electronic devices based on unique features of π electrons. Other work will focus on selective and/or anomalous reactions in which the π-electron domains participate. This work may shed light on mechanisms of biocompatibility and proliferation on carbonacious materials in relation to electronic structures of the π-electron systems.

It was reported that a photovoltaic cell with carbonaceous film/n-type silicon (C/n-Si) was fabricated utilizing a process in which a carbonaceous film was deposited on an n-type silicon substrate by chemical vapor deposition (CVD) of 2, 5- dimethyl-p-benzoquinone at 500°C The purpose of this work is to study preparation and structure of the carbonaceous film. In this study, the carbonaceous films were made by CVD of 2, 5-dimethyl-p-benzoquinone on a quartz substrate at a temperature between 500 and 1000°C. The 2, 5-dimethyl-p-benzoquinone shows higher reaction activity for carbonization at low temperatures. At low CVD temperatures below 700°C, the carbonization reaction of 2, 5- dimethyl-p-benzoquinone was mainly caused by pyrolysis of its methyl and carbonyl groups. The carbonaceous film deposited at low temperatures below 700°C has a typical amorphous structure, and the one deposited above 700°C has a graphite-like lamellar structure oriented along the substrate.
