Looking at crystal structures makes us feel as if we are in a museum. Molecules are self‐assembled to form beautiful crystal structures. Herein, bis(dioxaborin) compounds containing 2,2′‐bithiophene derivatives were synthesized as n‐type semiconductors for organic field‐effect transistors (OFETs). An OFET fabricated using one of these compounds having a layer‐by‐layer crystal structure exhibited n‐type semiconductor behavior with a low threshold voltage. This OFET performance was studied by theoretical calculations based on the crystal structure. More information can be found in the Full Paper by Katsuhiko Ono et al.

University) Tetsuo MIYAZAWA (Aichi University) Keiji SUZUKI (Municipal Government of Hamakita City)The purpose of this study is not only to describe the climate of Nishio city, but also to make an insight into the substantial structure of heat island phenomena by giving an example of Nishio city . So it is required to make the maps of energy balance in an urban area of Nishio city. For this purpose, the two methods were adopted; one was to make clear the diurnal variation of urban temperature, another to investigate the heat island phenomena seen on the ground temperature in and around an urban area. Finally, the factors causing the urban climate of heat island were considered by investingating the structures of the buildings in the city, that is, the materials and the height of the buildings, soil moisture, surface cover of the earth or etc., Fig.13 indicates the distribution of the soil moisture shown with the depth of the ground water. The relationship between soil temperature and surface cover of the earth is shown in Fig. 14.
