    Welcome to ICCOSS 2015, the 22nd International Conference on the Chemistry of the Organic Solid State. The Conference will be held from July 12th to 17th 2015 at Toki Messe in Niigata, Japan.

    Since the very first ICCOSS conference, held at Brookhaven (USA) in 1968, and following the sequence of highly successful conferences organized in subsequent years, ICCOSS has become firmly established as the premier series of international conferences on the chemistry and physics of organic materials.
    The scientific program will include plenary and special lectures, together with contributed lectures and poster sessions. An exhibition of scientific equipment, electronic resources and books will also be held.
