Materials show a trend in expansion of their volume when the temperature increases. The thermal expansion pathways are broadly classified into two types: one is a gradual thermal expansion over a wide temperature range, and the other is a huge thermal expansion over a narrow temperature range. On the other hand, the thermal expansibility of organic crystals is of interest due to their densely packed and ordered molecular structure. However, there are few systems in which the organic crystal shape is controllable in heating and cooling. Here, we report on anthracene crystals that show giant thermal expansion in a narrow temperature range.
