| Abstract |
Recently, serial femtosecond crystallography (SFX) which is an arising crystallography technique, has attracted interests of various scientific fields. SFX utilizes highly bright and temporally short X-ray pulses generated from an X-ray free electron laser (XFEL). Thanks to the brightness of the X-ray, SFX employs a serial scheme in which a crystal is disposed or removed after a single exposure to an X-ray pulse, unlike conventional crystallography. With the aid of the serial scheme and ultrashort temporal width of the X-ray, SFX has been used to determine crystal structures without damage caused by X-ray. However, the application of SFX was focused on macromolecules such as proteins, even though SFX on a small molecule system has sufficient potential. Here, we present the results of X-ray diffraction image collection of a small molecule system (1,4-diiodobenzene) using SFX conducted at PAL-XFEL which is a new XFEL facility located in Pohang, Korea. The microcrystals of 1,4-diiodobenzene were dispersed in lipidic cubic phase (LCP) and delivered to the position where X-ray irradiates for diffraction. From the experiment, we verified that the serial X-ray diffraction image collection of a small molecule system was successful. This results will be a key for studying the structural dynamics of the organic halide using time-resolved serial femtosecond crystallography (TR-SFX) which can visualize the structural change in a crystal along time. |
