被引用回数：3 パーセンタイル：17.59(Instruments & Instrumentation)Small angle neutron scattering (SANS) is a versatile and convenient method to investigate the higher order structure of molecular assembly systems. However, the more complicated a system of interest, the more difficult the interpretation in the SANS profile. In order to increase the reliability of structural analysis on a complicated system, it is desirable to obtain different kinds of structural information from the same sample simultaneously. Polarized infrared spectroscopy is able to provide information about the molecular structure, concentration, and orientation of each chemical species in a system. In order to utilize these advantages of polarized infrared spectroscopy, a simultaneous measurement system was built by incorporating a Fourier transform infrared (FTIR) spectrometer into a time-of-flight small angle neutron scattering instrument covering a wide Q range.

被引用回数：0 パーセンタイル：0.14(Polymer Science)Syndiotactic polystyrene (sPS) forms cocrystals with a wide range of chemical species from low-mass molecules to polymeric compounds, such as polyethylene glycols. Although the sPS lattice has been confirmed to accept linear compounds, such as n-alkanes and n-fatty acids, branched molecules have not been regarded as guests until now. To investigate whether sPS can adopt branched molecules as guests, cocrystallization using three types of monoacid triacylglycerols (TAGs) with relatively short acyl chains, tricaprin, trilaurin, and trimyristin has been attempted. Moreover, the sPS films subjected to the guest exchange procedure have been investigated via X-ray diffraction, Fourier transform infrared spectroscopy, and simultaneous small- and wide-angle neutron scattering. The results showed that sPS forms the monoclinic delta clathrate cocrystal with all the three TAGs.
