The shear stress effect has been studied in order to introduce it to materials science for organic materials and molecular crystals. We have used the sapphire anvil cell to generate shear stress by the rotation of the lower anvil under pressure and performed the in situ observations under a microscope with spectroscopic measurements.1.Preparation of TMPD-TCNQ charge-transfer saltWe have attempted the syntheses by shear deformation. On applying the shear stress on TMPD N,N,N',N'-tetramethyl-p-phenylenediamine, colorless) and TCNQ (orange) films, the color at the outer part on the culet changed to blue-black. From the Raman spectra, the formation of TMPD-TCNQ CT salt at the blue-black part was confirmed.2.Shear stress effect on Pt(dpg)_2, bis(diphenylglyoximato) platinum(II)Pt(dpg)_2 is sensitive to the stress ; its color changes from red to green to yellow. We have studied the shear stress effect by Raman spectroscopy. The C=N bands at 1431 and 1452 cm^<-1> were shifted significantly by the shear deformation. The estimation of the effect was performed by their shifts in wavenumber. On applying the shear stress by the rotation of 10゜, the stress was increased from 0.14 GPa to 0.18 GPa at the center part and from 1.77 GPa to 2.41 GPa at the outer part. It was noted that the shear stress was applied more strongly at the outer part.3.Shear stress effect on Spiropyran 6-nitro-BIPSThe color of 6-nitro-BIPS at the outer part was changed from orange to green under shear deformation. As being released from the stress, it changed from green to purple. Because of strong fluorescence, the rotation-vibration Raman spectrum could not be obtained at the green part, while the spectra were measured at the orange and purple parts. This result suggests that 6-nitro-BIPS molecule under shear stress is different from one at ambient pressure.

已经研究了剪切应力效应，以将其引入有机材料和分子晶体的材料科学。我们已经使用蓝宝石砧室通过压力下的下砧旋转来产生剪切应力，并在显微镜下进行了具有光谱测量值的原位观测。在将剪切应力应用于TMPD N，N，N'，N'-四甲基-P-苯基二胺，无色）和TCNQ（橙色）膜时，Culet的外部的颜色变为蓝黑色。从拉曼光谱中，确认了蓝黑部分TMPD-TCNQ CT盐的形成。2。毛应力对PT（DPG）_2，BIS（Diphenylylyoximoximato）platinum（ii）PT（II）PT（DPG）_2 _2对应激敏感；它的颜色从红色变为绿色，变为黄色。我们已经通过拉曼光谱研究了剪切应力效应。 1431和1452 cm^<-1>处的C = N频段通过剪切变形显着移动。效应的估计是通过波数在波数中进行的。通过旋转10°施加剪切应力时，中心部分的应力从0.14 GPA增加到0.18 GPA，外部的应力从1.77 GPa增加到1.77 GPA到2.41 GPa。值得注意的是，剪切应力在外部的外部更强烈。3。毛应力对螺旋形肌吡喃6-硝基-BIPS的效果在外部的6-硝基-BIP的颜色在剪切变形下从橙色变为绿色。随着压力释放，它从绿色变为紫色。由于荧光强，无法在绿色部分获得旋转振动拉曼光谱，而光谱是在橙色和紫色部分测量的。该结果表明，剪切应力下的6-硝基-BIPS分子与环境压力下的分子不同。
