Synthesis and Characterization of Calix[4]resorcinarene Bearing Azobenzene Moieties as Novel Photofunctional Amorphous Molecule

抄録

Calix[4]resorcinarene bearing azobenzene moieties (CADR) was prepared by etherification of calix[4]resorcinarene (C4RA) with Disperse Red-1 derivatives (_DR-1s). The photofunctional properties were evaluated by measuring second harmonic generation (SHG), electro-optic (E-O) coefficient and surface relief grating (SRG). The second harmonic coefficient (d₃₃) of CADR and the electro-optic coefficient (γ₃₃) at the wavelength of 1064nm were 97.06×10^-9 [esu] and 18.43 [pm/V] without corona poling treatment. The diffraction image by SRG was successfully recorded and the hologram of 1μm width was also obtained.
