在光学显微镜和原子力显微镜下观察到，在亲水性玻璃基片上区域浇铸的苝-3，4，9，10-四正戊酯液晶形成了特征性的带状结构。偏振拉曼散射光谱揭示了所获得的结构内部的分子的各向异性排列的存在。此外，吸收光谱和荧光光谱证实了分子聚集在带状结构。研究表明，带状结构是由分子柱在玻璃基片上沿边缘排列形成的。分子的这种结构可以用光谱方法证实。从有机电子学的角度来看，这些结构可能是有趣的。
Liquid-crystalline perylene-3,4,9,10-tetra-(n-pentylester) zone-casted on hydrophilic glass substrates forms characteristic belt-like structures which are observed under optical microscope and atomic force microscope. Polarised Raman scattering spectra reveal the presence of anisotropic alignment of the molecules inside the obtained structures. Moreover, the absorption and fluorescence spectra confirm molecular aggregation in the belt-like structures. The research shows, that the belt-like structures are created by columns of molecules with the edge-on alignment on the glass substrate. Such organisation of the molecules is confirmed by spectroscopic methods. These structures can be interesting from the point of view of organic electronics.
