酞菁类化合物具有优良的光电特性,选择适当的取代侧链可得到稳定的LB成膜材料,可望在微电子器件等方面获得重要的应用.本工作观测了四-4-(2,4-二特戊基苯氧基)酞菁铜(CuPc(Dt-PP)_4)在银岛膜上的LB单分子层的表面增强共振拉曼散射(SERRS)光谱。比较其固体粉末的共振拉曼散射(RRS)光谱,讨论了酞菁铜分子大环在载片表面的取向及其可能的原因。1 实验CuPc(Dt-PP)_4样品由陈文启等合成,经元素分析、IR、NMR、色谱等研究确认其结构如图1所示.银岛膜用真空蒸镀法制备在玻璃载片上。用同时蒸镀在铜网上的银膜的透射电
Phthalocyanines have excellent optoelectronic properties and can be used to obtain stable LB film-forming materials by selecting the appropriate side-chain substitutions, which are expected to be of great importance in the field of microelectronic devices etc. In this work, Surface Enhanced Resonance Raman Scattering (SERRS) Spectra of LB Monolayers on Silver Island Films by CuPc (Dt-PP) _4. Resonance Raman scattering (RRS) spectra of solid powders were compared. The orientation of copper phthalocyanine macromolecule on the surface of slides and the possible reasons were discussed. 1 The experimental CuPc (Dt-PP) _4 samples were synthesized by Chen et al. The structure of CuPc (Dt-PP) _4 was confirmed by elemental analysis, IR, NMR and chromatogram as shown in Fig. 1. The silver island membrane was prepared on a glass slide by vacuum evaporation. Transmission of silver film deposited on copper foil by simultaneous vapor deposition
