Organic/inorganic hybrid materials - like zeolites + dyes - are currently used in strategic areas, from sustainable energy technologies to biomedical sciences. In these systems, photoactive molecules are organized in one-dimensional nanostructures inside the zeolite channels. In this paper we present the results of a study aimed to the synthesis and the structural and spectroscopic characterization of azobenzene/AlPO₄-5 hybrid composites, performed by a multi-technique approach based on material synthesis, thermal gravimetric analysis, synchrotron X-ray powder diffraction, UV-VIS and IR spectroscopies. The results indicate that azobenzene molecules are hosted in the 12-membered ring channel of AFI framework and the maximum loading is 0.9 molecules per unit cell. The combination of spectroscopic and diffractometric methods point out that, being AlPO₄-5 starting material affected by Brönsted acidity, a consistent portion of the azobenzene molecules is protonated and interact with the framework oxygen atoms.

从可持续能源技术到生物医学，有机/无机杂化材料（如沸石+染料）目前用于战略领域。在这些系统中，光敏分子在沸石通道内以一维纳米结构组织。在本文中，我们介绍了针对偶氮苯/ AlPO ₄的合成以及结构和光谱表征的研究结果。-5杂化复合材料，通过基于材料合成，热重分析，同步加速器X射线粉末衍射，UV-VIS和IR光谱的多种技术方法完成。结果表明，偶氮苯分子位于AFI框架的12元环通道中，每单位细胞的最大载量为0.9个分子。光谱和衍射法的结合指出，作为受布朗斯台德酸度影响的AlPO ₄ -5起始材料，偶氮苯分子的恒定部分被质子化并与骨架氧原子相互作用。
