Porphyrins are tetrapyrrolic macrocycles with a fascinating and multifarious variegation of properties of essential significance in up-to-date and leading technologies. From a different point of view, the Langmuir-Blodgett technique allows the immobilisation of films with an accurate regulation of molecular organisation and thickness. As a logical upshot, this manuscript concerns a substantial object of consideration in contemporary research, the utilisation of Langmuir-Blodgett multilayers of porphyrins in sensing elements for the detection of analytes in different matrices. Investigations on the morphological, optical, structural and surface characteristics of these films are remarkably related to the significant properties of sensors with the ultimate goal of rationalising the innermost intercourses between the sensing behaviour and the peculiarities and molecular organisation brought about by the deposition method. The integration of the typical electrical and optical characteristics of porphyrins with the potentialities of the Langmuir-Blodgett multilayer has originated not only encouraging projects but has afforded also certainties on the accomplishment of operative chemical sensors.
卟啉是四吡咯大环化合物，具有迷人的、多样化的性质，对现代和领先技术具有至关重要的意义。从另一个角度来看，Langmuir-Blodgett 技术允许通过精确控制分子组织和厚度来固定薄膜。因此，本文涉及到当代研究中的一个重要课题，即利用 Langmuir-Blodgett 卟啉多层膜作为不同基质中分析物检测的传感元件。对这些薄膜的形态、光学、结构和表面特性的研究与传感器的重要性质密切相关，其最终目标是使传感行为与由沉积方法引起的特性和分子组织之间的内在相互作用合理化。卟啉的典型电学和光学特性与 Langmuir-Blodgett 多层膜的潜力相结合，不仅产生了令人鼓舞的项目，而且还为实现有效的化学传感器提供了一定的保证。
