For controlling the surface properties by depositing molecules on the material surface, the selection of the functional groups of the stacked molecules is crucial. By introducing anthracenes in the molecular layer, which promote photodimerization and thermal/cleavage on photoirradiation or heating, it is possible to form a stimuli-responsive surface that enables changes in the molecular layer composition. In this study, we improve the fabrication process of the stimulus-responsive molecular layer with anthracene in order to facilitate the design of molecular layers according to the desired purpose. This is achieved by employing acid-base interactions for forming the molecular layers, with different functions for each layer. Thermal/photocleavage reactions of anthracene dimers are induced in the stacked molecular layer. Multilayers stacked with amine molecules exhibit different behavior on the cleavage reaction and the contact angle varies, depending on the type of molecules. The wettability on the surface covered with the molecular layer changes in response to the stimulation, proving the successful fabrication of a stimuli-responsive surface. The designed thermo- and photoresponsive molecular layer can potentially expand the scope of practical application as a control system for surface conditions.

为了通过在材料表面沉积分子来控制表面特性，堆叠分子的官能团的选择至关重要。通过在分子层中引入蒽，在光照射或加热时促进光二聚化和热/裂解，可以形成刺激响应表面，使分子层组成发生变化。在这项研究中，我们用蒽改进了刺激响应分子层的制造工艺，以促进根据预期目的设计分子层。这是通过使用酸碱相互作用来形成分子层来实现的，每层具有不同的功能。在堆叠的分子层中诱导蒽二聚体的热/光裂解反应。与胺分子堆叠的多层膜在裂解反应中表现出不同的行为，并且接触角因分子类型而异。被分子层覆盖的表面的润湿性随着刺激而变化，证明了刺激响应表面的成功制造。设计的热响应和光响应分子层可以潜在地扩展作为表面条件控制系统的实际应用范围。
