Dye sensitizers are entities designed primarily to serve the function of harvesting light photons in the functional wavelength, which is centered on charge transfer mechanisms. A metal-free dye sensitizer (J) based on the naphthyl-thiazole groups was synthesized via a one-step reaction mechanism and characterized using spectroscopic methods of UV-vis, 1H NMR and fluorescence. The applications of J were investigated based on its charge transfer mechanisms of photoinduced electron transfer (PET) and excited-state intermolecular proton transfer (ESIPT) mechanisms. Subsequently, J displayed several charge transfer-based properties complimentary to dye sensitizers, chemosensing and molecular logic functions. The properties were investigated and studied primarily in acetonitrile (CH3CN), as a polar solvent of choice. Optical properties of J were investigated through solvatochromism, aided by theoretical recreation, while chemosensing properties were investigated, thereby in the process establishing that J is a ditopic probe which could selectively discriminate CN-, F- and AcO- as well as Fe3+ in CH3CN, among other ions. In addition, the reversibility and reproducibility studies substantiated that J exhibits molecular logic operation properties, based on complimentary IMP/INH logic functions. Thus, J can be utilized as a colorimetric molecular switch modulated by CN-/Hg2+.

潜在的基于萘基噻唑的有机染料和具有分子逻辑功能的CN-和Fe3 +的对位发色探针

染料敏化剂是主要设计用于实体收集功能波长的光子的功能的实体，该波长以电荷转移机制为中心。通过一步反应机理合成了基于萘基-噻唑基的无金属染料敏化剂（J），并使用紫外可见光谱，1H NMR和荧光光谱法对其进行了表征。基于光诱导电子转移（PET）和激发态分子间质子转移（ESIPT）的电荷转移机理研究了J的应用。随后，J显示了几种基于电荷转移的性质，这些性质与染料敏化剂，化学传感和分子逻辑功能互补。主要在乙腈（CH3CN）（作为选择的极性溶剂）中对性能进行了研究。通过溶剂变色法研究了J的光学性质，并通过理论研究对其进行了研究，同时研究了化学传感性质，从而在此过程中确定J为对位探针，可以选择性区分CH3CN中的CN-，F-和AcO-以及Fe3 +，在其他离子中。此外，可逆性和可重复性研究证实，J具有互补的IMP / INH逻辑功能，因此具有分子逻辑操作特性。因此，J可以用作由CN- / Hg2 +调制的比色分子开关。可逆性和可重复性研究证实，J具有互补的IMP / INH逻辑功能，因此具有分子逻辑操作特性。因此，J可以用作由CN- / Hg2 +调制的比色分子开关。可逆性和可重复性研究证实，J具有互补的IMP / INH逻辑功能，因此具有分子逻辑操作特性。因此，J可以用作由CN- / Hg2 +调制的比色分子开关。
