Abstract

A multifunctional crystalline gallophosphate, |C10N2H9|[Ga(PO4)(H2PO4)] (NEU26), was synthesized via an ionothermal strategy employing tetrabutylammonium phosphate as a versatile ionic liquid that simultaneously functions as the reaction medium and phosphorus source, while exerting solvent-mediated microenvironment modulation during crystallization. This approach demonstrates, for the first time, the feasibility of constructing photochromic gallophosphate open-frameworks using a nonphotoactive organic template, 4,4'-bipyridine, in combination with a multifunctional ionic liquid to streamline the synthesis. The one-dimensional open-framework of NEU26 exhibits distinct and reversible UV-induced photochromism, attributed to photoinduced electron transfer from inorganic anionic chains to monoprotonated Hbpy+ species, generating tunable colored Hbpy· radicals. Leveraging both its photochromic behavior and intrinsic photoluminescence, NEU26 integrates multiple functionalities, including light-gated fluorescence modulation (on/off ratio of 13:1), UV dosimetry, erasable inkless printing, and anticounterfeiting encryption. This study highlights the synthetic utility of multifunctional ionic liquids in the targeted construction of advanced hybrid frameworks and offers new insights into the rational design of responsive, multifunctional materials.

离子液体介导的离子热合成多功能光致变色没食子磷酸盐。

以四丁基磷酸铵为多用途离子液体，在结晶过程中发挥溶剂介导的微环境调节作用，通过离子热策略合成了一种多功能聚磷酸结晶|C10N2H9|[Ga(PO4)(H2PO4)] （NEU26）。该方法首次证明了使用非光活性有机模板4,4'-联吡啶与多功能离子液体结合构建光致变色没食子磷酸盐开放框架的可行性，从而简化了合成过程。NEU26的一维开放框架表现出明显的可逆紫外诱导光致变色，这是由于光诱导电子从无机阴离子链转移到单质子化的Hbpy+基团，产生可调谐的有色Hbpy·自由基。利用其光致变色行为和固有的光致发光，NEU26集成了多种功能，包括光门控荧光调制（开/关比为13:1）、紫外线剂量测定、可擦除无墨水打印和防伪加密。这项研究突出了多功能离子液体在先进混合框架的目标构建中的合成效用，并为响应性多功能材料的合理设计提供了新的见解。
