Hydrogen-bonded organic framework-based host–guest ultralong organic phosphorescence (HOF-based HGUOP) materials with phosphorescent thermochromism property will become the next generation of intelligent optical functional materials in the future. Herein, three base-tuning HOF-based HGUOP co-crystal materials, Ma&Ct, Ma&Ae and Ma&Tm, are firstly created by respectively doping 1 mol% cytosine (Ct), adenine (Ae) and thymine (Tm) into melamine (Ma) host, these guests respectively lead to the blue shift, red shift and quenching of phosphorescence for Ma host. Notably, Ma&Ct performs an intensive “1 + 1 > 2” sensitized effect for photoluminescence (PL) and phosphorescence based on various synergetic interactions, the PL and phosphorescence quantum yields respectively get to 94.55 and 37.11%. The concentration and temperature-dependent photophysical performances of Ma&Ct, Ma&Ae and Ma&Tm are also recorded and analyzed. Relative mechanisms of phosphorescent thermochromism are firstly investigated deeply for Ma&Ct, Ma&Ae and Ma&Tm. In addition, phosphorescent thermochromism property of Ma&Ct and Ma&Ae have been well employed for information security and phosphorescent thermometer applications. This work not only proposes a simple preparation method of these new-type base-tuning HOF-based HGUOP co-crystal materials, but also explores the new internal phosphorescent thermochromism mechanism of these HOF-based HGUOP materials, which provides a typical case of HOF-based HGUOP materials using as smart flexible wearable phosphorescent thermometer.

用于信息安全和温度计的具有磷光热致变色的基调基于 HOF 的主客体超长有机磷光系统

具有磷光热致变色特性的基于氢键有机骨架的主客体超长有机磷光（HOF-based HGUOP）材料将成为未来的下一代智能光学功能材料。在此，首先通过将1 mol%胞嘧啶（Ct）、腺嘌呤（Ae）和胸腺嘧啶（Tm）分别掺杂到三聚氰胺（Ma）主体中，制备了三种调基HOF基HGUOP共晶材料Ma&Ct、Ma&Ae和Ma&Tm。 , 这些客体分别导致 Ma 主体的蓝移、红移和磷光猝灭。值得注意的是，Ma&Ct基于各种协同作用对光致发光（PL）和磷光表现出强烈的“1 + 1 > 2”敏化效应，PL和磷光量子产率分别达到94.55和37.11%。还记录和分析了 Ma&Ct、Ma&Ae 和 Ma&Tm 的浓度和温度相关的光物理性能。首先对Ma&Ct、Ma&Ae和Ma&Tm进行了深入研究磷光热致变色的相关机制。此外，Ma&Ct 和 Ma&Ae 的磷光热致变色特性已很好地用于信息安全和磷光温度计应用。本工作不仅提出了这些新型调基HOF基HGUOP共晶材料的简单制备方法，还探索了这些HOF基HGUOP材料新的内部磷光热致变色机理，为HOF基调光材料提供了一个典型案例。 -基HGUOP材料用作智能柔性可穿戴磷光温度计。Tm 也被记录和分析。首先对Ma&Ct、Ma&Ae和Ma&Tm进行了深入研究磷光热致变色的相关机制。此外，Ma&Ct 和 Ma&Ae 的磷光热致变色特性已很好地用于信息安全和磷光温度计应用。本工作不仅提出了这些新型调基HOF基HGUOP共晶材料的简单制备方法，还探索了这些HOF基HGUOP材料新的内部磷光热致变色机理，为HOF基调光材料提供了一个典型案例。 -基HGUOP材料用作智能柔性可穿戴磷光温度计。Tm 也被记录和分析。首先对Ma&Ct、Ma&Ae和Ma&Tm进行了深入研究磷光热致变色的相关机制。此外，Ma&Ct 和 Ma&Ae 的磷光热致变色特性已很好地用于信息安全和磷光温度计应用。本工作不仅提出了这些新型调基HOF基HGUOP共晶材料的简单制备方法，还探索了这些HOF基HGUOP材料新的内部磷光热致变色机理，为HOF基调光材料提供了一个典型案例。 -基HGUOP材料用作智能柔性可穿戴磷光温度计。Ma&Ct 和 Ma&Ae 的磷光热致变色特性已很好地用于信息安全和磷光温度计应用。本工作不仅提出了这些新型调基HOF基HGUOP共晶材料的简单制备方法，还探索了这些HOF基HGUOP材料新的内部磷光热致变色机理，为HOF基调光材料提供了一个典型案例。 -基HGUOP材料用作智能柔性可穿戴磷光温度计。Ma&Ct 和 Ma&Ae 的磷光热致变色特性已很好地用于信息安全和磷光温度计应用。本工作不仅提出了这些新型调基HOF基HGUOP共晶材料的简单制备方法，还探索了这些HOF基HGUOP材料新的内部磷光热致变色机理，为HOF基调光材料提供了一个典型案例。 -基HGUOP材料用作智能柔性可穿戴磷光温度计。
