The combination of π-conjugated fluorophores within a hybrid system gives rise to a triphenylamine-functionalized material [Zn(bpba)(NO3)] (1) (Hbpba = 4-(bis(4-(pyridin-4-yl)phenyl)amino)benzoic acid). Compound 1 features a 2D + 2D → 2D parallel polycatenation structure with 63-hcb net. Photophysical studies revealed that the title phase showed superior sensitivity towards p-nitroaniline (p-NA) with a low detection limit (down to ∼0.10 ppm). Specifically, following a new detection route, vapor-sensing experiments using a saturated ethanol solution of nitroaromatic isomers have been established for the first time. Highly sensitive and selective detection of p-NA by the proposed material with a rapid response time (t = 30 s, QE > 90.0%) as compared to that via the control isomers (t = 60s, QE < 6.0%) demonstrates an attractive feasible route and a promising luminescent sensor for nitroaromatic detection.
在杂化体系中，π-共轭荧光团的组合导致三苯胺功能化材料[Zn(bpba)(NO3)]（1）（Hbpba = 4-（双（4-（吡啶-4-基）苯基）氨基）苯甲酸）的形成。化合物 1 具有 2D + 2D→2D 平行聚轮烷结构，具有 63-hcb 网络。光物理研究表明，标题相表现出对 p-硝基苯胺（p-NA）的优异敏感性，检测限低（低至约 0.10 ppm）。具体而言，首次建立了使用硝基芳香异构体饱和乙醇溶液的新型检测途径的蒸气传感实验。与通过对照异构体（t = 60s，QE <6.0%）相比，所提出的材料对 p-NA 的高灵敏度和选择性检测具有快速响应时间（t = 30s，QE>90.0%），这证明了一种有吸引力的可行途径和一种有前途的用于硝基芳烃检测的发光传感器。
