High-efficiency Luminescence Detection of Nitroaromatics by Platinum（Ⅱ） Complex with Aggregation-induced Emission
Bibliographic record
Abstract
合成了一例三苯胺基团修饰的铂（Ⅱ）配合物PtppyTPA，并详细地表征了其结构及光物理性质。研究表明，三苯胺基团可有效激活PtppyTPA的聚集诱导发光（AIE）性能，使其在含水量为50%的乙腈中呈现显著的发光增强。以AIE活性的PtppyTPA为发光探针实现了对4种硝基芳烃包括硝苯地平（Nifedipine，NFD）、5⁃氯⁃2⁃硝基三氟甲苯（5⁃chloro⁃2⁃nitrotrifluorotoluene，ClNTFT）、4⁃溴⁃1⁃氟⁃2⁃硝基苯（4⁃bromo⁃1⁃fluoro⁃2⁃nitrobenzene，BrFNBz）及3⁃硝基三氟甲苯（3⁃nitrotrifluorotoluene， NTFT）的发光检测，利用Stern⁃Volmer方程拟合检测数据并计算了检测效率及检测限。PtppyTPA对上述硝基芳烃的检测效率分别为11.12，0.27，0.25，0.21 L/mmol；检测限分别为7.1，291.0，314.3，374.2 μmol/L。PtppyTPA对NFD具有最高的检测效率和最低的检测限。前线轨道能级及光谱交叠实验表明，PtppyTPA对NFD、ClNTFT、BrFNBz及NTFT的检测机理为电子转移。

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
