✅ 日本語まとめ：DSSCとスピロピラン
1. 非カルボン酸型スピロピランとCM-β-CDの共作用
- 使用材料：非カルボン酸型スピロピラン（1,3,3-trimethylindolino-β-naphthopyrylospiran）およびCM-β-CD。
- 成果：
- 光異性体（PMC）とCM-β-CDの包接錯体がTiO₂に吸着。
- IPCEは最大11.1％に上昇（570 nm照射時）、可視光照射によりIPCEは減少。
- CM-β-CDにより開放電圧やフィルファクターも向上。
2. 新規ハロゲン置換スピロピランの合成とDSSC応用
- 化合物：インドリン部位にClおよびBrを有する新規スピロピラン。
- 評価：
- NMR/IR/X線構造解析により構造を確認。
- UV照射前後でのDSSCの性能変化を評価。
3. SQ2およびSPNO2の共増感系DSSCの開発
- 材料：SQ2（感光色素）とSPNO2（光クロミック分子）を共増感。
- 結果：
- CD（特にγ-CD）はSQ2の凝集抑制によりηを向上（1.2%→1.5%）。
- UV照射により電極色が青→紫、可視光で紫→緑に変化。
- 効率向上は主にSPNO2からSQ2へのFRETによる。
✅ English Summary: DSSCs and Spiropyran
1. Noncarboxylated Spiropyran and CM-β-CD Inclusion Effect
- Materials: 1,3,3-trimethylindolino-β-naphthopyrylospiran and CM-β-CD.
- Findings:
- The photomerocyanine (PMC) form forms inclusion complexes with CM-β-CD and adsorbs on TiO₂.
- IPCE reached up to 11.1% at 570 nm due to inclusion effects; visible light decreased IPCE due to isomerization.
- CM-β-CD also improved fill factor and open-circuit voltage.
2. Novel Halogenated Spiropyrans for DSSC Applications
- Compounds: Newly synthesized indoline spiropyrans substituted with Cl and Br at position 5.
- Characterization:
- Structural analysis confirmed by NMR, IR, and X-ray crystallography.
- DSSC photoelectrochemical performance was evaluated before and after UV exposure.
3. Co-Sensitized DSSCs with SQ2 and SPNO2
- System: DSSCs co-sensitized with SQ2 dye and SPNO2 photochromic molecule.
- Results:
- γ-cyclodextrin suppressed aggregation of SQ2 and improved efficiency from 1.2% to 1.5%.
- Color of the electrode changed (blue → purple under UV, purple → green under visible light).
- FRET from SPNO2 to SQ2, rather than direct injection, enhanced photoelectric conversion.
- β-CD exhibited the highest FRET efficiency.
