Orderly Ultrathin Films Based on Perylene/Poly(N-vinyl carbazole) Assembled with Layered Double Hydroxide Nanosheets: 2D Fluorescence Resonance Energy Transfer and Reversible Fluorescence Response for Volatile Organic Compounds

Orderly Ultrathin Films Based on Perylene/Poly(N-vinyl carbazole) Assembled with Layered Double Hydroxide Nanosheets: 2D Fluorescence Resonance Energy Transfer and Reversible Fluorescence Response for Volatile Organic Compounds

Neutral poly(N‐vinyl carbazole) (PVK) and perylene are coassembled within the interlayers of layered double hydroxide (LDH) nanosheets to form (perylene@PVK/LDH)n ultrathin films by the hydrogen‐bond layer‐by‐layer assembly method. An efficient 2D fluorescence resonance energy transfer (FRET) proces...

Zusammenfassung:Neutral poly(N‐vinyl carbazole) (PVK) and perylene are coassembled within the interlayers of layered double hydroxide (LDH) nanosheets to form (perylene@PVK/LDH)n ultrathin films by the hydrogen‐bond layer‐by‐layer assembly method. An efficient 2D fluorescence resonance energy transfer (FRET) process from PVK to perylene is demonstrated, and this FRET process can be inhibited/recovered reversibly by the adsorption/desorption of common volatile organic compounds (VOCs).
