ATR-IR spectra for a 1,2-dithiolane derivative 1a (red) as compared with functionalized MoS2-based nanohybrids 2a (black) and 2c (gray), and b 1,2-dithiolane derivative 1b (red) and MoS2-pyrene 2b (black). Raman spectra for c exfoliated MoS2 (gray) as compared with functionalized MoS2-pyrene 2b (black), obtained upon 633 nm excitation. Thermographs for d exfoliated MoS2 (gray) as compared with that due to functionalized MoS2-pyrene 2b (black), obtained under nitrogen atmosphere
