Structure, photoluminescence characteristics, and chirality of Cu2Au2(R-BTT)4 and Cu2Au2(S-BTT)4. (a) Molecular structure and ball–stick model of Cu2Au2(R/S-BTT)4. (b) Photographs under indoor light and UV light and (c) photoluminescence quantum efficiency spectra under an excitation at 365 nm of Cu2Au2(R/S-BTT)4 in solution and film states. (d–f) PL characteristic variation as Cu2Au2(R-BTT)4 and Cu2Au2(S-BTT)4 transfer from solutions to films. (d) Normalized PL emission (solid line) and normalized PL excitation (PLE, short dot) spectra. The PL and PLE spectra were excited and recorded at 365 and 540 nm, respectively. (e) PL intensity evolution curves under a constant excitation at 365 nm. The PL intensity was recorded at 540 nm. (f) TRPL decay curves. (g) CD spectra, (h) CPPL spectra, and (i) gPL versus wavelength curves of Cu2Au2(R/S-BTT)4 films.
