Figure 6

(a) Fluorescence spectra of metallacycle 2 and ligand 4-based, silica-gel plate supported films, where the inset is a picture of ligand 4 (left) and metallacycle 2 (right) deposited on a silica plate surface taken under UV light (365 nm); (b) Response traces of the metallacycle 2-based film to the presence of saturated vapors of the VSOMs under study and water; (c) Fluorescence emission spectra of metallacycle 2-based film with and without aniline vapor, where the inset is a picture of the film taken before and after treatment with aniline vapor under UV light (365 nm); (d) Fluorescence emission spectra of the film before and after treatment with Et2NH vapor, where the inset is a picture of the metallacycle 2-based film taken before and after treatment with Et2NH vapor under UV light (365 nm). Note: Presence of green spots in the inserted picture (d) is a result of fast response and fast recovery with treatment of Et2NH vapor.
