Use of vapochromic crystals to measure the concentration of a gaseous throughflow at the solid-fluid interface

Structural modifications to platinum(ii) pincer complexes resulting in changes in their vapochromic and solvatochromic properties

“…The complex can be incorporated as microcrystals into polymer membranes where the vapochromic behaviour remains the same, and the complex has been used to measure the concentration of a gaseous throughow at the solid-uid interface. 31 We now report an extension of this work to investigate the inuence of systematically changing the nature of the R group in the [Pt(N^C(R)^N)(CN)] complexes (Fig. 3) on the crystal structure and packing and how these changes alter the vapochromic and solvatochromic response to interactions with a range of volatile solvents and vapours.…”

“…46 Several attempts have been made at immobilising a vapochromic material into a polymer substrate in order to create "smart coatings" for chemical sensing applications. 31,47…”
