Abstract The bis(β-diimino-tetracyano-pyrrolizinido)-Cu(II) complex (CuL2) has been incorporated in polystyrene (0.28% w/w), by evaporating tetrahydrofuran solutions either at room temperature (a) or at 100°C (b). From IR and UV-vis measurements and optical microscopy on the resulting films (a orb, thickness 50 μm) it is concluded that CuL2 is present as a concentrated (C≈10−1 M) THF solution ina and as small solid particles (diameter 〈1 μm) inb. The difference in colour of the films (dark bluea, light blueb), due to the different physical state of CuL2 in the matrix, is expected, and has been preliminarily shown using similar films based on NiL2, to be useful for sensing organic vapours in the atmosphere.
