An elastic orange-red film (PDMS-PtL1) has been prepared by grafting formyl-containing Pt(II) complex Pt ((NCN)-C-boolean AND-N-boolean AND)Cl ((NCN)-C-boolean AND-N-boolean AND=1,3-dipyridyl benzene) onto polydimethylsiloxane (PDMS) backbone. The film was highly stretchable (up to 1500% strain) and shows room-temperature self-healing property. Interestingly, stretch-induced luminescent change of the film was observed, where an emission tentatively originating from (3)pi-pi* of separated platinum moieties was detected after stretching. Luminescence quenching is avoided in this elastic film, and the switch of emission state can be realized by changing external forces. CCDC: 1966072, L2.
