Tunable photosalient behaviours within coordination polymers via functional molecular prearrangements.

Four Cd(II)/diene coordination polymers (CPs) with similar 1D chain motifs exhibit different photosalient (PS) behaviours in response to UV light. The [2+2] photoreaction between the C＝C groups within these CPs results in diverse PS behaviours of their crystals with different C＝C pair arrangements. The interesting PS behaviours of these CPs can be applied in design and fabrication of advanced photoactuating materials. [ABSTRACT FROM AUTHOR]
