title: Achieving red/near-infrared mechanoresponsive luminescence turn-on: mechanically disturbed metastable nanostructures in organic solids.
abstract: Two slightly twisted A-π-D-π-A molecules were prepared to demonstrate that the red/near-infrared mechanoresponsive luminescence turn-on behaviors could be realized through mechanically disturbing their weakly/non-emissive metastable nanostructures, giving emissive amorphous aggregates with λem= 620 nm, ΦF= 12% (h-DIPT) and λem= 700 nm, ΦF= 10% (DIPT), respectively.
