Fluorescent 2D metal–organic framework nanosheets (MONs): design, synthesis and sensing of explosive nitroaromatic compounds (NACs)

2D metal–organic nanosheets (MONs) constructed from 6-connecting hexaacid based on electron-rich 1,3,5-triphenylbenzene core and In(iii) salt permit detection of nitroaromatic compounds, e.g. TNT, in ppm levels.
