ground powders, at room temperature, can be accounted for by
the higher content of low emissive traps, rather than to different
crystal packing properties.
In conclusion, this study provides a new highly emissive
push–pull NLO chromophore, whose solid-state molecular
packing is driven towards J-type aggregation by means of aryl–

NLO properties of organic chromophores. Moreover, we have
shown that 1b possesses interesting mechanouorochromic
properties with emission dependent on the powder average
crystal sizes that can be tuned by grinding.
The mechanouorochromic properties of 1b as well as
fabrication of optoelectronic devices thereof are under current
investigation and will be reported elsewhere.
