Two isomers of mm-TPE(PI)2 and pp-TPE(PI)2, constructed by the two same aromatic blocks of tetraphenylethene and phenanthro[9,10-d]imidazole, exhibit totally different mechanoluminescence, as a result of the ignorable different linkage positions on the tetraphenylethene moiety. Detailed analysis and theoretical calculations demonstrate the structure-packing-property relationship of organic mechanoluminescent luminogens, with the emphasis on the important role of molecular packing in the solid state.

The synthesis of a new tetraborylethylene (TBE) is reported, and its application in the preparation of [4+0]-tetraarylethenes (TAEs) is elucidated. TAEs have widespread applications in material science and supramolecular chemistry due to their aggregation-induced emission (AIE) properties. The divergent and stereoselective synthesis of [3+1]-, [2+2]-, and [2+1+1]-TAEs via multiple couplings of vinylboronates with aryl bromides is demonstrated. These couplings feature a broad substrate scope and excellent functional group compatibility due to mild reaction conditions. Facile access to various tetraarylethenes is provided. This strategy represents an important complement to the conventional methods employed for the synthesis of TAEs, and would be a valuable tool for synthesizing TAE-based molecules useful in functional materials, biological imaging and chemical sensing.
