Example Sentences

By attaching bulky, stationary molecules to the phenylene rings, researchers induced a "clutch stack" arrangement, where adjacent triaryltriazine molecules are rotated 60° from each other, rather than stacking in the same orientation.

From Science Daily • Jan. 19, 2024

Researchers utilized a gear-shaped molecule called triaryltriazine, which has a center triazine ring with three phenylene rings attached to it -- which act like the teeth of a gear.

From Science Daily • Jan. 19, 2024

This change in motion was attributed to a phase transition in the crystal that created more space between adjacent molecules, giving the phenylene rings more room to rotate.

From Science Daily • Jan. 19, 2024

The clutch stack arrangement of the triaryltriazine molecules enabled adjacent molecules to hook on to each other as the phenylene rings rotated, much like interlocking gears.
