Scheme 1From: Exploring the Intrinsic Piezofluorochromic Mechanism of TPE-An by STS Technique a Geometrical configuration of TPE-An molecule. b The conformer of TPE-An molecule with the lowest energy by simulation. This molecule has a highly twisted conformation. The bond angle (A-B) and (B-C) is 58°, and that of (B-D) is 80°. And the bond angle of (B-E) and (C-D) is equal to 75°Back to article page
