Flapping Molecules and the Skeletal Motion for New Technologies

Abstract

Flapping molecule (FLAP) is an emergent class of functional system that shows ultrafast conformational planarization in the singlet excited state, multifold columnar stacking in a condensed phase, and compulsory planarization in stretched polymers. Here, representative applications of FLAP are introduced such as highly sensitive viscosity probe, molecular adhesive with photoinduced melting function, and ratiometric fluorescent force probe.
