Naphthopyran molecular switches undergo a ring-opening reaction upon external
stimulation to generate intensely colored merocyanine dyes. Their unique modularity and …

Polymer mechanochemistry uses mechanical forces to break and manipulate chemical
bonds, driving a functional response in the material of choice, thus making it an ideal …

Many living organisms have the superb structure‐editing capacity for better adaptation in
dynamic environments over the course of their life cycle. However, it's still challenging to …

Optical force probes that can release force‐dependent and visualized signals with minimal
changes in the polymer main chains under mechanical load are highly sought after but …

We report a versatile mechanophore exhibiting a vividly detectable, light‐regulable
multicolor mechanochromism. Such optical features rely on the synergistic coupling of …

Stimulus-responsive gating of chemical reactions is of considerable practical and
conceptual interest. For example, photocleavable protective groups and gating …

Molecular photoswitches are extensively used as molecular machines because of the small
structures, simple motions, and advantages of light including high spatiotemporal resolution …

Mechanophores (mechanosensitive molecules) have been instrumental in the development
of various force-controlled release systems. However, the release of functional organic …

In contrast to common angular naphthopyrans that exhibit strong photochromic and
mechanochromic behavior, constitutionally isomeric linear naphthopyrans are typically not …

Xanthene-based functional dyes have diverse applications in life science and materials
science. A current challenge is to develop new dyes with suitable physicochemical …
