Ammonia-Gated Guanyl Hydrazone Photoisomerization Enables Sequential Solid-State Optical Response in Hydrogen-Bonded Organic Frameworks.
Light-driven molecular switches enable precise and noninvasive regulation of molecular structure and function, and thus represent fundamental building blocks for stimuli-responsive photofunctional materials. However, translating molecular-level photoswitching into sequence-dependent macroscopic outputs in the solid sta...
