Azobenzene chromophores are an ideal choice for material applications where functionality needs to be activated in a precise remote-controlled fashion. The azobenzene stimuli-response falls into two categories, either based on efficient trans-to-cis photoisomerization and a high cis yield enabling on-off type functions, or relying on a fast trans-cis-trans cycling creating motion in the material system. Herein, we show that using bisazochromophores instead of the more common monoazobenzene derivatives makes a difference in the performance of light-responsive azopolymers, more specifically in photo-orientation and all-optical surface patterning. Our findings point out that polymer-bisazobenzene complexes are an attractive alternative as high-performance photoreponsive materials and that although their properties are highly sensitive to the extent of conjugation in the system, they can be designed into relatively transparent films with high performance for all-optical patterning.

Paragraph 0066; 0073; 0106-0112, (2021/01/24)
The invention relates to the technical field of biology, in particular to a novel cannabinoid receptor light-operated ligand and a preparation method and application thereof. Disclosed is the cannabinoid receptor light-operated ligand or the isomer prodrug, the solvate and the pharmaceutically acceptable salt of the cannabinoid receptor light-operated ligand, wherein the structural formula of thecannabinoid receptor light-operated ligand is A-linker-B; A is a transmembrane domain ligand structure, and B is a light-operated element; Linker is a subunit which is linear and has no activity on acannabinoid receptor light-operated ligand. According to the invention, the cannabinoid receptor ligand is integrated with azobenzene through a proper connector, so that the ligand configuration is changed under an illumination condition, and the activation or inhibition state of the cannabinoid receptor is regulated and controlled.

Light-responsive molecular systems with multiple photoswitches in C3-symmetric designs have enormous application potential. The design part of such molecular systems is critical due to its influence in several properties associated with the photoswitches. In order to tune, and in the evaluation of the design–property relationship, we synthesized 18 tripodal systems with variations in the core, linkers, connectivity, and azo(hetero)arene photoswitches. Through extensive spectroscopic and computational studies, we envisaged the factors controlling near-quantitative photoisomerization in both the directions (bistability) and the thermal stability of the metastable states. Furthermore, we also evaluated the impact of designs in obtaining reversible photo-responsive sol-gel phase transitions, solvatochromism, photo- and thermochromism.
