Abstract Molecular photoswitches can undergo isomerization under light exposure, making them uniquely attractive for high spatiotemporal resolution remote control of biological functions. Visible and near‐infrared (NIR) light, with their low energy consumption, safety, strong tissue penetration, are particularly suitable applications. Therefore, developing visible‐ NIR light‐driven molecular use is great significance. This review introduces the most common presents state‐of‐art applications in bioimaging, biosensing, drug delivery, photocontrolled cancer phototherapy, photopharmacology. The opportunities challenges future development outlined.

Photothermal reactions, involving both photochemical and thermal reaction steps, are the most abundant sequences in photochemistry. The derivation of their rate laws is standardized, but integration these has not yet been achieved. Indeed, field still lacks integrated for description reactions’ behavior and/or identification order. This made difficult a comprehensive account photokinetics photothermal which created gap knowledge. addressed present paper by introducing an unprecedented general model equation capable mapping out kinetic traces such reactions when exposed to light or dark. law also applies reactive medium either monochromatic polychromatic irradiation. validity was established against simulated data obtained fourth-order Runge–Kutta method. It then used describe quantify several situations as effects initial concentration, spectator molecules, incident radiation intensity, impact latter on photonic yield. facilitated elucidation method determine intrinsic parameters (quantum yields absorptivities species) any mechanism whose number species known. contributes rationalizing along same guidelines adopted chemical kinetics.

Abstract Diarylethenes are a well‐studied and optimized class of photoswitches with wide range applications, including data storage, smart materials, or photocontrolled catalysis biological processes. Most recently, aza‐diarylethenes have been developed in which carbon‐carbon bond connections replaced by carbon‐nitrogen connections. This structural elaboration opens up an entire new structure property space expanding the versatility applicability diarylethenes. In this work, we present second generation zwitterionic aza‐diarylethenes, finally allows for fully reversible photoswitching precise control over all three switching states.

Abstract Molecular photoswitches produce light‐controlled changes at the nanometer scale and can therefore be used to alter states behavior of materials in a truly bottom‐up fashion. Here an escalating photonic complexity material property control with light is shown using recently developed aza‐diarylethene combination hemiindigo (HI) photoswitches. First, as photoswitch polystyrene (PS) reversibly inscribe relief‐type 3D structures into PS. Second, further photoinitiator for light‐induced polymerization methyl acrylate (MA), demonstrating first time chemical reactivity its zwitterionic switching state. Third, HIs are implemented polymerized MA, generating photochromic polymers. At fourth level, binary mixture allows synergize aza‐diarylethene‐induced photopolymerization localized photochromism simultaneously entrapped functional HI. With such multilevel response, utility this particular applications advanced demonstrated.
