“…Hitherto, most of CHPMs are supported by photodeformable ligands with examples of diarylethylene‐/azo‐derivatives [15–18] or photoresponsive ligands like pyridinium‐derivatives [19–30] . Besides the CHPMs based on photodeformable or photoresponsive ligands, [15–40] the conjugated N ‐heterocycle moieties as potential electron acceptors (EAs) are also desirable units for yielding CHPMs [41–50] . The assembly of various EAs moieties, electron donors (EDs) species, and metal ions generates assorted CHPMs driven by photoinduced electron‐transfer (ET) between EDs and EAs, [41–55] and the resulting CHPMs feature additional fascinating photoresponsive functionality like photomagnetism, photocurrent, sensor for X‐ray, etc [41–55] …”

As promising photoresponsive materials and potential smart materials, hybrid photochromic materials (HPMs), especially for crystalline HPMs (CHPMs), have been broadly explored for their potential in inheriting the merits of each constituents, and intriguing photomodulated functionality. Hitherto, the photoresponsive functionality in explored CHPMs mainly concentrate on dyad combination. By contrast, triple or quadruple photoresponsive properties are very rare because of the limited compatibility of multiple photoresponsive functionality in a single system. In this work, the electron-transfer (ET) and crystal engineering strategies were utilized to predesign CHPMs with multiple photoresponsive properties via the collaboration of paramagnetic metal ion (Dy 3 + ), electron-donor (ED) ligand (benzene-1,2,3-tricarboxylic acid, H 3 BTA) and electron-acceptor (EA) ligand (1,10-phenanthroline, phen). The resulting complex [Dy(BTA)(phen) 2 ]•2H 2 O (1) shows hybrid chain with the intrachain Dy 3 + ions bridged and chelated by tricarboxylate and phen ligands, respectively. After photostimuli, the ET between tricarboxylate and phen results in photogenerated radicals and the resultant quadruple photoresponsive properties. Considering the abundant resources of paramagnetic metal ions, ED-and EA-ligands, this work provides a general method to construct CHPMs with multiple photoresponsive performances via the collaboration of each unit under the guidance of ET and crystal engineering strategies.

The fusion of bipyridinium and their derivatives and metal ions to construct functional coordination compounds has attracted tremendous attention recently. Due to their advantages in easy modification, electron-deficient characteristic and photoelectrochemical activity, such compounds as smart stimuli-responsive materials, show a wide variety of intriguing applications including chromic response, switching, adsorption, sensing, magnet, and catalysis, etc. Based on the electron transfer (ET), charge transfer (CT) and their synergism, this review summarizes the latest research progress of our group in regulating the structure and stimuli-responsive function of pyridinium-based complexes in recent years. Finally, we provide further prospects for the development of pyridinium-based complexes in the field of multi-stimuli-responsive materials in the future.

“…In recent literature, the research on X‐ray‐induced photochromism for personal X‐ray visualization is concentrated on metal–organic systems. [ 11–15 ] On the other hand, hackmanite's ability to color upon X‐ray exposure has been known at least from the 1950s, [ 6 ] but its suitability for X‐ray detection has not been studied previously. Neither are the mechanisms by which the color is created and bleached known.…”

Hackmanites, a variety of sodalite with the general formula Na8Al6Si6O24(Cl,S)2, are a family of nature‐based smart materials having the ability for reversible photochromism upon UV or X‐ray exposure. Being nontoxic, cheap, and durable, hackmanite would be an optimal material for the visual detection of the presence of X‐rays in simple portable systems. However, its X‐ray‐induced coloring abilities are so far known only qualitatively. In this work, a combination of experimental and computational methods is used to reveal the mechanism of X‐ray‐induced color changing in these materials. Finally, their use is demonstrated both in color intensity‐based X‐ray dosimetry and photochromic X‐ray imaging.
