“…Donor–acceptor (D–A) hybrid crystals are an emerging kind of crystalline hybrid materials composed of semiconductive inorganic donors and organic acceptors and have drawn considerable attention because of their potential applications in optoelectronic devices. , Among them, the HOMO of both donors and acceptors can be excited to LUMO upon light irradiation and leads to the photoinduced electron transfer (PIET), which generates photochromism. , Moreover, photochromic properties, which are mainly dependent on the inorganic components and the molecular packing modes, have been extensively investigated. − Indeed, several groups, including ours, have reported an array of such D–A hybrid crystals with various inorganic components, like polyoxometalate anions, alkaline-earth metal oxide chains, and metal halides, as well as different packing patterns (with or without coordinated metal cations).…”

Donor−acceptor (D−A) hybrid crystals are an emerging kind of crystalline hybrid material composed of semiconductive inorganic donors and organic acceptors. Except for the intrinsic photochromism, recently we have reported that the anion-π polyoxometalate (POM)/naphthalenediimide (NDI) hybrid crystals could produce an interesting room temperature phosphorescence (RTP) quantum yield up to 7.2%. Herein, we extended into coresubstituted NDIs and anticipated the regulation of their photochromic and RTP properties. Thus, two hybrid crystals, namely (H 4 BDMPy-Br 2 NDI)•(NMP) 4 •(HPW 12 O 40 ) (1) and (H 4 BDMPy-I 2 NDI)• (HPW 12 O 40 ) (2) (H 2 BDMPy-Br 2 NDI: N,N′-bis(3,5-dimethylpyrazolyl)-2,6-dibromo-1,4,5,8-naphthalenediimide and H 2 BDMPy-I 2 NDI: N,N′-bis(3,5-dimethylpyrazolyl)-2,6-diiodide-1,4,5,8-naphthalenediimide), have been synthesized from phosphotungstic anions (PW 12 O 40 3− ) and Br or I core-substituted NDIs. Compared to the coreunsubstituted analogues (H 4 BDMPy-NDI)•(NMP) 4 •(HPW 12 O 40 ) ( 3), 2 with photosensitive iodine substituents is more sensitive to light, which can become discolored under natural light. As a result of the heavy-atom effect, hybrid 1 exhibits remarkable RTP with the quantum yield up to 10.2% and a lifetime of 1.14 ms.

“…Photochromism refers to the reversible color-change phenomena induced by the external UV or visible-light stimuli. − Photochromic materials, especially crystalline photochromic materials, have attracted tremendous scientific attentions owing to their promising applications in information storages, photoswitchable conductances, erasable inks, and smart windows. − In recent years, considerable efforts have been dedicated to developing novel multicomponent inorganic–organic photochromic hybrids with enhanced photoresponsibility and exploring photoresponsive systems with various switchable functions, such as luminescent, conductive, and magnetic properties. − Meanwhile, various factors including packing types, metal cations, anions, and organic ligands on photochromic performances have been carefully studied. − However, the hybrid isomers with the same components but different photochromic behaviors have remained rarely explored. , To fill this gap, it is of particular significance to design and synthesize such supramolecular isomers and further study their structure–property relationships.…”

Supramolecular isomerism in coordination compounds, an ideal platform for understanding the self-assembly and structure–property relationships, has received extensive research interest in the past decades. In this context, we have synthesized five multifunctional three component viologen-based 3d-4f hetereobimetallic supramolecular isomers with tunable properties depending on the synthetic conditions, especially stoichiometric amounts of the components, namely, 2D network {[Tb (BCEbpy) (H2O)4]·[CoIII(CN)6]}·4H2O (1), 1D coordination chain [Tb0.5(BCEbpy)0.5 (H2O)3]·[CoIII(CN)6]0.5 (2), 3D framework {[Tb(BCEbpy)(H2O)4][CoIII(CN)6)]}·H2O (3), 2D network {[Tb(BCEbpy)(H2O)4][CoIII(CN)6)]}·2H2O (4), and {[Tb0.5(BCEbpy)0.5 (H2O)2][CoIII(CN)6]0.5}·H2O (5) via a self-assembly method. Single-crystal X-ray analyses reveal that the binding mode of [CoIII(CN)6]3– has a dramatic influence on the final structures of the heterometallic frameworks and further results in their distinct photochromic behaviors upon irradiation. Further careful inspection of the structures of these complexes indicates that the different photochromic behaviors could be mainly attributed to their different packing modes and electron-accepting abilities of the bipyridinium unit. In addition, these compounds show multicolored switchable photoluminescence via selective excitation of the green emissive Tb3+, blue luminescent conjugated ligand BCEbpy, and red luminescent Co(CN)6 3– components.

“…[121] Eight D-A NDI/POM hybrids were synthesized by adjusting the metal ions and diffusion methods, in which POMs acted as electron donors, while 1D or 2D NDI coordination networks acted as electron acceptors (Figure 28). [122] Single-crystal X-ray diffraction analyses revealed that there are three categories of isostructures with layer, sandwich, and interpenetrating packing patterns. In particular, those photochromic properties were mainly associated with packing patterns.…”

Just as the heterojunctions in physics, donor–acceptor (D‐A) heterostructures are an emerging class of photoactive materials fabricated from two semiconductive components at the molecular level. Among them, D‐A hybrid heterostructures from organic and inorganic semiconductive components have attracted extensive attention in the past decades due to their combined advantages of high stability for the inorganic semiconductors and modifiability for the organic semiconductors, which are particularly beneficial to efficiently achieve photoinduced charge separation and transfer upon irradiations. In this review, by analogy with the heterojunctions in physics, a definition of the D‐A heterostructures and their general design and synthetic strategies are given. Meanwhile, the D‐A hybrid heterostructures are focused on and their recent advances in potential applications of photochromism, photomodulated luminescence, and photocatalysis summarized.
