“…[112] In addition, since some of tin compounds can show cytotoxicity, biological applications as a theranostic drug which can show luminescence and bioactivity have been explored. [113] In the azo-based tridentate ligands, the azobenzene moiety of the silicon compound (46SiH) [114] showed a pedal motion in crystal [115] and the emission property was not obtained. On the other hand, tin compounds (46SnH [116] and 46SnBr [117] ) were found to have efficient luminescence, and in particular, introduction of substituents at the azo moiety greatly enhanced luminescence efficiency (46SnBr).…”

π‐Conjugated compounds exhibit remarkable photophysical properties, such as strong light absorption and emission, and are applicable to organic devices, bioimaging, and sensing systems. The introduction of p‐block elements into π‐conjugated systems is presumable as a critical strategy for modulating their properties. Nevertheless, the type of utilized elements has been limited to the second and third‐period ones because it is difficult to construct critical electronic interactions between heavier atoms and carbon‐based π‐conjugated scaffolds. On the other hand, it has been recently suggested that the heavier p‐block elements are able to induce significant changes in the optoelectronic properties of π‐conjugated systems thanks to their large size, high polarizability, and heavy atom effect. Although there are much room to explore effects of heavy‐atom substitution on physical and electronic properties of conjugated systems, various characters have been discovered. Hence, this review mainly focuses on the relationships between the types of p‐block elements and the optical properties of their representative complexes and organoelement compounds, particularly light absorption and emission.

Although many researchers have devoted their much effort to establish the strategy for developing a stimuli‐responsive molecule and tuning of their properties according to the preprogrammed design, it is still challenging to create desired molecules from the scratch. We recently demonstrated that the molecules with a large structural difference between the theoretically optimized structures in the ground and excited states have a potential to exhibit stimuli‐responsive luminescent properties. We defined these molecules as an excitation‐driven molecule and have shown that they are a versatile platform for designing stimuli‐responsive luminescent molecules. Herein, based on the concept of excitation‐driven molecules, we show that the hypervalent tin‐fused azomethine (TAm) compounds possessing aggregation‐induced emission (AIE) properties can be obtained by simple chemical modification with a methyl group although conventional TAm derivatives are well known to be highly luminescent compounds in solution. Furthermore, by combining the solid‐state luminescence property of AIE and the coordination number shifts of the hypervalent tin atom, the thermoresponsive films operating below the freezing point are fabricated with the polymer. In this study, we apply the concept of excitation‐driven molecules to the hypervalent compounds and demonstrate to obtain the novel functional materials.
