Kaneda N, Imato K, Sasaki A, Tanaka R, Imae I, Hirata T, et al.
Chem Sci . 2024 Nov; 15(48):20545-20555. PMID: 39600512
Molecular photoswitches have been incorporated into polymer backbones to control the macromolecular conformations by structural changes of the main-chain photoswitches. However, previous photoswitches installed in the main chains are thermolabile,...

Imato K, Hino T, Kaneda N, Imae I, Shida N, Inagi S, et al.
Small . 2023 Oct; 20(9):e2305067. PMID: 37858925
Soft actuators generate motion in response to external stimuli and are indispensable for soft robots, particularly future miniature robots with complex structure and motion. Similarly to conventional hard robots, electricity...

Imato K, Ishii A, Kaneda N, Hidaka T, Sasaki A, Imae I, et al.
JACS Au . 2023 Sep; 3(9):2458-2466. PMID: 37772185
Molecular photoswitches are extensively used as molecular machines because of the small structures, simple motions, and advantages of light including high spatiotemporal resolution. Applications of photoswitches depend on the mechanical...

Fumoto T, Tanaka R, Ooyama Y
Dalton Trans . 2023 Feb; 52(16):5047-5055. PMID: 36807366
Using bis(imino)acenaphthene (BIAN) zinc(II) and palladium(II) complexes with tetraphenylethene (TPE) units as bulky aryl groups, Zn-2 and Pd-2 have been designed and developed, and their photophysical properties in solution and...
