Functional polymer materials containing heavy group‐14 elements focusing on germanium and tin

open access: yesSmart Molecules, Volume 4, Issue 1, March 2026.
The synthesis, functions, and applications of the polymers containing heavy group 14 elements focusing on germanium and tin are outlined. Owing to their large atomic radii and weak binding energies, the polymers show unique properties: chromism, luminescence, carrier mobility, and reactivity to produce radials and higher coordinated states.

Preparation of Aqueous Solutions with Information on Solids Using Natural Polymers by Solid‐State Mixing

open access: yesThe Chemical Record, Volume 26, Issue 3, March 2026.
The solid‐state information, such as chiral crystal formation, crystal polymorphism, mechanochromism, room‐temperature phosphorescence, and fluorescence detection by molecular recognition, is maintained even when the functional guest molecules are solubilized in water using natural polymers.

Database of low‐temperature absorption and fluorescence spectra of native photosynthetic tetrapyrrole macrocycles

open access: yesPhotochemistry and Photobiology, Volume 102, Issue 2, Page 457-469, March/April 2026.
The absorption and fluorescence spectra at 77 K (frozen glass) and room temperature (fluid solution) are provided for 12 native photosynthetic macrocycles encompassing one porphyrin, eight chlorins, and 3 bacteriochlorins. Abstract Low‐temperature (77 K) absorption and fluorescence spectra of 12 naturally occurring photosynthetic tetrapyrrole ...
