Advanced Materials, Volume 37, Issue 13, April 2, 2025.A single object with dual properties – degradable and non‐degradable – is fabricated in a single print simply by switching the printing colors. The advanced multi‐material printing is enabled by the combination of a fully wavelength‐orthogonal photoresin and a monochromatic tunable laser printer, paving the way for precise multi‐material ...

Temperature‐ and pH‐Responsive Polymeric Photocatalysts for Enhanced Control and Recovery
Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022 Stimuli‐responsive photocatalytic materials have emerged that are not only able to efficiently catalyze reactions but can use external stimuli to modulate their physical properties. This technique has been used to control the reactivity of a photocatalytic material turning it on/off. Moreover, photocatalytic materials have been synthesized which can be

Excitation transfer and luminescence in porphyrin-carbon nanotube complexes [PDF]
arXiv, 2007 Functionalization of carbon nanotubes with hydrosoluble porphyrins (TPPS) is achieved by "$\pi$-stacking". The porphyrin/nanotube interaction is studied by means of optical absorption, photoluminescence and photoluminescence excitation spectroscopies. The main absorption line of the porphyrins adsorbed on nanotubes exhibits a 120 meV red shift, which ...

Photolysis of methylcobalamin. Nature of the reactive excited state [PDF]
, 1993 Photolysis of methylcobalamin (Co(III)corrin(CH3)L + H2O + O2 â > Co(III)(H2O)L + H2CO + OH-) shows a pronounced wave-length dependence. It is suggested that the reactive excited state is of the ligand-to-ligand charge transfer (LLCT) type and involves ...
