Pointlike Material Accumulation and Displacement in Azopolymer Thin Films Driven by Spatial Light Modulation

Advanced Optical Materials, EarlyView.
A maskless, SLM‐driven approach enables the deterministic inscription of arbitrary topographical features in azopolymer films by mapping complex vectorial light fields onto local viscoplastic stress. This platform allows for the rapid generation and dynamic erasure of high‐aspect‐ratio micro‐spikes, offering a versatile tool for reconfigurable flat ...

Terpyridine ruthenium complexes as building blocks for new metallo-supramolecular architectures

, 2004
Supramolecular architectures are of great interest in modern materials research. The directed synthesis of asym-metric 2,2':6',2''-terpyridine ruthenium(II) complexes is an important tool towards such systems.

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

Advanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Twisting Lamellae Triggering Circular Polarized Luminescence of Chromophoric Moieties in Banded Spherulites With Evolution of Homochirality

Advanced Optical Materials, EarlyView.
Crystallization‐mediated hierarchical chirality is shown to transform molecular stereochemistry into macroscopic circularly polarized luminescence. Twisted PLA crystalline lamellae generate asymmetric surface stress and chiral steric environments that direct achiral chromophore organization, producing opposite CPL responses in PLLA and PDLA matrices ...

Molecular Appendix Adjusted Architectural Propagations of Red‐Light Controlled Macroscopic Photoactuating Performances

Advanced Robotics Research, EarlyView.
Amphiphilic chloroazobenzenes, bearing different amino acids as end groups alanine, phenylalanine, and valine, exhibit excellent photoisomerizations. Varying structures of three amino acid groups participate in supramolecular formations and therefore photoinduced morphological transformations via adjusting intermolecular interactions. These interaction

Supramolecular Ligands in Gold(I) Catalysis

, 2013
A supramolecular ligand-template strategy is applied to gold(I) catalysis. The supramolecular ligands, formed from a phosphoramidite backbone and two templates, display different regioselectivity in the hydroalkoxylation of allenes compared to non ...
