Multistimuli-Responsive Luminescence of Naphthalazine Based on Aggregation-Induced Emission
Stimuli-responsive luminescent materials, which are dependent on changes in physical molecular packing modes, have attracted more and more interest over the past ten years. In this study, 2,2-dihydroxy-1,1-naphthalazine was synthesized and shown to exhibit different fluorescence emission in solution and solid states with characteristic aggregation-induced emission (AIE) properties. A remarkable...
متن کاملTunable light emission from co-assembled structures of benzothiadiazole molecules.
Co-assembled structures possessing tunable light emission from 510-690 nm have been prepared using various compositions of two different 4,7-substituted benzothiadiazole molecules, 1 and 2. The preferential incorporation and co-localization of 1 and 2 to produce co-assemblies are possible because of structural similarities and allow for tuning of morphology and light emission.
متن کاملDynamic behaviors of vimentin induced by interaction with GlcNAc molecules.
The cytoskeleton protein vimentin is dramatically altered following pathological events such as fibrosis and tumorigenesis. Vimentin binds to multivalent N-acetylglucosamine (GlcNAc) molecules at the cell surface and interacts with O-linked β-GlcNAc proteins. Moreover, dying cells can be engulfed by neighboring cells through surface interactions between vimentin and many O-GlcNAc proteins in ce...
متن کاملRecent progress in research on stimuli- responsive circularly polarized luminescence based on -conjugated molecules*
This short review article summarizes recent progress in research on various stimuli-responsive circularly polarized luminescence (CPL) properties derived from π-conjugated molecules and related materials. As representative examples, assembled structures of chiral π-conjugated polymers and molecules showed tunable CPL resulting from the enhancement of chirality induction by aggregation. Fascinat...
متن کاملMechano-responsive gelation of water by a short alanine-derivative.
We report the design of a structurally concise alanine derivative (Ala-hyd) that has a rotationally flexible aromatic N-protecting group for alanine and a hydrazide functionality at its carboxylic end. Ala-hyd requires mechanical agitation (physically stirring, vortexing or sonicating) to form supramolecular hydrogels at medium concentrations (0.4-0.8 wt%). At higher concentrations (>0.8 wt%), ...
