Measuring forces inside cells is particularly challenging. With the development of quantitative microscopy, fluorophores which allow measurement became highly desirable. We have previously introduced a mechanosensitive flipper probe, responds to change plasma membrane tension by changing its fluorescence lifetime and thus allows imaging FLIM. Herein, we describe design, synthesis, evaluation probes that selectively label intracellular organelles, i.e., lysosomes, mitochondria, endoplasmic...
We synthesized a series of CoFe Prussian blue analogues along which we tuned the amount cesium cations inserted in tetrahedral sites structure. Structure and electronic structure have been investigated, combining XANES, infrared spectroscopy, powder X-ray diffraction experiments, magnetization measurements. The change induced by light shows that efficiency photoinduced magnetization, evidenced few years ago similar compounds Hashimoto et al. (Sato, O.; Iyoda, T.; Fujishima, A.; Hashimoto, K....
The implementation of artificial molecular machines in polymer science is an important objective that challenges chemists and physicists order to access entirely new class smart materials. To design such systems, the amplification a mechanical actuation from nanoscale up macroscopic response bulk material central issue. In this article we show bistable [c2]daisy chain rotaxanes (i.e., muscles) can be linked into main-chain Upy-based supramolecular polymers. We then reveal by depth...
The implementation of molecular machines in polymer science is high interest to transfer mechanical motions from nanoscale macroscale order access new kinds active devices and materials. Toward this objective, thermodynamic topological aspects need be explored for reaching efficient systems capable producing a useful work. In paper we describe the branched polymerization pH-sensitive bistable [c2] daisy chain rotaxanes by using copper(I)-catalyzed Huisgen 1,3-dipolar cycloaddition ("click...

During mitochondrial fission, key molecular and cellular factors assemble on the outer membrane, where they coordinate to generate constriction. Constriction sites can eventually divide or reverse upon disassembly of machinery. However, a role for membrane tension in although speculated, has remained undefined. We capture dynamics constricting mitochondria mammalian cells using live-cell structured illumination microscopy (SIM). By analyzing diameters tubules that emerge from implementing...
Abstract An acid–base switchable [ c 2]daisy chain rotaxane terminated with two 2,6‐diacetylamino pyridine units has been self‐assembled a bis(uracil) linker. The complementary hydrogen‐bond recognition patterns, together lateral van der Waals aggregations, result in the hierarchical formation of unidimensional supramolecular polymers associated bundles muscle‐like fibers. Microscopic and scattering techniques reveal that mesoscopic structure these depends on extended or contracted states...

Abstract Planarizable push–pull probes have been introduced to demonstrate physical forces in biology. However, the donors and acceptors needed polarize mechanically planarized are incompatible with their twisted resting state. The objective of this study was overcome “flipper dilemma” chalcogen‐bonding cascade switches that turn on only response mechanical planarization probe. This concept is explored by molecular dynamics simulations as well chemical double‐mutant cycle analysis. Cascade...
We present a novel light-frozen dynamic covalent polymerization methodology to synthesize conjugated polymers based on BisAzaCoroneneDiimides (BACDs). This metal-free process converts reversible poly-imines into kinetically locked using visible light, generating minimal side-products. By incorporating aldehyde-functionalized comonomers, the approach enables creation of diverse n-type semiconducting with tunable optical band gaps and low LUMO levels. The exhibit exceptional thermal,...
The French 2022 Urolithiasis(CLAFU) Guidelineswere recently released. We aimed to evaluate the impact and diffusion of these CLAFU guidelines among Urologists. certified in-training Urologists were invited participate in an online survey between April May 2024, including 18 questions assessing demographics, practice trends, awareness new guidelines, their dissemination on daily practice. After being reviewed by a expert panel, circulated through social media/mail. Statistics included...

A logic gate based on a bistable [c2] daisy chain rotaxane decorated with lateral triarylamine units is described, giving rise to an INHIBIT function using proton concentration and light as inputs, producing dual color change supramolecular self-assembly outputs.
Abstract A new end‐to‐end azido double‐bridged copper(II) complex [Cu 2 L (N 3 ) ] ( 1 was synthesized and characterized (L=1,1,1‐trifluoro‐7‐(dimethylamino)‐4‐methyl‐5‐aza‐3‐hepten‐2‐onato). Despite the rather long CuCu distance (5.105(1) Å), magnetic interaction is ferromagnetic with J = +16 cm −1 H =− JS S ), a value that has been confirmed by DFT high‐level correlated ab initio calculations. The spin distribution studied using results from polarized neutron diffraction. This first such...
AzaBenzannulated perylenediimide (AzaBPDI) dyes were synthesized in high yields via a new reaction sequence involving an imine condensation followed by visible light-induced photocyclization. The large scope and efficiency of this alternative to the Pictet-Spengler are demonstrated, allowing easy preparation dimeric AzaBPDI as potential non-fullerene acceptors for organic solar cells.
We present novel insight on like-spin domains (LSD) in cooperative spin transition solids by following the photo-transformation and subsequent relaxation of a [Fe(ptz)6](BF4)2 single crystal vicinity light-induced instability. Self-organization under light is observed, accompanied Barkhausen-like noise jumps which reveal presence elastic interactions between LSDs. The phase separation process discussed terms dynamic potential providing spinodal instability corresponding temperature range....
The use of perylenediimide (PDI) building blocks in materials for organic electronic is considerable interest. This popular n-type semiconductor tuned by introducing peripheral groups their ortho and bay positions. Such modifications radically alter optoelectronic properties. In this article, we describe an efficient method to afford regioisomerically pure 1,6/7-(NO2 )2 - (NH2 -PDIs employing two key steps: the selective crystallization 1,6-(NO2 -perylene-3,4,9,10-tetracarboxy...
