A naphthalimide-based fluorescent gelator (N1) containing an alkenyl group has been designed and characterized. This material is able to gelate alcohols via a precipitate-to-gel transformation when triggered with ultrasound for less than 2 min (S-gel). The gelation process in n-propanol was studied by means of absorption, fluorescence, IR spectra, scanning electron microscopy (SEM) images, X-ray diffraction patterns. fluorescence intensity N1 decreased during the linear relationship...

Abstract Synthetic hydrogel strain sensors rarely exhibit a comprehensive combination of mechanical properties such as ultra‐stretchability, ultrafast self‐healing, and high sensitivity. Herein, seven small molecule enhanced behaviors polymer‐cluster based hydrogels are demonstrated. The oxidized polyethyleneimine/polymeric acrylic acid (ohPEI/PAA) with aromatic formic acids supramolecular cross‐linkers prepared by simultaneous formation ohPEI polymer clusters PAA upon the addition ammonium...

Using Pluronic P123 surfactant as template, a periodic mesoporous organosilica (PMO) functionalized with 4′-(4-carboxy-methyleneoxy phenyl)-2,2′:6′,2″-terpyridine (L-COOH) was successfully prepared via co-condensation using 1,2-bis(triethoxysilyl)ethane (BTESE) and the modified L-COOH (L-COOH-NH2). This terpyridine moiety forms interesting chelates to europium ions enhances luminescence of Eu3+ ions. Thus, novel luminescent hybrid material developed linking complex Eu(NTA)3(H2O)2...

A huge amount of data inundated in our daily life; there is an ever-increasing need to develop a new strategy information encryption-decryption-erasing. Herein, polymeric DCTpy/PAM hydrogel has been fabricated store via controllable Eu3+/Zn2+ ionoprinting for hierarchical and multidimensional decryption. Eu3+ Zn2+ have competition dynamic interaction toward DCTpy under NH3 stimuli the network. The Eu(III)/Zn(II)@DCTpy/PAM exhibits light red fluorescence due antenna effect. Upon addition NH3,...

A new kind of terpyridine-based Ca²⁺ sensor <bold>TS</bold> was designed and studied based on the internal charge transfer (ICT).

Herein, we report a novel fluorescent organogelator that could discriminate F⁻ from AcO⁻ in both solution and gel systems.

A Zr-cluster based metallogel is synthesized <italic>via</italic> an unusual one-pot solvothermal method. The gel displays outstanding mechanical and stimuli-responsive properties, which could be used as soft electrochromic devices.

The facile tuning of the fluorescent properties organogels is highly desirable for optical switches, light-emitting diodes, chemosensors and bioprobes. design organic molecules with multiple emission colors but only one molecular platform remains challenging. Herein, a new cholesterol-based organogelator N1 containing D-A pairs (salicylaldehyde naphthalimide units) was designed. We successfully obtained solvent-tuned in both solution gel states using unimolecular platform. Moreover, effects...

Herein, we reported a new kind of naphthalimide-based derivative (N1), which could undergo direct sol–gel transition accelerated by ultrasound in 2-methoxyethanol. The gels are very sensitive to the body temperature range from 35 42 °C, is scope clinical thermometer. gel-to-sol temperatures enhanced with increased concentrations gels. reversible gel-sol transition, together emission intensity and morphological changes, controlled be repeated many circles without fatigue. Therefore, gel...

We achieved an assembly of a Eu complex covalently bonded to different mesoporous silica (MCM-41 and SBA 15) two metallic alkoxides (Ti–O Al–O). The effect the matrices on luminescence behavior was investigated.

Macroporous chloromethyl polystyrene resin (MCPR) was modified by (2, 3, 4-) amino pyridine. Then Rhodium ( ) octanoate dimer (ROD) recovered the pyridine-modified resin. The adsorption and elution of ROD on were investigated. results showed 2-amino pyridine best one.

&lt;p&gt;One of two pedestrian suspension bridges with twin curved decks suspended by spatial unilateral hangers is described in detail. It was built Shanghai international tourism resort, which 120m long total and composed an outer main deck 6m width inside auxiliary 3m wide. Steel box girder fixed tensile bears at the abutments to resist torsion, inclined steel-­pipe piles were adopted for foundations pylons balance horizontal thrust soft ground.
