We herein propose a proof of concept full dual-band electrochromic (EC) device able to selectively modulate solar light between 300 and 1600 nm. Dual-band control was achieved by exploiting the complementarity cooperation two earth-abundant nontoxic transition metal oxide nanocrystalline materials absorb different spectral regions when electrochemically charged. The active were obtained through microwave-based synthetic protocol produce massive amounts ligand-free water-soluble TiO2@WO3–x...
Three fluorenone-based two-photon fluorescent probes for specific targeting of lysosomes and mitochondria in cancer cells.
Three new metal-free organic dyes with the [1]benzothieno[3,2-b]benzothiophene (BTBT) π-bridge, having structure donor-π-acceptor (D-π-A) and labeled as 19, 20 21, have been designed synthesized for application in dye-sensitized solar cells (DSSC). Once design of π-acceptor block was fixed, containing BTBT π-bridge cyanoacrylic group electron acceptor anchoring unit, we selected three donor units different electron-donor capacity, order to assemble chromophores high molar extinction...
Abstract Poly(arylenevinylene) polymers bearing fluorine atoms in the vinylene units were obtained by a Stille cross‐coupling reaction of ( E )‐(1,2‐difluoro‐1,2‐ethenediyl)bis(tributylstannane) with diiodoaryl derivatives. The introduction on double bond stannane leads to relatively high molecular weights. Furthermore, presence fluorinated changes optical properties and shifts emission towards blue region visible spectrum. A analogue MEH‐PPV was obtained, it shows photoluminescence that is...
New compounds based on heptazine core bearing phenoxazines substituent were synthesized, starting from the easily accessible 2,5,8-tri(3,5-diethyl-1H-pyrazolyl-1-yl)heptazine. The pyrazolyl groups substituted by one, two, or three phenoxazines, yielding H1, H2, H3. Heptazine (Hz) being an exceptionally strong electron acceptor and donors, these novel are expected to exhibit low-lying singlet triplet states of pronounced charge-transfer (CT) character. excited-state electronic structures...
In this study, we explore the solid-state photophysical properties of four donor-acceptor-donor’ (D-A-D’) fluorinated benzonitrile compounds, featuring combinations phenoxazine and carbazole donor units. We have previously shown that these...
The irreversible reaction of methyl triflate with neutral Re(I) tetrazolato complexes the type fac-[Re(diim)(CO)3(L)], where diim is either 1,10-phenanthroline or 2,2'-bipyridine and L a para substituted 5-aryltetrazolate, yielded corresponding cationic methylated complexes. While methylation occurred regioselectively at N4 position tetrazole ring, were found to exist in solution as equilibrating mixtures linkage isomers, Re(i) centre was bound N1 N2 atom ring. existence these isomers...
Colloidal white emitting nanostructures were successfully fabricated by covalently binding a blue oligofluorene at the surface of silica beads, that incorporate orange luminescent colloidal CdSe@ZnS quantum dots (QDs). White light was achieved carefully tuning size QDs to complementarily match emission color fluorophore and taking into account delicate balance between in core beads amount organic dye bound surface. The proposed approach is highly versatile as it can be extended fabrication...
Abstract Hybrid organic–inorganic perovskites (PVKs) are among the most promising materials for optoelectronic applications thanks to their outstanding photophysical properties and easy synthesis. Herein, a new PVK‐based thermochromic composite is demonstrated. It can reversibly switch from transparent state (transmittance > 80%) at room temperature colored < 10%) high temperature, with very fast kinetics, taking only few seconds go bleached (and vice versa). X‐ray diffraction,...
Bio-based polymers are attracting great interest due to their potential for several applications in place of conventional polymers. In the field electrochemical devices, electrolyte is a fundamental element that determines performance, and represent good candidates developing solid-state gel-based electrolytes toward development full-solid-state devices. this context, fabrication characterization uncrosslinked physically cross-linked collagen membranes reported test as polymeric matrix gel...
A platform is described for the first time facile synthesis of oligo‐ and polythiophene‐S‐oxides corresponding ‐S,S‐dioxides in short times, mild conditions, high yields. Employing ultrasound assistance, brominated thiophenes are selectively mono‐ or dioxygenated at room temperature. These building blocks then combined with metalated via microwave‐assisted cross‐coupling reactions through a “Lego‐like” strategy to afford unprecedented oligo/polythiophene‐S‐oxides mixed...
