Engineering of aggregation-induced emission luminogens by isomeric strategy to achieve high-performance optoelectronic device

Achieving non-doped organic light-emitting diodes (OLEDs) with high electroluminescent (EL) performance is essential for both illumination source and display applications. A source of this difficulty is the aggregation-induce quenching effect of emitters

Dimethyl Sulfoxide-Free and Water-Soluble Fluorescent Probe for Detection of Bovine Serum Albumin Prepared by Ionic Co-assembly of Amphiphiles

Detection of bovine serum albumin (BSA) is an important issue in the sense of medical applications and enzymatic reactions; however, the recently developed fluorescent probes require the involvement of dimethyl sulfoxide (DMSO), which may be detrimental to proteins. In this study, we demonstrated a DMSO-free and water-soluble fluorescent probe prepared by ionic co-assembly of amphiphiles. The cationic amphiphile is a newly designed molecule (denoted by DPP-12) bearing a conjugated diketopyrrolopyrrole (DPP) and two tetraphenylethylene groups. It turns out that the fluorescence emission of DPP-12 depends on the amount of anionic amphiphilic sodium dodecyl benzene sulfonate (SDBS). The fluorescence intensity first increases and then decreases with the concentration of SDBS, and each branch presents a linear relationship. BSA consumes SDBS by the formation of complexes, thus leading to an increase of fluorescence intensity of the mixed solution of DPP-12 and SDBS. Therefore, the mixed solution of DPP-12 and SDBS was applied as a fluorescent probe to detect the low concentration of BSA by back-titration. This fluorescent probe does not require DMSO and has good tolerance to metal ions in blood and good photostability. The limit of detection is as low as 940 nM, almost 3 orders of magnitude lower than the content in organisms.

A series of new tetraphenylethylene monomer, dimer and three-dimensional trimer based triptycene-bridged triphenylethenes has been constructed. Their structures were clearly confirmed and the irregular fluorescent behaviors at different temperatures and s

Axial and peripheral tetraarylethylene-modified subphthalocyanines with distinctive fluorescent performances

Special aromatic structure and unique geometric characteristics make subphthalocyanines possess distinctive electronic structures and physicochemical properties. In this paper, tetraarylethylenes with aggregation-induced emission were introduced to subphthalocyanine macrocycles at the axial direction and the periphery to improve the fluorescence emission properties. Results show that the modification at the two different positions of the subphthalocyanines has different effects on regulating the fluorescence performances. The subphthalocyanine modified axially by tetraphenylethylene shows outstanding fluorescence resonance energy transfer (FRET) phenomenon, and the modification on the periphery of subphthalocyanine is conducive to enhance the fluorescence intensity. These distinctive performances have the potential applications in fluorescence sensor and probe.

Opposite ESIPT characteristic of two AIE-active isomers with different linkage sites

In this work, we report two isomers composed of 1-phenyl-1H-phenanthro[9,10-d]imidazole (PI), hydroxyl and tetraphenylethylene (TPE), abbreviated as m-PITPE and p-PITPE. It is found that they exhibit similar aggregation-induced emission (AIE) behavior but totally different excited-state intramolecular proton transfer (ESIPT) characteristic, as a result of the different linkage sites of PI on TPE moiety. Theoretical calculations and their different experimental responses to F? demonstrate that only the para-linkage isomer displays ESIPT. In m-PITPE with meta-linkage, the electron cloud distribution only locates at the TPE part in the singlet excited (S1) states, which results in the localized excited state without ESIPT characteristic.

Stepwise Suzuki?Miyaura Cross-Coupling of Triborylalkenes Derived from Alkynyl?B(dan)s: Regioselective and Flexible Synthesis of Tetrasubstituted Alkenes

Alkenes with three boryl groups of differing reactivities were synthesized and subsequently cross-coupled regioselectively with aryl halides in a stepwise manner to afford tetrasubstituted alkenes. The key triborylalkene is derived from the platinum-catalyzed diboration of alkynyl?B(dan)s with B2(pin)2. Due to excellent regioselectivity and reaction efficiency of each step starting with alkynyl?B(dan)s, tetrasubstituted alkenes with desired carbon frameworks at desired positions can be prepared in high yields. For example, an alkene with four distinct aryl groups, p-MeOC6H4, p-CF3C6H4, p-MeC6H4, and p-NCC6H4, was obtained in 71% overall yield via six steps, starting with the dehydrogenative borylation of p-MeC6H4C≡CH with HB(dan). Moreover, a variety of tetrasubstituted alkenes, including regio- and stereoisomers of the above tetraarylalkene, AIE-active TPTPE and derivatives thereof, and (Z)-tamoxifen, a well-known breast cancer drug, were accessed via the developed strategy. (Figure presented.).
