New, water-soluble BODIPY dyes have been readily obtained from various cores by reactions involving the introduction of novel sulfonated peptide chains either coupling or substitution to give dimethylpropargylamine derivatives subsequently quaternized reaction with propanesultone.

A multifunctional silicon-containing hyperbranched epoxy is explored. The polymer can not only toughen BMI resins, but also emit blue photoluminescence.

Bright blue fluorescence-emitting hyperbranched polysiloxane simultaneously carrying unconjugated carbon–carbon double bonds and hydroxyl groups is reported for the first time.

Nonconventional fluorescent polymers without π-aromatic structure have attracted extensive interest in recent years. Hyperbranched polyesters are generally known because of their industrial applications; however, the luminescent properties polyester has not been reported. Herein, we synthesized a series fully biobased aliphatic hyperbranched via one-pot A2 + B3 esterification reaction. Intriguingly, resultant carrying no conventional units exhibited unexpected bright blue fluorescence under...

The synthesis and preliminary bio-conjugation studies of a novel water-soluble red-emitting di-styryl BODIPY dye are disclosed. Aggregation behaviour this compound under physiological conditions was suppressed by specific introduction di-sulfonated peptide-based linker at the meso phenyl substituent, sultonated styryl arms short polyethyleneglycol chains boron center. Thus, good quantum yield 22% in PBS for obtained. Introduction an activated ester function enabled successful to monoclonal...

In this Communication, novel water-soluble hyperbranched polysiloxanes (WHPSs) simultaneously containing hydroxyl and primary amine groups are developed. The polymers constructed via melt polycondensation, that is, transesterification reaction between ethoxyl of (3-aminopropyl)triethoxysilane dihydric alcohols, using a one-step process under catalyst-free conditions. Surprisingly, the resultant WHPSs can emit bright blue fluorescence in 100% solid state irradiation UV light, their...

ABSTRACT Fluorescent polymers without π‐aromatic structure have been a hot spot in recent years. Polycarbonate has applied industry for many years; however, the fluorescent behavior of polycarbonate not reported yet. Therefore, kind hyperbranched (HBPC) synthesized under solvent and catalyst‐free condition. Unexpectedly, novel HBPC containing no conventional chromophores exhibits unimagined bright blue fluorescence irradiation 334 nm UV light. The intensity is rising step with its...

A blue fluorescence‐emitting hyperbranched polysiloxane simultaneously containing hydroxyl and epoxy groups (HPHEp) has been developed through one‐step 2 + B 3 melt polycondensation between methoxyl of (3‐glycidyloxypropyl)trimethoxysilane (A‐187) neopentyl glycol under catalyst‐free conditions. The emission intensity the HPHEp in ethanol solution continuously arises pace with raising its concentration, brightest luminescence is observed even 100% solid state. Studies show that aggregation...

In this work, we prepared a novel hyperbranched polysiloxane containing carbon dots, which can emit near white light with the CIE chromaticity coordinates of (0.301, 0.333) <italic>via</italic> mixing dual emission at 414 and 532 nm excited <italic>λ</italic>_ex = 340 nm.

Development of an innovative strategy to prepare hyperbranched polysiloxanes (HBPS) is highly desirable due the significant shortcomings conventional fabrication approaches: precursors need pre‐synthesis, hydrosilylation reaction conducted using costly catalysts, and hydrolysis organosiloxanes easily results in gelation. Here, novel HBPS containing acetoacetyl groups (HBPS‐Ac) are synthesized through a cost‐efficient controllable transesterification reaction. It shown by gel permeation...

Two hydrosoluble aliphatic tertiary amine-containing hyperbranched polysiloxanes are explored. The resulting conventional chromophore-free polymers, without any treatment, such as acidification or oxidation, can emit bright blue fluorescence.

PZD/rGO/MoS₂ hybrid nanoparticles were prepared by a one-pot noncovalent method, and then incorporated into BMI resin as additive to fabricate PZD/rGO/MoS₂/BMI composites.

A novel reactive phosphorus-containing flame retardant was synthesized and used to modify bismaleimide resin. According investigations, the modified resin has good mechanical properties, thermal stability retardancy.

The current COVID-19 pandemic has had a huge impact on global health security, and some developed countries have promoted "vaccine nationalism" based the principle of self-interested supremacy adopted approach seizing pre-sale opportunities in procurement vaccines competing for right to distribute obstruct fair reasonable distribution worldwide. This article analyses situation predicament caused by Middle East which bear brunt influence detrimental vaccine nationalism. By analysing...
