AI Article Synopsis

  • A new type of multicolor emissive material was created using a single luminophore, a Lewis acid, and their complex.
  • The emission colors can be adjusted by varying the concentration of the solution and the ratios of the mixed solvents.
  • By changing the amount of the complex in the polymer, researchers achieved different colors in solid-state, including white emission, by balancing the interactions among the luminophore, Lewis acid, and complex.

Article Abstract

Multicolor emissive materials consisting of a single luminophore, a Lewis acid, and their complex were developed. The emission colors can be tuned by changing the concentration of the solution and the ratio of mixed solvents. Various emission colors in the solid state were observed when the complexes were added to polymers in different amounts. The color change is due to equilibrium disruption between the single luminophore, the Lewis acid, and the complex thereof. White emission was observed by appropriately controlling the equilibrium by changing the amount of the complex in the polymer.

High-performance, environmentally friendly indium phosphide (InP)-based quantum dots (QDs) are urgently needed to meet the demands of rapidly evolving display and lighting technologies. By adopting the highly efficient and cost-effective one-pot method and utilizing aluminum isopropoxide (AIP) as the Al source, a series of Al-doped InP/(Al)ZnS QDs with emission maxima ranging from 480 to 627 nm were synthesized. The photoluminescence quantum yield (PLQY) of the blue, green, yellow, orange, and red QDs, with emission peaks at 480, 509, 560, 600, and 627 nm, reached 34%, 62%, 86%, 96%, and 85%, respectively.

Developing hybrid fluorescence (FL)/room-temperature phosphorescent (RTP) materials in dry-state, aqueous, and organic solvents holds paramount importance in broadening their applications. However, it is extremely challenging due to dissolved oxygen and solvent-assisted relaxation causing RTP quenching in an aqueous environment and great dependence on SiO-based materials. Herein, an efficient endogenetic carbon dot (CD) strategy within melamine-formaldehyde (MF) microspheres to activate RTP of CDs has been proposed through the pyrolysis of isophthalic acid (IPA) molecules and branched-chain intra-microspheres.

Induction of systemic acquired resistance (SAR) in plants to control bacterial diseases has become an effective solution to the problems of agrochemical resistance and ecological environment damage caused by long-term and large-scale use of traditional bactericides. However, current SAR-inducing compounds are often unable to rapidly eliminate pathogenic bacteria in infected plant tissues to prevent further spread of the disease, severely restraining the potential for extensive application in agriculture. Herein, we address the limitations by developing a series of visible-light-absorbing aggregation-induced emission photosensitizers suitable for agricultural use.
