Di-(2-picolyl)-N-(2-quinolinylmethyl)amine-Functionalized Triarylboron: Lewis Acidity Enhancement and Fluorogenic Discrimination Between Fluoride and Cyanide in Aqueous Solution

Triarylboron-based Lewis acids as fluoride sensors face a stimulating academic challenge because of the high hydration enthalpy of fluoride, and are usually influenced by a competing response for cyanide ion. Herein, we present a new triarylborane functionalized by a metal-ion ligand, di-(2-picolyl)-N-(2-quinolinylmethyl)amine, with subsequent metalation. In aqueous solution, this triarylborane (QB) can capture fluoride and cyanide anions through chelation induced by the synergy of boron and metal ions. Moreover, this triarylborane moiety acts as a fluorescent reporter of the binding, allowing for discrimination between fluoride and cyanide anions through dual-channel fluorescence changes. The different chelation models and fluorogenic responses of this sensor toward F? and CN? were verified by the single-crystal structures of 2-to-2 adduct for KCN and 1-to-1 for KF.

Synthesis and photophysical properties of new through-space conjugated luminogens constructed by folded tetraphenylethene

Through-space conjugation refers to a unique non-covalent electronic coupling interaction typically occurring between two face-to-face parallel aromatic units, which has shown great potential in constructing novel functional materials capable of multidimensional carrier and energy transportation. However, well-studied through-space conjugation systems are quite rare. In this work, a series of tailored through-space conjugated luminogens are readily constructed from the folded tetraphenylethene (TPE) core and common functional groups like fluorene, carbazole, imidazole and dimesitylborane. Systematic studies on their photophysical properties were conducted, and a deep insight into the structure-property relationship is gained. The new molecules show aggregation-enhanced emission (AEE) characteristics with high fluorescence quantum efficiencies of up to 54% in films. Through the binding experiments of fluoride ions with boron atoms, the impacts of through-space conjugation on the photophysical properties of the luminogens are carefully studied. All these results undoubtedly provide important clues to the rational design of efficient through-space conjugated materials with specific functions.

Bipolar micromolecular luminescent material based on 4-(9H-carbazole-9-yl) aniline and preparation method and application thereof

The invention discloses a bipolar micromolecular luminescent material based on 4-(9H-carbazole-9-yl) aniline and a preparation method and application thereof. The material is mainly characterized in that the 4-(9H-carbazole-9-yl) aniline is used as a hole transport center unit, and bipolar micromolecules with the 4-(9H-carbazole-9-yl) aniline as the center are obtained by selecting groups with an electron transmission function. The bipolar micromolecules prepared through the method can be used for making a luminescent layer of an organic light emitting diode.

Charge transfer emission in oligotriarylamine-triarylborane compounds

Donor-acceptor compounds exhibiting charge transfer emission are of interest in a variety of different contexts, for example, for nonlinear optical processes and for sensor applications. Recently investigated triarylamine-triarylborane compounds represent an important class of donor-acceptor systems, and we explored to what extent their charge-transfer properties can be further improved by using stronger amine donors and borane acceptors than prior studies. The oligotriarylamine employed here is a much stronger donor than previously used triarylamines containing single nitrogen centers. In order to increase the acceptor strength, the electron-accepting unit was equipped with two (instead of one) dimesitylboron substituents. In our comparative study, six donor-acceptor compounds were synthesized and investigated by cyclic voltammetry and optical spectroscopy. An increase of the donor strength through replacement of an ordinary triarylamine by an oligotriarylamine unit leads to the expected energetic stabilization of charge transfer (CT) excited states, but the emission solvatochromism is not more pronounced. The attempted increase of the acceptor strength by substitution of the acceptor moiety by two (instead of one) dimesitylboron groups leads to a drastic decrease of emission quantum yields. On the basis of these results, our purely experimental study provides fundamental guidelines for the design of new triarylamine-triarylborane donor-acceptor compounds with favorable charge-transfer emission properties.
