Synthesis and photophysical properties of phenanthroimidazole-triarylborane dyads: intriguing ‘turn-on' sensing mediated by fluoride anions

Phenanthroimidazole-based triarylborane compounds with an N-phenyl (1Ph, 2Ph) or N-biphenyl (1BP, 2BP) bridge were synthesized and characterized. All four compounds exhibit a dual emission pattern in their photoluminescence (PL) spectra, which can be separated into high- (λem = ca. 380 nm in THF) and low-energy (λem = ca. 480 nm) emissions. While the high-energy emission remains largely unchanged in different organic solvents, the low-energy emission exhibits clear signs of positive solvatochromism. The results of the photophysical analysis and theoretical calculations suggest that the high-energy emission corresponds to a π-π* transition band arising from the phenanthroimidazole, whereas the low-energy emission originates from an intramolecular charge transfer (ICT) transition between phenanthroimidazole and the triarylborane moiety. UV-vis titration experiments examining the association of 1Ph, 2Ph, 1BP, and 2BP with fluoride demonstrate that these compounds associate with a 1?:?1 binding stoichiometry in THF and binding constants (Ka) that are estimated to be around 1.0-3.0 × 104 M?1. These compounds show a ratiometrically increased fluorescence response in PL titration experiments upon binding of fluoride to the borane moiety, thereby giving rise to a ‘turn-on' chemosensor for detection of fluoride anions. The ‘turn-on' properties can be judged as a result of the reinforcement of π-π* transition on phenanthroimidazole and the restriction of ICT transition to triarylborane.

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.
