Theoretical Design of Near-Infrared Fluorescent Sensor for F Anion Detection Based on 10-Hydroxybenzo[h]quinoline Backbone.

ABSTRACT: Proper design and development of near-infrared (NIR) fluorescent sensors is very important for applications in vivo. In this work, we theoretically designed a ratiometric and NIR fluorescent sensor based on the 10-hydroxybenzo[h]quinoline (HBQ) backbone via systematically investigating the substituent effects of electron-donating groups (-NH₂, -CH₃, -C(CH₃)₃) and electron-withdrawing groups (-NO₂, -CN, -F, -Cl, -CF₃) at the proton donor site on the proton transfer process in HBQ in both the S₀ and the S₁ states. According to the calculated potential energy profiles along the proton transfer as well as the photophysical properties among all the derivatives, we successfully screened out that 7NH
