Abstract

Abstract The N-2-aryl-1, 2, 3-triazole derivatives (NATs) were developed as a new class of UV/blue-light-emitting fluorophores. Though both N-1-aryl-1, 2, 3-triazoles and N-2-aryl-1, 2, 3-triazoles gave strong photo absorption under excitation at 330 nm, only the N-2-analogous showed strong fluorescence emission in the UV/blue range with high efficiency in various solvents (quantum yield Φ around 0.3–0.5). Significant substituted group effects were ...
