This article describes the synthesis and photoluminescent properties of novel α-amino acids, in which the chromophores containing biaryl benzotriazinone exhibit dual emission fluorescence through locally excited (LE) and twisted intramolecular charge transfer (TICT) states. The intensity of each emission band can be controlled by the electronics and position of the substituents, and this led to the design of a 2-methoxyphenyl analogue that, due to twisting, displays bright TICT fluorescence, solvatochromism, and pH sensitivity.
