Vapors of small molecules are under widespread study in natural signalling, environmental monitoring, industrial quality control, and in medicine.[1–3] In the last few decades, advances in chemistry and material science have enabled the development of chemical sensors of such volatile organics,[4–7] in which conjugated polymers and cross-reactive chemical sensor arrays are the most widespread sensor types. Among them, optical vapor sensing arrays based on luminescence (including fluorescence) and absorbance have become essential.[8–13] In the recent past, colorimetric detection of volatile organics using crossreactive chemical sensors have been demonstrated in multiple applications.[14–16]Although absorbance–based methods for vapor detection have shown good success, fluorescence-based methods may offer some advantages, such as high sensitivity and low background. For example, the detection of vapors of nitroaromatics with conjugated polymers and bio-polymers has showed very high sensitivity.[17–23] Notably, much of the power of fluorescence-based detection still remains unharnessed, since most current approaches involve the use of only one type or a few types of sensor molecules, resulting in a limited diversity of sensing (ie, quenching).[19, 20] Additionally, in most current approaches the difficulty of synthesis of a set of sensor molecules and the lack of flexibility in conjugating them to supports can restrict their general utility.
