Chemiresistors based on SWCNT networks decorated with an oxygen-sensitive Eu3+-containing dendrimer complex. (a) Chemical structure of the europium containing dendrimer complex (Eu8) containing eight Eu3+ cations coordinated within a 1,8-naphthalimide-terminated, G3-PAMAM dendrimer core. (b) Electrical response rate of the Eu8-SWCNT chemiresistor to increasing oxygen concentration. (c) Comparison of the normalized conductance between Eu8-SWCNTs (black curve) and pristine SWCNTs (green curve) when exposed to illumination with 365 nm ultraviolet light in flowing N2, pure O2, 10.5% CO2, 100 ppm NH3, and 10 ppm NO2.
