文摘

The iridium(III) complex 1 operates as a versatile platform for molecular logic gates fulfilling multiple logic functions depending on the inputs and the interrogation channels. In the UV-vis channel, it works as an INH, OR, and NINH gate with F− and H₂PO₄− as inputs when following the absorbance at 244, 262, and 457 nm, respectively. More importantly, the combination of photoluminescence (PL) intensity ratio (I₇₀₀/I₆₀₀) and transmittance at 457 nm resulted in the setup of a 1:2 demultiplexer with F− and CO₂ as inputs. Finally, a three-input (BF₃, F−, and H₂PO₄−) full subtractor was realized by integrating the electrochemiluminescence (ECL) intensity at 642 nm and the absorbance at 262 nm.
