Seeing sense : The detection of detailed absorption and emission responses caused by amines, CO, and NO x is possible using an inexpensive array of porphyrins as sensors combined with a computer screen and web camera. The computer‐screen image shows the array in the presence of triethylamine. [Zn]=[Zn(tpp)], [Fe]=[Fe(tppCl)] (tpp=5,10,15,20‐tetraphenylporphyrin), BD=2,3,17,18‐tetraethyl‐7,8,12,13‐tetramethyl‐ a , c ‐biladiene dihydrobromide.
