“…Especially, the redmost Qy maximum of 3 3 -phenyl substituted 1m was situated at 698 nm, which was longer than that of methyl pyropheophorbide-d (1a) possessing the 3-formyl group (695 nm) and the same as that of its derivative bearing a strongly electronwithdrawing trifluoroacetyl group at the 3-position. 26 …”

“…Several different techniques have been performed employing electrochemical sensors to real-time detection of amines in the atmosphere [8,[13][14][15]. Among the different techniques, colorimetric sensors do not require any power supply and the test results can be detected with the naked eye easily [16][17][18][19][20][21][22][23].…”

A simple colorimetric method for determination of vaporous aliphatic amines has been developed. Importantly, the recognition of vaporous aliphatic amines could be observed by naked eyes owing to color change of the synthesized azobenzothiazole-polyene dye from orange to dark blue in the solution. The results revealed that primary amines can form 1:2 and secondary amines 1:1 complexes with the dye, respectively. The sensing of this chemosensor is capable over a dynamic linear ranges between 10 -2 -10 -6 M for primary aliphatic amines and 10 -2 -10 -4 M for secondary aliphatic amines. The response of the dye to tertiary amines or aromatic amines was not strong enough to make a strong color change. Validation of the assay method revealed excellent performance characteristics, including high repeatability and highly recognizable color change.

“…Trifluoroacetyl-substituted stilbenes and azobenzenes form hemiacetals with amines, thus leading to blueshifted absorption and in some cases to enhanced emission. [10,11] Similarly, aldehyde groups attached to a coumarin dye detect and quantify amines. [12] If the reactive aldehyde component is attached to a recognition element that contains a boron functionality, catechol-A C H T U N G T R E N N U N G amine can be identified.…”

We demonstrate that aldehyde-substituted donor-acceptor cruciforms [1,4-bis(arylethynyl)-2,5-distyrylbenzenes] are useful dosimeters for primary amines, primary diamines, and secondary amines. The 1,n-diamines are particularly reactive towards this dosimeter and can be detected in less than 100 ppm concentration. Using a single aldehyde-functionalized cruciform in seven different solvents allowed us to discern fourteen different amines by digital photography and statistical evaluation of the response patterns extracted as red, green, blue (RGB) values.
