Abstract:
A method of detecting the presence of an amine compound in a fingerprint, the method comprisingcontacting the amine compound with a composition comprising a molecule having the chemical structure of Formula I to form a product, ##STR11## wherein each of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 is independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl substituent, an alkenyl substituent, a carboxy substituent, a carboalkoxy substituent, a carbaldehyde substituent, an oxo substituent, a cyano substituent, a thiocyano substituent, a nitro substituent, a nitroso substituent, a boronic acid substituent, a boric acid ester substituent, a dihydroxyphosphonyl substituent, a hydroxy substituent, an alkoxy substituent, an aryloxy substituent, an alkenyloxy substituent, a dialkylamino substituent, an arylalkylamino substituent, a diarylamino substituent, an alkenylamino substituent, a sulffiydryl substituent, an alkylthio substituent, an arylthio substituent, an alkenylthio substituent, a sulfonate substituent, a silyl substituent, an alkylsilyl substituent, an alkylarylsilyl substituent, an arylsilyl substituent, a siloxy substituent, an alkylsilyloxy substituent, an arylsilyloxy substituent, an unsubstituted aryl substituent, a substituted aryl substituent, and an unsubstituted heteroaryl substituent, and wherein any adjacent two of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 can, together, be a cyclic substituent;assessing an optical property of the product, wherein the optical property is selected from the group consisting of absorbance and fluorescence, andcomparing the optical property of the product with the same optical property of the composition, whereby a difference between the optical property of the product and the same optical property of the composition is an indication that the amine compound is present.
