The derivative compound of 2,4,6-triarylpyridine was synthesized in two steps. The
target compound was tested as colorimetric chemosensor against formaldehyde and the limit of
detection was also determined using spectrophotometer UV-vis. The first step of the synthesis
was the formation of 4-phenyl-2,6-bis(4-nitrophenyl)pyridine compound (1) from
4-nitroacetophenon and benzaldehyde. The second step of the synthesis was the formation of
4-phenyl-2,6-bis-(4-aminophenyl)pyridine (2) from reduction of the nitro group in compound 1
by HCl 37% solution and Sn metal. Compound 1 and 2 were characterized by spectrometers
FTIR, 1H NMR and direct inlet-mass spectrometry. The results showed that compound 1 was
synthesized with a yield of 78.3% and compound 2 with a yield of 68.9%. Compound 2 as
chemosensor showed color transition from colorless to yellow in chemosensor test against
formaldehyde in ethanol solvent. The limit of detection of formaldehyde was measured as
4.7×10-3 M using spectrophotometer UV-vis.
