Abstract

Compound of 3,3'-(4-(2-amino-4,5-dimethoxyphenyl)pyridine-2,6-
diyl)dianiline (CHP) has been synthesized via three-step synthetic procedure from
veratraldehyde as starting material and 4-(4,5-dimethoxy-2-nitrophenyl)-2,6-bis(3-
nitrophenyl)pyridine (CHP-1) as an intermediate compound. The CHP-1 was reduced
using hydrazine hydrate catalyzed by 10% Pd/C to the final target of CHP. The
spectroscopic study revealed that CHP in acetonitrile could detect formaldehyde through
fluorescence enhancement and showed color change from yellow to blue under the 365
nm portable ultraviolet lamp as a response. Based on the fluorescence spectra, the
emission wavelength of CHP in acetonitrile was shifted from 526 to 480 nm after addition
of formaldehyde. Limit detection (LOD), selectivity, sensitivity, and computational study
geometry of CHP as a chemosensor for formaldehyde has also been investigated. CHP
could also be applied as a test paper for the detection of formaldehyde qualitatively.
