Abstract: Embodiments of the present disclosure describe a negative photochromatic material. Embodiments of the present disclosure further describe a method of tuning a negative photochromatic material comprising selecting an amine donor group, selecting an acceptor group, and contacting at least the selected amine donor group and the selected acceptor group to form a negative photochromatic material, wherein one or more of the selected amine donor group and the selected acceptor group tune at least an absorption range of the negative photochromatic material.

Abstract: Embodiments of the present disclosure describe a colorimetric sensor comprising a substrate including an activated furan and configured to undergo a color change upon detecting an amine. Embodiments of the present disclosure describe a method of using a colorimetric sensor comprising applying an activated furan to a substrate, providing the substrate to a medium, and detecting an amine in the medium via change in color of the substrate. Embodiments of the present disclosure further describe a method of detecting an amine comprising contacting furfural with a cyclic acceptor group to form an activated furan for detecting amines, and contacting the activated furan with an amine to produce a colored donor-acceptor Stenhouse adduct.
