have achieved a simple and general method for acetalization of aldehydes by means of a photochemical reaction under low-energy visible light irradiation. A broad range of aromatic, heteroaromatic, and aliphatic aldehydes have been protected under neutral conditions in good to excellent yields using a catalytic amount of Eosin Y as the photocatalyst. Our visible light mediated acetalization strategies are

The present invention relates to a one-photon and/or two-photon fluorescent probe for selectively detecting hydrogen sulfide in the human body using a compound including an α,β-unsaturated carbonyl group and an acedan (2-acyl-6-dimethyl-amino-naphthalene) fluorescent material; to an imaging method of hydrogen sulfide in cells using the same; and to a manufacturing method of the fluorescent probe. More specifically, in the fluorescent probe of the present invention, the α,β-unsaturated carbonyl group of the compound selectively binds to hydrogen sulfide, inducing an increase in fluorescence of the acedan fluorescent material. The fluorescent probe according to the present invention can be conveniently synthesized, enables two-photon excitation, and corresponds to a small-molecule probe having stability and low toxicity in the body. In addition, the fluorescent probe according to the present invention can exhibit a fluorescent change by selectively reacting with hydrogen sulfide, thereby imaging the distribution of hydrogen sulfide in cells or tissues, and thus can be useful for a composition for imaging and an imaging method.
