environment control energy flow in molecules is a requirement for the efficient design of tailor-made photochemistry. Here, we investigate the tunability of the photochemical and photophysical properties of the retinal-protonated Schiff base chromophore in solution. Replacing the n-butylamine Schiff base normally chosen to mimic the saturated linkage found in nature by aromatic amines results in the reproduction

An air freshening device is provided. The device includes a water-based fragrance emitter including water, a water absorbing polymer and a fragrance composition. The fragrance composition includes from about 3% to about 70% by weight of at least one fragrance ingredient exhibiting a standard equilibrium headspace concentration (HSi0) below about 100 μg/L. The water-based fragrance emitter provides a working signal and an end of life signal upon evaporation. The air freshening device is a warming device.
