By fluorescence and phase properties of a 1-acyl-2-[8-(2-anthroyl)-octanoyl]-sn-glycero-3-phosphocholine probe, the influence of the chromophore on the phase transition of bacteriorhodopsin^lipid vesicles was investigated. It was observed that removal of the chromophore led to the down-shifting of the phase transition temperatures. The temperatures corresponding to the beginning and ending of the gel^liquid phase transition were also influenced. This demonstrated that the liquid phase is reached more easily when the chromophore is bleached. The results indicate that removal of the chromophore alters the protein^lipid interactions. It is suggested that this alteration might be related to the change in the lipid molecular packing. ß

“…Amongst the different characteristics exhibited by these probes, sensitivity to the environment has proven to be a valuable asset for biological applications . Numerous electron donor–acceptor systems have been engineered, as they exhibit strong solvatochromic properties, weak fluorescence in aqueous medium and large fluorescent quantum yield in hydrophobic environments .…”

The nitrobenzofurazan (NBD) moiety has gained tremendous popularity over the last decades due to its fluorogenic nature. Indeed, upon interaction with aliphatic amines, it generates a stable fluorescent adduct, which has been used for protein and lipid labeling. In fact the 4-amino substituted NBD belongs to the broad family of intramolecular charge transfer molecules, with the amino group acting as an electron donor upon photoexcitation, and the nitro group as an electron acceptor. Although the singlet excited state of 4-amino NBD derivatives has been abundantly studied, investigation of its triplet manifold is scarce and even the absence of intersystem crossing for this type of molecules has been suggested. However, intramolecular charge transfer molecules are known to undergo intersystem crossing and high phosphorescence quantum yields have been reported in a nonpolar solvent. In the present paper, we have investigated the photophysical and photochemical properties of N-hexyl-7-nitrobenzo[c][1,2,5]xadiazole-4-amine. We have shown the existence of a triplet state for this molecule in cyclohexane via nanosecond laser flash photolysis. Interestingly, deactivation of the triplet state leads to photoproducts formation, which are only present in the absence of oxygen.

“…Sensing Properties and Mechanism Studies. As mentioned above, Cu 2+ is one of the best-known quenchers which quenches, with high efficiency, the fluorescence emission of most fluorophores in aqueous solution. − , As for the film described in the present work, however, the quenching strongly depends on the chemical nature of the counteranions of Cu 2+ . Figure depicts the plots of I 0 / I against the concentrations of various Cu 2+ salts of different counteranions, where I 0 and I stand for the fluorescence intensity of the film in the absence and presence of Cu 2+ salts, respectively.…”

Spacer Layer Screening Effect: A Novel Fluorescent Film Sensor for Organic Copper(II) Salts

A fluorescent film sensor was prepared by chemical assembly of pyrene on a glass plate surface via a long flexible spacer. It was found that the film is highly selective for some organic Cu2+ salts, such as copper acetate and copper propionate. The presence of inorganic Cu2+ salts and other metal(II) acetates, including Ni2+, Co2+, Pb2+, Cd2+, Zn2+, etc., had little effect upon the sensing behavior of the film for copper acetate or copper propionate. The observation was explained by employing a proposed "two-dimensional solution" model. The quenching by copper acetate of the emission of the film is static in nature due to complexation of the spacers to the metal ions. Furthermore, the response of the film sensor to copper acetate is fully reversible. To the best of our knowledge, this film sensor may be the first one that can differentiate greasy copper salts from inorganic copper salts.
