    • The inventive method for optically measuring a sample consists in temporarily repeatedly transmitting an electromagnetic signal (2) to the sample in such a way that a substance contained in the sample is transferred from a first electronic state (1) into a second electronic state (3), wherein at least one part of said substance in the second state (3) emits photons which are used for carrying out the optical measurement of the sample, the signal (2) is transmitted to the same sample area at a certain repetition interval and said repetition interval of the signal (2) is adjusted with a lifetime of the second state (3) of the substance having an order of magnitude of 1 ns on a value of at least 0.1 μs which is optimized with respect to photon yield from the substance.

    • The invention relates to novel and improved photostable rhodamine dyes of the general structural formulae I or II and their uses as fluorescent markers, e.g. for immunostainings and spectroscopic and microscopic applications, in particular in conventional and stimulated emission depletion (STED) microscopy and fluorescence correlation spectroscopy. The partially deuterated analogues are useful as molecular mass distribution tags in mass spectroscopic applications, wherein R1=an unsubstituted or substituted alkyl group, including a cycloalkyl group, or heterocycloalkyl group; R2=H, an unsubstituted or substituted alkyl group, including a cycloalkyl group, or heterocycloalkyl group, or an unsubstituted or substituted aryl group or heteroaryl group, or any combination of such groups; X=CH2, C═O, C═NORa, C═NNRaNRb, CH(ORa), O, S, SO, SO2, or any other derivatives of these groups, with Ra and Rb independently being H or an organic residue, in particular an unsubstituted or substituted (cyclo)alkyl group or heterocycloalkyl group, an unsubstituted or substituted aryl group or heteroaryl group; Z=a negatively charged group with 1, 2, 3, 4 or 5 charges per anion.

    • For the high spatial resolution imaging of a structure of interest in a specimen, a substance is selected from a group of substances which have a fluorescent first state and a nonfluorescent second state; which can be converted fractionally from their first state into their second state by light which excites them into fluorescence, and which return from their second state into their first state; the specimen's structure of interest is imaged onto a sensor array, a spatial resolution limit of the imaging being greater (i.e. worse) than an average spacing between closest neighboring molecules of the substance in the specimen; the specimen is exposed to light in a region which has dimensions larger than the spatial resolution limit, fractions of the substance alternately being excited by the light to emit fluorescent light and converted into their second state, and at least 10% of the molecules of the substance that are respectively in the first state lying at a distance from their closest neighboring molecules in the first state which is greater than the spatial resolution limit; and the fluorescent light, which is spontaneously emitted by the substance from the region, is registered in a plurality of images recorded by the sensor array during continued exposure of the specimen to the light.
