Investigation of micelles, microemulsions, and phospholipid bilayers with the pyridinium N-phenolbetaine et(30), a polarity probe for aqueous interfaces
The phenolbetaine et(30), a well-known internal probe of solvent polarity, is used to characterize the polarity of its environment in micelles, microemulsions, and phospholipid bilayers. The probeExpand

Single dibenzoterrylene molecules in an anthracene crystal: main insertion sites.
TLDR
From simulated annealing, the molecular conformations in the most stable insertion sites and the orientations of the transition dipole moments are derived and an unambiguous structures for the two principal spectroscopic sites are proposed. Expand
Single molecule lines and spectral hole burning of terrylene in different matrices
We observe fluorescence excitation lines of single terrylene molecules in three new polymer matrices (polyvinylbutyral, polymethylmethacrylate, and polystyrene) and in two crystals, n‐hexadecaneExpand
Single organic molecules for photonic quantum technologies
TLDR
It is shown that quantum emitters based on single molecules hold promise to play a key role in the development of quantum science and technologies and in single-molecule sensing and quantum-sensing applications. Expand
12-hydroxy-1-azaperylene-limiting case of the ESIPT system: enol-keto tautomerization in S0 and S1 states.
TLDR
Observation of absorption and fluorescence of both tautomeric forms and lack of large Stokes shift offluorescence of the keto form classify HAP as the limiting case of the excited-state intramolecular proton transfer system. Expand
Symmetry Breaking in Pyrrolo[3,2-b]pyrroles: Synthesis, Solvatofluorochromism and Two-photon Absorption.
TLDR
It is observed that for compounds with a larger dihedral angle, the fluorescence quantum yield decreased quickly when exposed to even moderately polar solvents, and some small symmetry breaking may be possible in the ground state, even before major symmetry breaking occurs in the excited state. Expand
Vertically π-expanded coumarin--synthesis via the Scholl reaction and photophysical properties.
TLDR
The strategic placement of naphthalene at the 4-position of coumarin allowed us to fuse these two moieties via aromatic dehydrogenation under Scholl conditions and the intriguing optical properties of this π-expanded Coumarin are discussed on the basis of quantum chemical calculations. Expand
Single dibenzoterrylene molecules in an anthracene crystal: spectroscopy and photophysics.
TLDR
Single dibenzoterrylene molecules in an anthracene single crystal at 1.4 K in two insertion sites at 785.1 and 794.3 nm are studied for high-resolution spectroscopy and nanoscale probing at cryogenic temperatures. Expand
Single-molecule photophysics, from cryogenic to ambient conditions.
TLDR
The central role of the triplet state in limiting the number of useful host-guest systems is discussed, notably a new channel, intermolecular intersystem crossing, and the mechanisms of spectral diffusion and dephasing that they have revealed. Expand
