Properties of the surfactant—calix[4]resorcinol binary system studied using spectral and fluorescent probes

Turn-on fluorescence of ruthenium pyrene complexes in response to bovine serum albumin

“…20,21 Due to these properties, pyrene is a sensitive fluorescent probe widely used for characterization of different micro-heterogeneous systems. [22][23][24][25][26][27][28] In spite of their potential carcinogenic properties, substituted pyrenes and their organometallic complexes may serve as anti-cancer agents. [29][30][31] Photodynamic therapy is another avenue for the application of pyrene compounds although their non-favourable excitation wavelength (350-400 nm) is far too short for efficient PDT due to low tissue permeability at these wavelengths, as wavelengths of >600 nm would be required.…”

Novel pyrene-calix[4]arene derivatives as highly sensitive sensors for nucleotides, DNA and RNA

“…19,20 Due to these properties, pyrene is a sensitive uorescent probe widely used for the characterization of different micro-heterogeneous systems. [21][22][23][24][25][26][27] In a design of uorescent sensors, an interesting approach is to attach two aromatic uorophores close enough so that the electronic excitation of one ring can cause an enhanced interaction of its neighbour, 28 leading to an excited-state dimer or excimer. 29 In particular, calix [4]arene derivatives bearing two highly p-delocalized planar systems such as pyrenes, display an efficient excimer signal due to the intra-or intermolecular p-p interactions between the two pyrenes, and this excimer emission can be perturbed in presence of guest ions/molecules.…”
