Photophysical properties and applications of coordination complexes incorporating pyrene

Pyrene Based Chemosensor for Selective Sensing of Fluoride in Aprotic and Protic Environment

“…Pyrene-containing molecular systems have been studied extensively because they exhibit a distinctive excimer emission. Various pyrene systems capable of showing the metal-induced excimer enhancement or quenching have been reported earlier [11,12]. Taking into account our interest in the development of sensors for anions and inspired by our previous work on the use of hydrazones [13], we report herein the synthesis and characterization of new heteroaromatic conjugated system consisting of pyridyl-N, imine-N and pyrene ring.…”

Synthesis, characterization and photophysical studies of novel pyrene labeled ruthenium (II) trisbipyridine complex cored dendrimers

“…[21][22][23][24][25] The introduction of pyrene moieties in polypyridine ligands for the complexation of ruthenium and other metal centers have been recently reviewed. [26] A special interest for the combination of pyrene with a metal center raised from the fact that the energy level of the 3 MLCT emitting state of Ru(II) bipyridine complex can be tuned to be nearly isoenergetic with respect to the triplet state of pyrene. When this occurs, reversible triplet-triplet energy transfer between the 3 (π-π) and 3 MLCT can be observed.…”

Self-aggregation of the pyrene labeled poly(acrylic acid) in nanoscopically crowded environments

“…Fluorescent materials with multifunctional properties have been obtained using one of the most widespread hydrophobic fluorophore, namely pyrene (Py) [1][2][3][4]. Pyrene-based materials are of major interest to design organic electronic devices such as sensors, light emitting diodes, dye sensitized solar cells or to shed light on the structure of proteins, peptides, lipid membranes, etc.…”
