General description

1,4-Bis(5-phenyl-2-oxazolyl) benzene, also known as POPOP, is a well-known scintillation luminophore. It is an efficient fluorescent organic compound with high stokes shift. The POPOP dye is photostable in polar protic and polar aprotic solvents. The resulting photochemical quantum yield and the photodecomposition rate depend on the solvent′s electron affinity.

Application

1,4-Bis(5-phenyl-2-oxazolyl) benzene or POPOP is widely used to detect radioactivity by scintillation counting.

Features and Benefits

1,4-Bis(5-phenyl-2-oxazolyl) benzene or POPOP has the following advantages:

High fluorescence quantum yield.
High molar absorptivity.
Large Stokes Shift.
High Photostability in most organic solvents.

Biochemistry, 27(17), 6203-6208 (1988-08-23)

Measurements of homogeneous and heterogeneous fluorescence intensity decays using a hybrid time-correlated single photon counting/multifrequency phase fluorometer are reported. A trio of fluorophores exhibiting a range of decay profiles was selected. p-Terphenyl, 1,4-bis[2-(4-methyl-5-phenyloxazolyl)]benzene [(Me)2POPOP], and p-bis[2-(5-phenyloxazolyl)]benzene (POPOP), commonly used reference

Upper electron-excited states in bioluminescence: experimental indication.

N S Kudryasheva et al.

Luminescence : the journal of biological and chemical luminescence, 16(3), 243-246 (2001-06-16)

The involvement of upper electron-excited states in bacterial bioluminescence process was studied with excitation energy-accepting molecules. The fluorescent aromatic compounds, anthracene and 1.4-bis(5-phenyloxazol-2-yl)benzene, were chosen. Energies of their lowest excited singlet states are higher than the energy of the analogous

Covalent immobilization of glucose oxidase onto poly(styrene-co-glycidyl methacrylate) monodisperse fluorescent microspheres synthesized by dispersion polymerization.

Xiaohui Hou et al.

Analytical biochemistry, 368(1), 100-110 (2007-06-15)

In this study, micron-sized poly(styrene-co-glycidyl methacrylate) (PSt-GMA) fluorescent microspheres of 5.1microm in diameter were synthesized via dispersion polymerization of styrene and glycidyl methacrylate in the presence of 1,4-bis(5-phenyloxazol-2-yl) benzene (POPOP), which provided surface functional groups for covalent immobilization of enzymes.
