Aromatic carboxylates of the rare earths are known for highly efficient luminescence, thus holding the promise of applicability in optical devices, but may be problematic to apply as such due to their structure, which is polymeric in nature.

THE PHOTOPHYSICS OF p‐AMINOBENZOIC ACID
Photochemistry and Photobiology, 1995Abstract— The lowest‐lying allowed UV transition in p‐aminobenzoic acid (PABA) is assigned Γ→1La based on quantitative absorption and fluorescence studies, as well as semiempirical PM3 multielec‐tron configuration interaction calculations. The oscillator strengths, fluorescence quantum efficiencies and lifetimes are reported for PABA in several polar,

Publisher Summary p -Aminobenzoate synthase catalyzes the first specific reaction in the folic acid biosynthetic pathway, that is, the formation of p -aminobenzoate (PABA) from chorismate and glutamine. PABA is also a likely intermediate in the biosynthesis of candicidin by Streptomyces griseus.

Boron trifluoride ethyl ether as an effective catalyst in the synthesis of alkyl p-aminobenzoates.
Journal of Pharmacy and Science, 1969Commercial boron trifluoride ethyl ether functions as an effective catalyst in the synthesis of a number of alkyl esters of p-aminobenzoic acid. Unlike earlier procedures, the present method offers a convenient single step reaction and does not call for ...

Dipole moments of some aminobenzoates
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19731. The dipole moments of eight molecular compounds, formed by various aliphatic amine derivatives with benzcic acid and its nitro derivatives, were measured. 2. All of the studied compounds are dimeric in nonpolar solvents. 3. A theory was expressed regarding the structure of the studied complexes. 4.

Crystal structures of cyclomaltoheptaose (beta-cyclodextrin) complexes with p-aminobenzoic acid and o-aminobenzoic acid have been determined by single-crystal X-ray diffraction. The space group of the beta-cyclodextrin-p-aminobenzoic acid complex is P2(1) with a host:guest stoichiometry of 1:1, and that of the beta-cyclodextrin-o-aminobenzoic acid ...
