Spectrochimica Acta Part A: Molecular Spectroscopy, 1984
Abstract This paper reports the electronic absorption spectrum of 8-hydroxyquinoline in the liquid and vapour states in the region 50 000-28 000 cm −1 and the i.r. absorption spectrum in the region 400–4000 cm −1 in KBr and in the neat liquid.

Tumor-targeted delivery of 8-hydroxyquinoline
International Journal of Radiation Oncology*Biology*Physics, 1991RIF-1 mouse tumors express high levels of beta-glucuronidase activity relative to most normal tissues. The high activity can be exploited for targeting specific drugs preferentially to tumor tissues. In this study we examined the kinetics of 8-hydroxyquinoline (8-OHQ) accumulation in tumor and in several normal tissues resulting from the in vivo ...

Chloromethylation of 8-hydroxyquinoline
Analytica Chimica Acta, 1956Abstract The reaction of formaldehyde on a hydrochloric acid solution of 8-hydroxyquinoline, in the presence of hydrochloric acid gas, gave a chloromethyl derivative which is probably 7-chloromethyl-8-hydroxyquinoline hydrochloride. This compound is readily converted into the 7-hydroxymethyl derivative in alkaline solution.

The spectroscopy, electrochemistry, and electrogenerated chemiluminescence (ECL) of [(q)(qH)Li]x (qH=8-hydroxyquinolinato) and [(Meq)(MeqH)Li]x (MeQH=2-methyl-8-hydroxyquinolinato) have been investigated. In both acetonitrile and aqueous solutions, [(q)(qH)Li]x and [(Meq)(MeqH)Li]x have absorption maxima at 320 and 309 nm, respectively. When excited at

The Journal of Chemical Thermodynamics, 1989
Abstract The standard (po = 0.1 MPa) molar enthalpies of combustion, in oxygen, at 298.15 K, were measured by static bomb calorimetry for three 8-hydroxyquinolines; the vapour pressures of the crystals were measured as functions of temperature by the Knudsen-effusion technique, and the standard molar enthalpies of sublimation, at 298.15 K, were ...

Spectrochimica Acta, 1956
Abstract The infra-red absorption spectra of solid 8-hydroxyquinoline, 2-methyl-8-hydroxyquinoline, 4-methyl-8-hydroxyquinoline, and of a number of metal chelates derived from these reagents, have been studied. In general, the spectra of the metal chelates derived from a given reagent were found to be quite similar.

Spectrochimica Acta Part A: Molecular Spectroscopy, 1975
Abstract The thermodynamic dissociation constants for the deprotonation and dissociation steps of 8-hydroxyquinoline, 5-chloro-8-hydroxyquinoline and 5-nitro-8-hydroxyquinoline in the temperature range 20–60°C have been determined by the spectrophotometric method.

Photodegradation of 8-hydroxyquinoline aluminum
Synthetic Metals, 2001The photodegradation of 8-hydroxyquinoline aluminum (Alq 3 ) films under UV irradiation was studied by means of X-ray photoelectron spectroscopy, nano-second fluorescence spectrophotometer, and photoluminescence spectra. Degradation in photoluminescent properties was significant in an air environment.

[Allergies to 8-hydroxyquinoline derivatives].
Dermatosen in Beruf und Umwelt. Occupation and environment, 1988Evaluation of our standardized test results from 1972 to 1983 indicated Vioform allergies in 1.2% of all cases and Sterosan allergies in 1.1%. Our results are within the spectrum found in the literature for Vioform between 0.3 and 5.1% and for Sterosan between 0.3 and 3.7%.
