Micelle Stabilized Room Temperature Phosphorescence
1982Micelle stabilized room temperature phosphorescence (MS-RTP) is reported for a representative variety of functionally-substituted aromatic compounds dissolved in aqueous solutions of sodium lauryl sulfate detergent containing 30% thallium(I) counter-ions.

Ultrahigh Supramolecular Cascaded Room‐Temperature Phosphorescence Capturing System
Angewandte Chemie International Edition, 2021AbstractAn ultrahigh supramolecular cascaded phosphorescence‐capturing aggregate was constructed by multivalent co‐assembly of cucurbit[7]uril (CB[7]) and amphipathic sulfonatocalix[4]arene (SC4AD). The initial dibromophthalimide derivative (G) generated a weak phosphorescent emission at 505 nm by host–guest interaction with CB[7], which further ...

Room Temperature Phosphorescent (RTP) N‐Acetylphenothiazines
ChemPhotoChem, 2020AbstractHerein we disclose a series of purely organic molecules (1–4) with a donor‐acceptor architecture (phenothiazine donor (D) and the acyl acceptor (A)) exhibiting room temperature dual phosphorescence (RTDP) characteristics. Detailed computational and photophysical studies revealed that the dual RTP bands with different wavelengths and lifetimes ...

Room temperature phosphorescence optosensor for anthracyclines
The Analyst, 1998A flow-through optosensor for anthracyclines based on the anthracycline–europium chelate room temperature phosphorescence energy transfer is proposed. The sensor was developed in conjunction with a flow injection analysis system and is based on the transient immobilization on a non-ionic resin (packed in a flow-through cell) of the anthracycline ...

Lifetime Spectra for Room-Temperature Phosphorescence
Applied Spectroscopy, 1989A large number of articles on the subject of Room Temperature Phosphorescence (RTP) on solid substrates have recently appeared in the literature, confirming the fact that multiple lifetimes are involved for the analyte. This is not an unexpected observation, considering the heterogeneity of the filter paper substrate employed and the large number of ...

Room Temperature Phosphorescence Optosensor for Terbium
Analytical Letters, 1996Abstract A solid surface room temperature phosphorescence optosensing method has been developed for the determination of terbium(III) based on the adsorption of its binary complex with 1,4-bis (l'-phenyl-3′-methyl-5′-pyrazolone-4′-) butanedione-(1,4) (BPMPBD) onto the hydrogen form of a strong cation exchange resin packed in a flow cell in an aqueous ...

Room temperature phosphorescence optosensor for tetracyclines
Analytica Chimica Acta, 1993Abstract A flow-through optosensor for tetracyclines based on the tetracycline-europium chelate room temperature phosphorescence energy transfer is proposed. The sensor is developed in conjunction with a flow-injection analysis system and is based on the transient immobilization on a non-ionic resin (packed in a flow-through cell) of the tetracycline-

Room-Temperature Phosphorescence of Impure Fluorene
Analytical Letters, 1990Abstract Impurities in commercial fluorene were detected by thin-layer chromatography and identified by room-temperature phosphorimetry (RTP). Acenaphthene content was analyzed by the standard addition method by using normal RTP measurement procedures with T1(I) as the heavy atom.

Room temperature phosphorescence optosensing for gadolinium
Mikrochimica Acta, 1997An optosensing method for gadolinium based on the room-temperature phosphorescence behavior in aqueous solution induced by the transient adsorption of the complex formed by 1,4-bis (1′-phenyl-3′-methyl-5′-pyrazolone-4′-)butanedione (1,4) with Gd (III) on the chelating resin Chelex 100 (packed in a flow cell) is proposed.
