Room Temperature Phosphorescence Driven by Mechanochromism
Chemistry – An Asian JournalAbstract Molecules exhibiting phosphorescence emission, with variation in its emission wavelength or intensity upon external mechanical force, are known as a phosphorescent mechanochromic materials (PMC). This review focuses on the development of organic mechanophosphorescent molecules and their emission in response to a mechanical ...

Room-temperature phosphorescence of manganese-based metal halides
Dalton Transactions, 2021Four manganese-based metal halides of different dimensions with a long lifetime and high luminous efficiency were synthesized by changing organic cations. From 2D to 0D, the luminescence efficiency and RTP lifetime of manganese halides were enhanced.

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.

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 ...

Molecular Persistent Room-Temperature Phosphorescence from Tetraarylaminoboranes
Inorganic Chemistry, 2023Herein, we report the synthesis, molecular structure, and optical features of tetrarylaminoboranes 1 (Mes2B-N(Ph)(C10H7)) and 2 (Mes2B-N(Ph)(C14H9)). In the solution state, 1 shows aggregation-induced emission enhancement and color switching, while 2 displays emission color switching and aggregation-caused quenching. At 77 K, frozen solutions of 1 show

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 ...

Determination of nafcillin by room temperature phosphorescence
Analytica Chimica Acta, 2000Abstract Room-temperature phosphorescence, as a very high selective and sensitive method, was applied to the determination of nafcillin in pharmaceutical preparations. The use of phosphorescence enhancer such as sodium dodecyl sulfate (micellar agent), thallium (I) nitrate (external heavy atom), and sodium sulfite (deoxygenation agent) was studied ...

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 ...
