Stimuli‐Responsive Polymers with Room‐Temperature Phosphorescence
Chemistry – A European Journal, 2022AbstractTaking advantages of the impressing behaviors of room‐temperature phosphorescence (RTP), the explorations in RTP materials are not only limited to efficient emission and ultralong lifetime of phosphorescence. The discovery and creation of stimuli‐responsive properties have become the major pursuit, which will lay a solid foundation for future ...

Supramolecular Purely Organic Room-Temperature Phosphorescence
Accounts of Chemical Research, 2021In recent years, purely organic room-temperature phosphorescence (RTP) has aroused wide concern and promotes the development of the supramolecular phosphorescence. Different from organic crystallization, polymerization, or matrix rigidification, supramolecular strategy mainly takes advantage of the synergy between supramolecular co-assembly and strong ...

Laser Phosphoroscope and Applications to Room-Temperature Phosphorescence
Applied Spectroscopy, 2011A simple phosphoroscope with no moving parts is described. In one scan the total luminescence, the long-lived phosphorescence, and the short-lived fluorescence can be determined. A 50% duty cycle excitation from a diode laser is used to excite the sample, and from the digitized waveform the phosphorescence is extracted from the off period, the total ...

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 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
