Ultrafast processes and excited state dynamics in conjugated polymers [PDF]
The photophysics of a number of conjugated polymers used in organic display applications has been studied using ultrafast techniques. An updated method for measuring the intersystem crossing rate was developed.

Tailing miniSOG: Structural Bases of the Complex Photophysics of a Flavin-Binding Singlet Oxygen Photosensitizing Protein [PDF]
We have elucidated the molecular mechanism by which the photosensitizing protein miniSOG, initially a poor singlet oxygen generator, becomes an efficient singlet oxygen generator after prolonged blue-light irradiation and a useful tool in correlative ...

Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Experimental and theoretical study of centrifugal flow singlet oxygen generator
We designed and realized a novel centrifugal flow Singlet oxygen generator (CFSOG) that was originally proposed by Emanuel [Proc. SPIE 5448 (2004) 233].

Understanding and controlling the efficiency of Au24M(SR)18 nanoclusters as singlet-oxygen photosensitizers [PDF]
Singlet oxygen, 1O2, can be generated by molecules that upon photoexcitation enable the 3O2 → 1O2 transition. We used a series of atomically precise Au24M(SR)18 clusters, with different R groups and doping metal atoms M.

Illuminating Olympicenes: Insights Into Anti‐Kasha Photophysics in Polycyclic Aromatic Hydrocarbons
Compact olympicene‐based chromophores reveal unexpectedly rich excited‐state behavior, including dual fluorescence, excitation‐dependent emission, and anti‐Kasha‐type emission. Tunable locally excited and intramolecular charge‐transfer states emerge from subtle structural changes, expanding the design rules for polycyclic aromatic chromophores and ...

High Fatigue‐Resistant Photoswitches Based on iridium(III)‐DTE Systems
Coordination to iridium(III) enhances fatigue resistance over multiple photoswitching cycles in diarylethenes. This metal coordination modulates photoresponse relative to the free ligands under identical irradiation conditions, opening new avenues for practical applications.'' ABSTRACT A series of four differently substituted nonsymmetrical ...

“Dark” Singlet Oxygen Made Easy [PDF]
An operationally simple continuous flow generator of ‘dark’ singlet oxygen has been developed. The singlet oxygen was efficiently reacted with several chemical traps to give the corresponding oxygenated products in high yields.

Quadrupolar, centrosymmetric 1,4‐dihydropyrrolo[3,2‐b]pyrroles (DHPP) possessing two five‐membered rings and highly polarized architecture are not emissive, but they are good photosensitizers in two‐photon induced polymerization. ABSTRACT A series of ladder‐type, highly polarized functional dyes possessing 1,4‐dihydropyrrolo[3,2‐b]pyrrole (DHPP ...

Two previously uncharacterized heterocyclic imines, 3‐iminooxetane and 3‐oxazoline, are generated simultaneously by irradiation of 3‐azidooxetane under matrix isolation conditions. The infrared spectra provide reference data for future gas‐phase studies and may facilitate their search in the interstellar medium.
