The Influence of Chromophore Structure on Intermolecular Interactions. A Study of Selected Rhodamines in Polar Protic and Aprotic Solvents [PDF]

, 2020
We have studied the linear optical response and orientational relaxation dynamics of a family of rhodamine dyes in which there is substantial variation in the chromophore structure. For these chromophores, the identity of a substituent at the center ring

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Investigations of the reactivity of pyridine carboxylic acids with diazodiphenylmethane in protic and aprotic solvents.

, 2005
Rate constants for the reaction of diazodiphenylmethane with isomeric pyridine carboxylic acids were determined in chosen protic and aprotic solvents at 30 °C, using the well known UV spectrophotometric method.

Cellulose swelling by aprotic and protic solvents: What are the similarities and differences?

, 2008
The swelling of microcrystalline, native and mercerized cotton and eucalyptus celluloses by 16 aprotic solvents was investigated. The number of moles of solvent/anhydroglucose unit, nSw, correlates well with solvent molar volume, basicity and dipolarity ...

Photoinduced Electron Transfer (PET) as Key to Accelerate the Cycloreversion Reaction of Arylquadricyclanes

Chemistry – A European Journal, EarlyView.
It is demonstrated that the photoinduced cycloreversion of a methoxynaphthylquadricyclane in the presence of suitable photocatalysts gives quantitatively the corresponding norbornadiene. As this photochromic norbornadiene‐quadricyclane cycle has favorable properties for light energy conversion, this method provides a useful tool for the targeted ...
