Abstract
An efficient copper-catalyzed solvent-free multicomponent reaction for pyridine derivatives, iodonium ylides, and 1,4-quinones is developed via a room-temperature ball milling technique. The reported protocol provides a sustainable synthesis of isoindolo[2,1-a]pyridine/isoquinoline class of molecules in good to excellent yield in a mixer mill (RETSCH MM400) engaging the commercially available copper acetate (Cu(OAc)2) as a catalyst without the use of organic solvents. It tolerates a myriad of electron-rich and electron-deficient functionalities on the pyridine moiety. The scalability of the protocol was illustrated by successfully performing the reaction in the gram scale. The photoluminescence and related cellular study revealed that these can be used as a fluorescent chromophore-based cellular probe. A clean reaction profile and a facile experimental setup that is devoid of anhydrous reaction conditions and toxic organic solvents have established the advantages of this strategy over the reported process.

Spange S, Mayerhöfer TG. The negative solvatochromism of Reichardt`s dye B30 - a complementary study. Chemphyschem 2022; 23:e202200100. [PMID: 35579664 PMCID: PMC9400910 DOI: 10.1002/cphc.202200100] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 05/17/2022] [Indexed: 12/02/2022]
Abstract
The UV/Vis spectra of a hypothetical negative solvatochromic dye in a solvent are theoretically calculated assuming the classical damped harmonic oscillator model and the Lorentz‐Lorenz relation. For the simulations, the oscillator strength of the solvent was varied, while for the solute all oscillator parameters were kept constant. As a result, a simple change of the oscillator strength of the solute can explain the redshift and intensity increase of the UV/Vis band of the solute. Simulated results are compared with measured UV/Vis spectroscopic data of 2,6‐diphenyl‐4‐(2,4,6‐triphenylpyridinium‐1‐yl) phenolate B30 (Reichardt‘s dye) Significant correlations of the absorption energy (1/λmax) with the molar absorption coefficient ϵ as function of solvent polarity are demonstrated for several derivatives of B30. The approach presented is only applicable to negative solvatochromism. Therefore, while the approach is vital to fully understand solvatochromism, it needs to be complemented by other approaches, e. g., to describe the changes of the chemical interactions based on the nature of the solvent, to explain all its various aspects.

Abstract
We report on the absorption, fluorescence, and two-photon excitation spectra of a series of 5-phenylisoindolo[2,1-a]quinoline dyes. Depending on the substituents, we observed increasing two-photon absorption cross sections, with values up to 56 GM@973 nm, which are similar to those of the enhanced green fluorescent protein and fluorescein, common fluorescent chromophores.
