Solvatochromic, DFT Insight into Chemical and Physical Parameters of 4-(4-Nitro-phenoxymethyl)-benzo[h]chromen-2-one (NM2BC).
Article in Journal of fluorescence, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The absorption and fluorescence characteristics of coumarin derivative 4-(4-Nitro-phenoxymethyl)-benzo[h]chromen-2-one (NM2BC) are studied at room temperature in pure organic solvents to understand the nature of its electronic transitions and solvent interactions. The study aims to investigate the solvent-dependent photophysical behavior of NM2BC and estimate the electric dipole moments in both the ground and excited states using solvatochromic methods. Additionally, the work seeks to explore the intramolecular charge transfer (ICT) nature in the excited state and assess the chemical reactivity and stability of NM2BC. The effects of solvents on spectral characteristics were examined using solvatochromic techniques, and Density Functional Theory (DFT) at the CAM-B3LYP/6-311 + + G (d, p) level was utilized in conjunction with quantum chemistry calculations and the solvatochromic shift to estimate electric dipole moments in both the ground and excited states. The electronic structure was analyzed using Frontier Molecular Orbital (FMO) analysis. To evaluate reactivity and stability, Global Reactivity Descriptors were calculated using FMOs. To determine the preferred electrophilic and nucleophilic attack sites, Molecular Electrostatic Potential (MEP) analysis was performed. Strong interactions and intramolecular charge delocalization were investigated using Natural Bond Orbital (NBO) analysis.
