A Greener Route to Blue: Solid-State Synthesis of Phthalocyanines.
Article in Angewandte Chemie (International ed. in English), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Phthalocyanines are important organic dyes with a broad applicability in optoelectronics, catalysis, sensing and nanomedicine. Currently, phthalocyanines are synthetized in high boiling organic solvents, like dimethylaminoethanol (DMAE), which is a flammable, corrosive, and bioactive substance, miscible with water and harmful to the environment. Here we show a new solid-state approach for the high-yielding synthesis of phthalocyanines, which reduces up to 100-fold the amount of DMAE. Through systematic screening of solid-state reaction parameters, carried out by ball-milling and aging, we reveal the influence of key variables-temperature, presence of a template, and the amount and role of DMAE in the conversion of tBu phthalonitrile to tetra-tBu phthalocyanine. These results set the foundations to synthesize these high-performance dyes through a greener approach, opening the field of solid-state synthesis to a wider family of phthalocyanines.
