{"abstract":"A Rh3+ complex 4 derived from 4-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol 3 was prepared at room temperature. 3 was stirred with pentamethylcyclopentadienlyrhodium chloride dimer for 30 minutes which resulted yellow precipitates which were washed with methanol, redissolved in acetone and purified chromatographically with ethanol. Phenanthroline-derived 3 was reacted with (3-chloropropyl)trimethoxysilane to obtain an alkylated compound 5. Silica particles were functionalized by reacting with 5 at 70 oC in DMF for 6 h. Functionalized silica particles can be used for removal of different metals from aqueous and organic solutions and due to their bigger size can be easily filtered.","abstract_source":"original","authors":["Mehmet Ali Özler","Said Nadeem"],"date":"2015","doi":null,"id":17,"issue":1,"journal":{"issn":"2651-4338","name":"Journal of Ongoing Chemical Research"},"pdf_sha256":"7ca76111f870c0e0c176b8d7db8b4208d0e394c3f3e2df82c8310de80961dd0f","schema":"scimatic-article/1","title":"SYNTHESIS OF NOVEL NAKED-EYE Fe3+ CHEMOSENSING SILICA PARTICLES AND Rh+3 COMPLEX BASED ON 4-(1H-IMIDAZO[4,5-f][1,10]PHENANTHROLINE-2YLPHENOL","volume":2}
1. The record, from the token's own metadata:
printf '%s' "$(curl -s https://scimatic.org/nft/articles/17.json | jq -r .canonical_record)" | sha256sum
2. The hash stored on chain (contentHash(17)):

-d '{"jsonrpc":"2.0","id":1,"method":"eth_call","params":[{"to":"0x0E596B4bb924937aA35D9b342A90347ed6F05eF8","data":"0xf3e0c2900000000000000000000000000000000000000000000000000000000000000011"},"latest"]}'
The two must be equal (the second with a 0x in front).
