Starting from ilimaquinone (1), an hemisynthetic phishing probe (2) was prepared for annotating and matching structurally related natural substances in D. metachromia crude extract network. This strategy allowed characterizing for the first time in Nature the blue zwitterionic quinonoid chromophore. The solvatochromic properties of the latter are reported. specialized chromophores cyanines marine natural dyes molecular networking zwitterions POLYNESIE FRANCAISE TUAMOTU 035 020 Chemistry-a European Journal 23 58 14454-14461 2017 0947-6539 https://www.documentation.ird.fr/hor/fdi:010071281 10.1002/chem.201702336 0947-6539 [F B010071281] https://www.documentation.ird.fr/hor/fdi:010071281 https://www.documentation.ird.fr/intranet/publi/2017/11/010071281.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-12-04 2023-07-11 fdi:010071281 fre
