  2. INTRODUCCIÓN 1. Introduction ANTHRAQUINONES Effects (highconcentration) Properties Uses Pigments Fibers Paper Semiconductors Antiviral Antibacterial Antiparasitic Insecticidal Fungicidal Antimalarial Anticancer Toxic Mutagenic Carcinogenic

  6. INTRODUCCIÓN 3. Conclusions Anthraquinonederivatives show a modulation of theirdeprotonation and coordinationprocessabilities as a function of thechemicalgroupattached. Distinctivechromo-fluorogenicbehavioursin thepresence of acetonitrilesolutions are observedwithanions. The F-, whichis a verybasicanion, induce a deprotonationprocess, whereastheAcO- and H2PO4- display a poorerability.
