Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 63295-48-7, is researched, SMILESS is O=S(C(F)(F)F)([O-])=O.O=S(C(F)(F)F)([O-])=O.O=S(C(F)(F)F)([O-])=O.[Fe+3], Molecular C3F9FeO9S3Preprint, arXiv.org, e-Print Archive, Physics called Mildly-doped polythiophene with triflates for molecular recognition, Author is Boujnah, Aicha; Boubaker, Aimen; Kalboussi, Adel; Lmimouni, Kamal; Pecqueur, Sebastien, the main research direction is polythiophene iron bismuth triflate mol recognition dipole moment electrophilicity.Reference of Iron(III) trifluoromethanesulfonate.
Organic semiconductors have enough mol. versatility to feature chemo-specific elec. sensitivity to large families of chem. substituents via different intermol. bonding modes. This study demonstrates that one single conducting polymer can be tuned to either discriminate water-, ethanol- or acetone-vapors, on demand, by changing the nature of its dopant. Seven triflate salts differ from mild to strong p-dopant on poly(3-hexylthiophene) sensing micro-arrays. Each material shows a pattern of conductance modulation for the polymer which is reversible, reproducible, and distinctive of other gas exposures. Based on principal component anal., an array doped with only two different triflates can be trained to reliably discriminate gases, which re-motivates using conducting polymers as a class of materials for integrated electronic noses. More importantly, this method points out the existence of tripartite donor-acceptor charge-transfer complexes responsible for chemospecific mol. sensing. By showing that mol. acceptors can have duality to p-dope semiconductors and to coordinate donor gases, such behavior can be used to understand the role of frontier orbital overlapping in organic semiconductors, the formation of charge-transfer complexes via Lewis acid-base adducts in mol. semiconductors.
