Calix[n]phenothiazines: Optoelectronic and Structural Properties and Host–Guest Chemistry

“…Examples are calix [4]pyrroles, 4 calix[n]furanes (n ¼ 5-8), 5,6 calix [4]thiophenes, 7 calix[n]triazoles (n ¼ 4-6), 8 calix[n] imidazolium salts (n ¼ 4, 5), 9 calix[n]indoles (n ¼ 3, 4), [10][11][12] and the recently reported calix[n]carbazoles (n ¼ 3, 4). 13,14 Phenothiazine has long been of interest to chemists 15,16 due to its pharmacological and biological activity [15][16][17][18] and its use in dye chemistry, [19][20][21] among others. Phenothiazines are fluorescent and feature a reversible oxidation process, which makes them attractive for applications in organic electronics [22][23][24] and in batteries.…”

A Spectrophotometric Investigation of the Interaction between Antimony (III) and (V)1a,b,c in Hydrochloric Acid Solutions

“…Discussion and Interpretation.-The fact expressed by equation (2) that in concentrated hydrochloric acid the optical density of interaction absorption is proportional to the product of the concentrations of the antimony(III) and (V) implies that the absorbing species is a dimeric complex containing one antimony(III) and one antimony (V) . That is, the equilibrium involved in the formation of the absorbing species is of the type Sb(III)Cl4-+ Sb(V)Cl6-¡¿it Sb2Cl10-( 5) C(Sb2Clio~) = KCmCv (6) rather than the type 2C1-+ Sb(III)Cl4-+ Sb(V)Cl6-¡jzt 2Sb(IV)Cl6- (7) C(Sb(IV)Cl6-) = V K'CmCy (8) The equilibrium equations ( 6) and ( 8) should of course be written with activities instead of concentrations. That equation (2) fits the data so well indicates that in concentrated hydrochloric acid the appropriate activity coefficient product involving the activity coefficients of antimony(III) and (V) and of the dimer are to a good approximation independent of the total antimony concentration even when this is as high as 1.5 F.…”
