## Abstract Spectral and photophysical properties of thioxanthone (9__H__βthioxanthenβ9βone, TX) were determined in a few protic solvents (H~2~O, D~2~O, hexafluoroβ2βpropanol) and compared with those in aprotic solvents. On the basis of the timeβresolved and steadyβstate emission measurements and a

The standard potential, go, of the Tl/Tl' and Tl/Tl'222 electrodes (T1+222 is the cryptate formed between a Tl+ cation and cryptand 222) has been measured in dimethylsulphoxide, N,Ndimethylacetamide, N,N-dimethylformamide, acetonitrile, acetone, sulpholane and propylene carbonate. It has been shown
6-(Triphenylphosphonio-3Π-cyclopentadienyl)-2,3,5-trihalocyclohexa-2,5-diene-1,4-diones (2) are a new class of phosphorus containing dyes that behave as weak bases. Mono-protonation occurs at the cyclopentadiene ring leading to three isomers as assessed by NMR. The kinetics of the protonation were s
