The photobehaviour of four aza-analogues of EE-distyrylbenzene bearing the heteroatom in the two side rings [1,4-di-(2-pyridylethenyl)benzene] or in the central ring [2,5-di-(phenylethenyl)pyridine, 2,6-di(phenylethenyl)pyridine and the corresponding

This paper describes the results obtained in the study of the photobehaviour of heteroanalogs of stilbene bearing an oxazole ring. The competitive relaxation processes (fluorescence, isomerization and cyclization) of the excited states of n-styryloxa
This work follows an earlier one where some sydnone derivatives, interesting for their biological and biomedical applications, were synthesized and the effect of substituents on their photoreactivity was studied in irradiation conditions of high inte

Two nitro-substituted 1,4-distyrylbenzene-like compounds have been investigated using stationary and time-resolved (ns/fs) spectrometric techniques as a function of solvent polarity. In the two compounds the central benzene ring is substituted with a
The effect of protonation on the excited state properties of the three positional isomers of E -5-[2-(pyrid- n -yl)ethenyl]oxazole’s ( n -PyEt-5Ox with n = 2, 3 and 4) was studied in buffered water by spectrophotometric, fluorimetric and chromatogr

This paper describes the results obtained in the study of the photobehaviour of heteroanalogs of stilbene bearing oxazole and pyridine rings at the opposite sides of the ethene moiety. The effect of the positional isomerism of the n -pyridyl group (

The photobehavior of two 1,4-distyrylbenzene analogues where the central benzene ring is asymmetrically substituted with a pyrid-4-ylethenyl group at one side and thien-2-ylethenyl or a p-nitrostyryl group at the other side, has been studied in two s
