| description | A lot of previously unknown derivatives of dithienylperfluorocyclopentene (DTPFCP) were synthesized.
It was shown that 2,2′-dialkylsubstituted DTPFCP'S are phtochromes. The quantum yields of forward
and backward photochemical reactions and spectral parameters of open and cyclic forms of the photochromes
synthesized were measured. An attempt to obtain fluorescing phtochromes by means of introduction
of benzoxazolyl, benzthiazolyl and 1,2,4-oxadiazolyl moieties in 5 and 5′ positions of DTPFCP failed;
these compounds were synthesized but they do not fluoresce. |
