Abstract: A series of negative T-type nitrile-rich photochromes containing a hydroxytricyanopyrrole acceptor was synthesized. It was shown that thermal stability of the photoinduced form could be tuned by the replacement of a substituent in para-position to… read more here.

Abstract: Representatives of negative photochromes containing a nitro-substituted 2-vinylphenolic fragment and a tricyanofuran (TCF) acceptor were synthesized. An efficient “turn-off” fluorescence photoswitching with full reversibility was shown for these compounds due to the negative photochromic transformation… read more here.
