Tetracyanobutadiene functionalized ferrocenyl BODIPY dyes.
Tetracyanobutadiene (TCBD) derivatives of ferrocenyl BODIPYs 2a-2c were designed and synthesized by [2 + 2] cycloaddition-retroelectrocyclization reaction of tetracyanoethylene (TCNE) with meso alkynylated ferrocenyl BODIPYs. The TCBD substituted ferrocenyl BODIPYs were designed in such a way that the distance between the ferrocenyl unit and the TCBD remains constant, whereas the distance betwe...
متن کاملSolvent Effects on the Spectral Properties of the Methine Dyes
Recently, methine dyes have attracted interest for their possible application in display devices [1, 2 ] . A liquid crystal display based on the ability of "guest"' pleochroic dyes to align parallel to the "host" liquid crystal was first described by Heilmeier and Zanoni [3 ] . Since then the basic properties of "guest-host" type liquid crystal display devices and the effects of various paramet...
متن کاملBond alternation, polarizability, and resonance detuning in methine dyes.
We derive structure-property relationships for methine ("Brooker") dyes relating the color of the dye and its symmetric parents to its bond alternation in the ground state and also to the dipole properties associated with its low-lying charge-resonance (or charge-transfer) transition. We calibrate and test these relationships on an array of different protonation states of the green fluorescent ...
متن کاملScope of negative solvatochromism and solvatofluorochromism of merocyanines.
A vinylogous series of highly dipolar merocyanines were designed to study their solvatochromism in a wide range of solvents including low-polarity alkanes. It has been revealed that the lower vinylogues indeed have negative solvatochromism in the full range of solvent polarities starting from n-hexane, while the hexamethinemerocyanine exhibits reversed solvatochromism. With the extreme ranges o...
