Regularities of reversible radical dissociation in liquid crystals

The effect of liquid-crystalline ordering of alkylcyanobiphenyls on the thermodynamic parameters of reversible dissociation of the dimeric 2,2′-bis[2-(p-dimethylaminophenyl)indane-1,3-dione] to the 2-(p-dimethylaminophenyl)indane-1,3-diyl radicals was found. The angular dependence of the ESR spectra of the radicals in the smectic mesophase is related to their orientation along the liquid crystal director.

The influence of liquid crystal ordering on reversible radical dissociation

The influence of liquid crystal ordering in nematic, smectic and Isotropic phases on thermodynamic parameters of a reversible thermal dissociation of dimeric 2,2-bis[2-(p-dimethylaminophenyl)indan-1,3-dione] into two stables 2-(p-dimethylaminophenyl)indan-l,3-dione-2-yl radicals was investigated.

2-Phenylindanedionyl radicals 5a, their p- and o-monosubstituted derivatives and related compounds 5b-h recombine by C-C bond formation giving 6a-h.In contrast, o-substituted derivatives 5i-k and the 2-tert-butylindanedionyl radicals 5l react to give the

INFLUENCE OF ONIUM SUBSTITUENT IN PHTHALOYL RING ON THERMODYNAMIC PARAMETERS OF EQUILIBRIUM BETWEEN DIMER AND FREE RADICALS OF 2-(4-DIMETHYLAMINOPHENYL)-1,3-INDANDIONES

2,2'-Bis diperchlorate and 2,2'-bis diperchlorate have very definite thermochromic and mechanochromic properties, owing to reversible dissociation into free radicals.The rupture energy of the central bond C2-C2' in 5-substituted 2,2'-bis in acetonitrile is 63-75 kJ/mole; in the dimer with the bulky 5-(2,4,6-triphenylpyridinium) substituent, the rupture energy is 51 kJ/mole.The equilibrium constants follow the Hammett equation (? = 1.53, acetonitrile, 293 K).Radicals with onium substituents are thermodynamically the most stable of the arylindandionyl radicals that are thus far known, owing to the significant contribution of electrostatic interactions.
