Twisted pyrene-fused azaacenes.
An approach for introducing twists in pyrene-fused azaacenes is reported. Depending on the volume and the rigidity of the silyl groups, different-sized twist angles, which oscillate between 4° and 24°, are induced along the longitudinal conjugated backbone.
متن کاملAn electron-conducting pyrene-fused phenazinothiadiazole.
A pyrene-fused phenazinothiadiazole that shows electron mobilities (μe = 0.016 cm(2) V(-1) s(-1)) two orders of magnitude higher than those reported for pyrene-fused pyrazaacenes is described.
متن کامل2,6-Dibenzyl-1,2,3,5,6,7-hexahydro-2,4,6,8-tetraaza-s-indacene and 2,6-bis(4-methoxybenzyl)-1,2,3,5,6,7-hexahydro-2,4,6,8-tetraaza-s-indacene.
The title compounds, C22H22N4 and C24H26N4O2 [alternative names: 2,6-dibenzyl-2,3,6,7-tetrahydro-1H,5H-dipyrrolo[3,4-b; 3',4'-e]pyrazine and 2,6-bis(4-methoxybenzyl)-2,3,6,7-tetrahydro-1H,5H-dipyrolo[3,4-b;3',4'-e]pyrazine], two 1,2,3,5,6,7-hexahydro-2,4,6,8-tetraaza-s-indacene derivatives, are both centrosymmetric and have similar S-shaped structures. In the former, there are two independent m...
متن کاملA tetraalkylated pyrene building block for the synthesis of pyrene-fused azaacenes with enhanced solubility.
The synthesis and characterisation of a soluble pyrene-fused tetraazaoctacene derivative has been achieved by developing a key pyrene-based building block with four solubilising groups.
متن کاملStability and aromaticity of the cyclopenta-fused pyrene congeners.
The aromaticity of all possible cyclopenta-fused pyrene congeners has been investigated at various levels of theory. On the basis of the calculated resonance energies and magnetic properties (delta(1)H data, magnetic susceptibility anisotropies, and NICS values), the overall aromaticity of these compounds is found to decrease gradually with increasing number of externally fused five-membered ri...
