We have investigated the impact of the functionalization and the chemical nature of counterions on the p-dimer dications formation in two end-capped heptathienoacenes. Radical cations of an a-substituted heptathienoacene with tris(isopropyl)silyl groups do not p-dimerize, while those of an a,b-substituted heptathienoacene with four n-decyl side chains show a high propensity toward p-dimerization, increased by PF6- counterions.

Abstract
We have investigated the impact of the functionalization and the chemical nature of counterions on the p-dimer dications formation in two end-capped heptathienoacenes. Radical cations of an a-substituted heptathienoacene with tris(isopropyl)silyl groups do not p-dimerize, while those of an a,b-substituted heptathienoacene with four n-decyl side chains show a high propensity toward p-dimerization, increased by PF6- counterions.File in questo prodotto:
