Hexa-peri-hexabenzocoronene, substituted

PMl-substituted hexa-peri-hexabenzocoronene (HBC) 35 was designed as model compound for intermolecular energy and electron transfer studies because of its Dgh symmetry, electronic and self-assembling properties [33-35]. The multichromophore (HBC-6PM1) 35 has six PMl chromophores attached to HBC via a 3 -dodecyl-4, 5, 6 -triphenyl-1,l 2, l"-terphenyl spacer unit (Scheme 8). HBC-6PM1 35 was obtained by Diels-Alder reaction of hexa-[4-(tetradec-l-yn-l-yl)phenyl]-HBC 34 [36] and well-established building block PMI-decorated Cp 29 (as discussed above) in diphenyl ether at 250°C in 58% yield [33-35]. Indeed, electronic excitation of the HBC core of this molecule resulted in efficient energy transfer to the PMl shell [37, 38].
