Abstract
The synthesis and supramolecular organization of a phthalocyanine 3 functionalized with a melamine moiety is described. 3 self-assembles in solution to form dimeric species-driven by double hydrogen-bonding between the aromatic amine functionality that is directly attached to the phthalocyanine ring and the melamine pyridinic nitrogens. In the presence of perylenediimide 2, endowed with a complementary tritopic functionality, electron donor-acceptor assembly Pc-PDI (3)·2 is spontaneously formed. (3)· 2 consists of two phthalocyanines of type 3 and a perylenediimide 2, connected via triple hydrogen bonding between the melamine and the complementary unsubstituted imido functions. Electronic interactions between 2 and 3 in (3)·2 give rise, upon selective photoexcitation of 2, to an intramolecular electron transfer, affording a several nanosecond lived PDI /HPc species, while photoexcitation of 3 is only followed by an ordinary intersystem crossing. © 2013 The Royal Society of Chemistry.
