In this article are described dendritic structures containing photoactive groups at the surface or in the core. The observed supramolecular effects can be attributed to the nature of the photoactive group and their location in the dendritic architect

Metalloporphyrins and phthalocyanines have remarkable electrocatalytic properties, generally associated with the ring coordinated transition metal ion, which can be further improved based on supramolecular approach, by combination with suitable molec

The heteroaggregation behavior between a new class of nonplanar cationic β-octabrominated meso -alkylpyridinium zinc(II)-porphyrins (β-Br 8 (ZnP)) and anionic tetrasulfonated metallophthalocyanines (MTSPc, M = Ni(II) and Cu(II)) has been studied by

The deprotonation of the push-pull molecule 4-hydroxy-4'-nitroazobenzene leads to a substantial variation in the charge distribution over the donor and acceptor moieties in the D-pi-azo-pi-A system. The extra charge stabilizes the excited state, lead

There is great interest in the investigation of heterodimers formed by metalloporphyrins and metallophthalocyanines grafted with oppositely charged substituents, since these systems are models of the photosynthetic special pair and promising unidirec

Two poly(propyleneimine) dendrimers bearing up to 32 photoisomerizable azobenzene groups in the periphery have been used as potential hosts for eosin Y (2‘,4‘,5‘,7‘-tetrabromofluorescein dianion). The all-E azobenzene dendrimers can be revers

We report the synthesis of six new dendrimers built around a [Ru(bpy)3]2+-type core (bpy = 2,2‘-bipyridine) and bearing up to 24 4‘-tert-butylphenyloxy or 48 benzyl units in the periphery. The metallodendrimers were obtained by complexation of ru
