Porphyrins self-organized materials

Actually, porphyrins can themselves constitute nanoreactors, from the molecular square made of four porphyrins coordinated with four rhenium centers, that encapsulate a Mn(lll) porphyrins (catalyst for alkene epoxidation) [2 and references therein] to self-organized porphyrinic materials [13], to multipor-phyrinic cages [14],...

As a result, a wide variety of self-assembled porphyrin structures are highly desirable for practical use, which can be applied to nonlinear optical materials (Collini et al., 2006 Liu et al., 2006 Matsuzaki et al., 2006 Terazima et al., 1997), organic solar cells (Hasobe et al., 2003) and sensor devices ( Fuji et al., 2005 Lucaet al., 2007). 

Control of molecular self-assembly to generate supramolecular architectures that are organized in well-defined geometries is important in various fields of science and technology [ 1,2], As porphyrins and phthalocyanines (Pcs) serve as components of molecular materials that possess imique electronic, magnetic and optical properties [3,4], supramolecular assembly based on them is subject to intense research targets. In this section the basic elements of supramolecules based on porphyrins are described and the creation of op-... 

Herein, we describe recent developments in the use of porphyrins and phthalocyanines in the field of optical and electronic materials, the properties of which are mainly controlled by molecular self-assembly. Photovoltaic cells are currently of broad interest as potential low-cost approaches to solar energy conversion. Large-area electronic devices and solution-processed organic semiconductors based on porphyrins, phthalocyanines, and other molecules could have potentially a huge cost advantage over Si-based devices if conversion efficiency and durability can be improved to the level of Si-solar cells. We are now approaching this goal as shown herein, where supramolecules based on porphyrins and phthalocyanines may play crucial roles.
