By incorporating highly functional inorganic units in organic materials, the creation of advanced materials possessing both advantages of organic components such as designability and good processability and inorganic elements can be expected. However, there are several difficulties in combination with organic and inorganic components due to intrinsic low compatibility between organic and inorganic components. Although organic-inorganic hybrids have been developed, further strategies for material design such as for precise controls of nanostructures in the hybrids are strongly required. To meet these demands, we propose the new concept for material design based on an “element-block” which is defined as a minimum functional unit composed of heteroatoms. In this chapter, the basic idea of an “element-block” and the recent progresses in the development of “element-block materials” are mainly from our recent works. As a representative example, we illustrate the element-blocks involving specific steric structures such as polyhedral oligomeric silsesquioxane (POSS), modified boron dipyrromethenes (BODIPYs) having the cardo boron and [2.2]paracyclophanes as a chiral source and explain material properties originated from these element-blocks. The roles of these element-blocks in the materials are explained.
