Struktury molekularne wybranych heterocyklicznych analogów fluorenu o potencjalnych właściwościach optoelektronicznych

The molecular structures of five heterocyclic (B, N, O, P, S) fluorene analogues used as organic optoelectronic materials and organic semiconducting materials have been reviewed. These chemical compounds are mainly used for construction of dye-sensitized solar cells, organic field transistors and organic light-emitting diodes. The most common applications in this area are heterocyclic analogues of fluorene containing nitrogen or sulfur atoms in molecular structure. Due to the small energy gap between the HOMO and LUMO molecular orbitals, it can be expected that in the near future molecular systems containing a boron atom will be more widely used in electronics as organic materials.
