Abstract

The first example of dinaphtho[2,3-b;2’,3’-d]tellurophene (1d) has been synthesized by the condensation of tellurium with 3,3’-dilithio-2,2’-binaphthalene. Single crystal X-ray analysis of 1d revealed that naphthalene and tellurophene rings are almost coplanar. A linear relationship (R2 = 0.971) between the atomic radius of Group 16 elements and the HOMO-LUMO gap energies of 1a–d was found by density functional theory (DFT) calculations.
