Utilizing Perylene in New Organic Donor–Acceptor Materials: Highlighting the Synthesis, Structure and Physical Properties of Perylene-pDNB and Perylene-TCNP

Abstract

In this communication, we present the syntheses, structure, infrared (IR) spectroscopic, and electronic transport properties for two new Perylene-containing donor-acceptor complexes, Perylene-pDNB (1) and Perylene-TCNP (2). The 2:1 complex with pDNB, complex 1, crystallizes in the triclinic space group P " 1 with cell dimensions a = 7.7488(12) Å , b = 9.7125(15) Å , c = 10.6864(17) Å , a = 80.829(7)°, b = 84.893 (7)°and c = 89.495(6)°, while complex 2, the 1:1 complex with TCNP, crystallizes in the orthorhombic space group Cmca with a = 18.264(4) Å , b = 7.405(2) Å and c = 14.674(3) Å . Structural features of the constituent donor and acceptor molecules were compared to those for the free components and, when coupled with IR spectroscopic measurements, suggested that both complexes contained neutral components. This conclusion was further supported by electronic transport measurements that revealed both complexes to be insulators. Graphical Abstract Herein we present the structure and both the IR spectroscopic and transport properties for new

Structure-dependent optoelectronic properties of perylene, di-indenoperylene (DIP) isolated molecule and DIP molecular crystal

“…It reveals that the energy required for an electron to jump from conduction to valence band is relatively small. It was proved that perylene is one of the donors known due to its highly-conducting organic crystal characteristic [ 29 ]. The minimum valence band and maximum conduction band were shown to be direct in nature along the Γ symmetry point as displayed in Fig.…”

“…Perylene is one of the small model compounds that have been widely used in organic photoelectric and photoconductive fields [ 11 ]. The potential implementations using perylene derivatives are the recognition of the practical use of perylene, which comparable to inorganic compounds [ 29 , 32 ]. Its polycyclic hydrocarbon constructed with the conjunction of single and double bonds proposed the presence of high charges population.…”
