Deciphering the Multifarious Charge-Transport Behaviour of Crystalline Propeller-Shaped Triphenylamine Analogues

A collection of para-substituted propeller-shaped triphenylamine (TPA) derivatives have been computationally investigated for charge-transport characteristics exhibited by the derivatives by using the Marcus–Hush formalism. The various substituents chosen herein, with features that range from electron withdrawing to electron donating in nature, play a key role in defining the reorganisation energy and electronic coupling properties of the TPA derivatives. The TPA moiety is expected to possess weak electronic coupling on the basis of poor orbital overlap upon aggregation, owing to the restriction imposed by the propeller shape of the TPA core. However, the substituent groups attached to the TPA core can significantly dictate the crystal-packing motif of the TPA derivatives, wherein the variety of noncovalent intermolecular interactions subsequently generated drive the packing arrangement and influence electronic coupling between the neighbouring orbitals. Intermolecular interactions in the crystalline architecture of TPA derivatives were probed by using Hirshfeld and quantum theory of atoms-in-molecules techniques. Furthermore, symmetry-adapted perturbation theory analysis of the TPA analogues has revealed that a periodic arrangement of energetically stable dimers with significant electronic coupling is essential to contribute high charge-carrier mobility to the overall crystal.

Significantly improved photovoltaic performance of the triangular-spiral TPA(DPP-PN)3 by appending planar phenanthrene units into the molecular terminals

A novel triangular-spiral conjugation molecule of TPA(DPP-PN)3 using triphenylamine (TPA) as the donor core, diketopyrrolopyrrole (DPP) as the acceptor arm and phenanthrene (PN) as the planar arene terminal, as well as its counterpart of TPA-3DPP without the PN terminal, were prepared. Their UV-vis absorption, electrochemistry and thermal stability, as well as hole mobility were investigated. Significantly red-shifted UV-vis absorption profiles were observed for TPA(DPP-PN)3 instead of TPA-3DPP in solution and solid state. A hole mobility of 1.67 × 10-4 cm2 V-1 s-1 was obtained for the TPA(DPP-PN)3/PC71BM blended film, which is 2.1 times higher than that of the TPA-3DPP/PC71BM blended film. Furthermore, the TPA(DPP-PN)3/PC71BM-based organic solar cells presented better photovoltaic property with a maximum power conversion efficiency of 3.67%, which is 1.9 times higher than that of TPA-3DPP/PC71BM-based devices. The results confirm that appending planar PN terminals to TPA-3DPP with a triangular-spiral shape is an efficient approach to improve the photovoltaic performance of its resulting molecules.

Original Suzuki–Miyaura Coupling Using Nitro Derivatives for the Synthesis of Perylenediimide-Based Multimers

A series of perylenediimide (PDI)-based multimers were synthesized using an original Suzuki–Miyaura Coupling (SMC) reaction. The new approach considers the reaction between 1-nitroPDI as the electrophilic reagent with a wide variety of boronic esters to reach PDI dimers, trimers and tetramers which are of particular interest as Non-Fullerene Acceptors (NFAs) in organic photovoltaics. In this work, we compared the reactivity of 1-bromoPDI and 1-nitroPDI towards this pallado-catalyzed cross-coupling reaction. Considering that 1-nitroPDI is more accessible in terms of selectivity, time reaction, purification efficiency, atom economy, etc, we have shown that the use of nitroarenes is largely favored in the preparation of these PDI-based multimers. The latter were characterized with determination of their spectroscopic and electrochemical properties. With the aim of extending this SMC reaction to N-annulated PDI analogues, an original and efficient transformation of nitro-PDI into pyrrole-fused PDI was found as an alternative to the well-known reductive Cadogan cyclization. The SMC reaction was applied to bromo and nitro N-annulated PDI derivatives, and DFT calculations were accomplished in order to clarify the oxidative addition step of the cross-coupling and understand the difference of reactivity between the bromo- and nitro-PDI based electrophiles.
