Covalently Patterned Graphene Surfaces by a Force-Accelerated Diels–Alder Reaction

Abstract

Cyclopentadienes (CPs) with Raman and electrochemically active tags were patterned covalently onto graphene surfaces using force-accelerated Diels-Alder (DA) reactions that were induced by an array of elastomeric tips mounted onto the piezoelectric actuators of an atomic force microscope. These force-accelerated cycloadditions are a feasible route to locally alter the chemical composition of graphene defects and edge sites under ambient atmosphere and temperature over large areas (∼1 cm(2)).

Modulation of the exfoliated graphene work function through cycloaddition of nitrile imines

“…50 It was found that graphene models are more stable as open-shell singlet states than as closed-shell singlet and open-shell triplet states. 51 For this purpose, all calculations reported here were performed using Gaussian 09 (see details in the ESI ‡) using the (U) M06-2X level of theory 52,53 and 6-31G(d) basis set [54][55][56][57][58] as this method is reported to provide excellent energy values for cycloaddition reactions. 59 This approach therefore takes into account the dispersion interactions because the sp 2 framework of graphene can interact through p-stacking and CH-p interactions with the dipolarophile.…”
