“…On this substrate (pristine and damaged by ion impact), the growth of CuPc and FePc was studied with AFM, HREELS and other techniques [302,303]. In addition, for CuPc the growth behaviour was compared for graphene/Ni(1 1 1) (resulting in a smooth graphene layer) and graphene/Cu-foil (resulting in a rough graphene layer) [304].…”

“…The van der Waals (vdW) interactions are dispersion forces between charge-neutral molecules. The interactions of many organic molecules belong to this category, such as fullerene C 60 , − metal-phthalocyanine (MPc), − pentacene ,− perfluoropentacene, , rubrene, perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA), − 7,7,8,8,-tetracyanoquinodimethane (TCNQ) and its fluorinated derivative 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F 4 -TCNQ) − and even crystalline polymers . The molecule structures of C 60 , MPc, pentacene, perfluoropentacene, PTCDA, TCNQ, and F 4 -TCNQ are shown in Figure , since they will be frequently discussed in this review.…”

“…Such phenomenon is often termed as the π–π interaction. , The π–π interactions between graphene and aromatic π-conjugated molecules play a significant role in the orientation of planar organic molecules on graphene, which is also widely known as the graphene template effect . MPc molecules (e.g., M = Cu, Fe, Co, and AlCl) and substituted MPc (e.g., F 16 CuPc) are well-known to form a “face-on” orientation on the graphene interface, relative to the “edge-on” orientations that are usually found on the deposition of these molecules on amorphous substrates such as SiO 2 or glass. ,,,,,,, Similarly, the graphene-templated orientation of organic molecules has also been discovered for pentacene ,, C 60 , , p -sexiphenyl (6P), and dibenzotetrathienocoronene (DBTTC) molecules, revealing a general mechanism behind their assembly behavior.…”

Molecular epitaxythe process of growing a crystalline overlayer onto a substrateat the two-dimensional (2D) material interfaces, opens new avenues toward the integration of 2D materials with a large variety of functional molecules. The emerging field of controlling molecular epitaxy on 2D materials interfaces toward functional heterostructures and novel optoelectronic devices clearly requires the understanding of the interplay between molecular interactions at the interfaces. In this article, we review the mechanisms governing molecular epitaxy on 2D materials, with an emphasis on the diverse interactions involved, including (i) the intermolecular interactions between the deposited molecules, (ii) the molecule–2D material interactions, and (iii) the molecule–substrate interactions through the 2D material. The interplay between these interactions determines the dimension, interfacial orientation, crystal packing, morphology, and electronic properties of the epitaxial layer. We further review the state-of-art applications, which might benefit from tailoring molecular interactions at 2D materials interfaces.

“…This peak corresponds to an interplanar spacing of 3.20 Å which is characteristic of MPc's lying face-on on the substrate. 24,38,39 The peak at 2Θ = 26.36°i s the characteristic (002) peak arising from multilayer graphene. 38 The relatively weak peak at around 2Θ = 7.06°p resent in the XRD patterns is either due to the fact that graphene is not fully coalesced or because a small amount of graphene has been detached/washed away during the transfer process, thus leaving the bare surface exposed to the ZnPc flux and producing ZnPc with an edge-on geometry.…”

Influence of the Underlying Substrate on the Physical Vapor Deposition of Zn-Phthalocyanine on Graphene

Graphene shows great promise not only as a highly conductive flexible and transparent electrode for fabricating novel device architectures but also as an ideal synthesis platform for studying fundamental growth mechanisms of various materials. In particular, directly depositing metal phthalocyanines (MPc’s) on graphene is viewed as a compelling approach to improve the performance of organic photovoltaics and light-emitting diodes. In this work, we systematically investigate the ZnPc physical vapor deposition (PVD) on graphene either as-grown on Cu or as-transferred on various substrates including Si(100), C-plane sapphire, SiO2/Si, and h-BN. To better understand the effect of the substrate on the ZnPc structure and morphology, we also compare the ZnPc growth on highly crystalline single- and multilayer graphene. The experiments show that, for identical deposition conditions, ZnPc exhibits various morphologies such as high-aspect-ratio nanowires or a continuous film when changing the substrate supporting graphene. ZnPc morphology is also found to transition from a thin film to a nanowire structure when increasing the number of graphene layers. Our observations suggest that substrate-induced changes in graphene affect the adsorption, surface diffusion, and arrangement of ZnPc molecules. This study provides clear guidelines to control MPc crystallinity, morphology, and molecular orientations which drastically influence the (opto)electronic properties.
