The realization of self-assembled mol.-electronic films, whose room-temperature transport properties are controlled by quantum interference (QI), is an essential step in the scale-up of QI effects from single mols. to parallel arrays of mols. Recently, the effect of destructive QI (DQI) on the elec. conductance of self-assembled monolayers (SAMs) has been investigated. Here, through a combined exptl. and theor. investigation, we demonstrate chem. control of different forms of constructive QI (CQI) in cross-plane transport through SAMs and assess its influence on cross-plane thermoelectricity in SAMs. It is known that the elec. conductance of single mols. can be controlled in a deterministic manner, by chem. varying their connectivity to external electrodes. Here, by employing synthetic methodologies to vary the connectivity of terminal anchor groups around aromatic anthracene cores, and by forming SAMs of the resulting mols., we clearly demonstrate that this signature of CQI can be translated into SAM-on-gold mol. films. We show that the conductance of vertical mol. junctions formed from anthracene-based mols. with two different connectivities differ by a factor of approx. 16, in agreement with theor. predictions for their conductance ratio based on CQI effects within the core. We also demonstrate that for mols. with thioether anchor groups, the Seebeck coefficient of such films is connectivity dependent and with an appropriate choice of connectivity can be boosted by ~50%. This demonstration of QI and its influence on thermoelectricity in SAMs represents a critical step toward functional ultra-thin-film devices for future thermoelec. and mol.-scale electronics applications.
