Abstract

The work reported here is the result of an experimental calo-rimetric investigation of a series of intermolecular complexes which fall into the category labeled “charge transfer” complexes (1–5) or “donor-acceptor” complexes (4). Specifically, the systems studied consist of two compounds which are postulated to have an electron donor-acceptor relationship to one another (1). The donor molecules used were benzene, the methyl substituted benzenes, thianthrene, naphthalene, acenaphthalene, phenanthrene, and pyrene. The acceptor molecules were tetracyanoethylene (TCNE), 1,3,5-trinitrobenzene (TNB), and picric acid (1,3,5-trinitrophenol or PA). The calorimetric experiments were carried out in methylene chloride solution, all possible donor-acceptor combinations were used, and a 1:1 acceptor to donor complex constitution was assumed. These calorimetric investigations are the first studies of this type.
