Аннотация:The centimeter-sized naphthalene, anthracene, and tetracene crystals have been grown from thevapor phase. An isothermal thermogravimetric method for determining the sublimation enthalpy during crystal growth under conditions of classical physical vapor transport is proposed. The sublimation enthalpy has been calculated using the obtained approximate equation for the temperature dependence of the intensity of the flux of molecules sublimating from the solid surface in the quasi-steady-state mode. The sublimation enthalpies of the linear acenes under study have been determined in narrow temperature ranges to be 71 ± 2 kJ mol–1 (328–353 K), 96 ± 3 kJ mol–1 (423–458 K), and 124 ± 11 kJ mol–1 (513–573 K) for naphthalene, anthracene, and tetracene, respectively. The found values are in good agreement with the experimental data in the literature.
