Photoemission from Molecular Crystals
Physica Status Solidi (a), 1972A simple model describing the photoelectron emission from molecular solids has been proposed. A new extrapolation procedure resulting from the model and allowing to determine solid-state ionization energies has been derived. Photoemission curves as calculated from the model are in a reasonable agreement with experimental data.

Melting of superheated molecular crystals
The Journal of Chemical Physics, 2017Melting dynamics of micrometer scale, polycrystalline samples of isobutane, dimethyl ether, methyl benzene, and 2-propanol were investigated by fast scanning calorimetry. When films are superheated with rates in excess of 105 K s−1, the melting process follows zero-order, Arrhenius-like kinetics until approximately half of the sample has transformed ...

Molecular Recognition at Crystal Interfaces
Science, 1991Nucleation, growth, and dissolution of crystals have been studied by stereochemical approach involving molecular recognition at interfaces. A methodology is described for using ''tailor-made'' additives designed to interact stereospecifically with crystal surfaces during growth and dissolution.

Molecular crystals: the crystal field effect on molecular electronic structure
Journal of Molecular Modeling, 2003The effect of crystal packing on the electronic structure of organic molecules was modeled by incorporation of the external electrostatic potential into the semiempirical Hamiltonian of the molecule. An empirical correction procedure was devised in order to compensate for systematic errors in the charge distribution typical of semiempirical methods ...

Photofunctional molecular crystals
2022Novel solid state photofunctional materials have been designed, and their structure-properties relationships are investigated. This thesis focuses on two distinct photofunctional properties: generating photomechanical motion in photoswitch-based crystals and ‘afterglow’ emission from organic alloy crystals and novel organic emitters.

Photoinduced peeling of molecular crystals
Chemical Communications, 2019Photoisomerization of cis-dimethyl-2(3-(anthracen-9-yl)allylidene)malonate in a block-shaped microcrystal initiates a phase separation and delamination of the reacted layer from parent crystal.
