Molecular beam deposition of crystalline layers of polar perhydrotriphenylene inclusion compounds characterised by second harmonic generation microscopy

Polar inclusion compounds of perhydrotriphenylene (PHTP) were grown in nm t o mu m thick crystalline layers on glass and sapphire substrates. Nucleatio n was facilitated by using silanised glass. Second harmonic generation micr oscopy and confocal second harmonic generation microscopy were used to iden tify the deposition of polar PHTP-guest layers and to determine the growth direction. Channels formed by the inclusion compound were found to grow par allel to the glass substrate.
