Samples of single-crystal plates of p-terphenyl (3Р) and its derivative with terminal substituents–Si(CH{sub 3}){sub 3} (TMS-3P-TMS), up to 25–30 mm in size and 400 μm thick, have been obtained for the first time by the solvent–antisolvent growth method. The crystal structure at temperatures of 293 and 85 K is refined for 3Р and solved (for the first time) for TMS-3P-TMS using X-ray diffraction. The habit of crystals and their surface morphology are investigated by methods of optical and laser confocal microscopy. The influence of substituent terminal groups -Si(CH{sub 3}){sub 3} on the growth and structure of TMS-3P-TMS crystals is analyzed based on experimental data. The optical absorption and photoluminescence spectra of solutions and crystalline samples are investigated.
